Wi-Fi has Self-Assigned IP Address

my macbook pro cannot connect to the internet via Wi-Fi. It always say "Wi-Fi has self-assigned IP address 169.xxx.xxx.xxx and not be able to connect to Internet." or sometimes "Wi-Fi has no IP address". What can I do?

MacBook Pro, Mac OS X (10.7.1)

I had the same problem IT told me to switch my wifi incryption from WEP to WPA. Called my internet provider and had them switch it, in two seconds. Now my MBP connects just fine.

I have the same problem. Why can my macbook and ipod get on the same network using WEP?

Jan 10, 2012 10:25 AM in response to samyuwel

Well found the answer. Under network settings in System Pref., click the "assist me" button on the bottom of the screen. It takes you through similar steps as in "Netowrk diagnostics" but this actually WORKS! I can only assume it configures it to WPA instead of WEP.

I have the same issue. it is not the fact that you use WEP or whatever. it is something with the computer or OS. this happens to me almost everyplace i go: home, work, airport, starbucks. It always says no IP address or that i self assigned it and it can't connect.

The only fix i've found is to restart the computer. sometimes this works, sometimes it doesn't.

If you ask the question on these boards people will tell you over and over to check your router or password or change to WEP. None of those are the issue.

I've had this issue more often lately too, maybe only on WEP, which is what most locations use. My pet solution has been to create a new Network Location, then guess the wifi network range and configure everything Manually under the Advanced options of Network Preferences. Usually the network router is at 192.168.1.1, so I set my MacBook's IP Address to something high like 192.168.1.222. Occasionally this still doesn't work because no DNS can be found. Adding a DNS entry with 192.168.1.1 (same address as the wifi router) has done the trick in most cases. If the router won't do DNS by itself, there's always Open DNS, whose IP Addresses are 208.67.222.222 and 208.67.220.220.

The most common addresses for wifi routers are 192.168.1.1, 192.168.2.1, 10.0.1.1, and 10.0.2.1.

None of the options above have enabled my MBP to connect to the internet.

Anyone with additional ideas to try?

Apple support have been completely silent on the matter.

I've been told that when the "self-assigned IP address" message is presented, the 169. at the beginning is an indication of the problem, thought I would throw that in there incase someone could elaborate or discredit this theory...

169.x.x.x address is a self-issued address by the TCP/IP stack on a client when it cannot contact a DHCP server to get one. Generally, it was designed this way so that it would help facilitate easier networking for people who don't know how to properly set up an IP network. Technicallly speaking, you could connect two Macs together with a crossover ethernet cable and wait until they both finally self-assign themselves 169.x.x.x addresses. Once this happens, IP network connectivity will allow for both Macs to talk to each other accross that single ethernet link.

When dealing with a WIFI network, an address of 169.x.x.x usually indicates one of a few things.

1) You somehow manually misconfigured the security type and password for the WIFI network you're tying to connect to.

2) The WIFI network you're on does not have a DHCP server to issue an address.

3) The WIFI network you're on has MAC (no, not the computer Mac, lol) address blocking turned on and doesn't recognize your network card's MAC as a valid client to allow connections.

The gotcha here is that 1 and 3 usually only happens on systems that aren't smart enough check and see if the WIFI connection has accepted the password and OK'd it. On some systems and with some older encryption like WEP, as long as the passcode matched the length of the password required, it would let you connect (or rather it would show you connected but with limited connectivity). This is the state that tends to trick people into thinking they have a good WIFI connection to the network, but something else is wrong, when in fact, they DO NOT have a working connection to the network even at the base security layer (before the TCP stack even begins binding). In situations like this, you must delete the WIFI network and (on a Mac), also clear out the Keychain entries for that WIFI network because that's where the security key is stored. Once this is done, you reconnect to the network and make sure that you're tying in the (usually case sensitive) password as it's given to you. If that still doesn't work, then test with another device. If that device works, then you're still making a clarical mistake on the password on your previous device or that device has other network issues. If the second device doesn't work either, then you've either been given incorrect info for the WIFI network, the WIFI network is misconfigured to not give out DHCP IPs, the WIFI network is doing MAC blocking, the WIFI network router is locked up and not allowing new client connections (power cycle it to fix this), or you're still somehow making a clarical mistake inputting the info for it. Pretty much all these will require you to probably talk to whomever manages that WIFI network if you still want to connect to it.

This worked for me, similar problem. It's most helpful to know that the "self-assigned IP" error is misleading.

Key piece of info here was suggesting a clerical mistake in entering the password. I didn't type it in, but copied and pasted - that was the cause of my problem. Typing it in carefully solved everything. Thanks!

Apr 14, 2013 1:16 PM in response to galaxyglue

You're welcome. You'd be surprised how many times people have asked me to fix their issue with not being able to connect to a WIFI network in the office or somewhere else and 99.99% of the time it's a clerical mistake when they typed their password in. People always deny that until I type it in from their info they provide and it works fine. They go "What did you do?" Nothing, I typed it in correctly... you weren't. :rolleyes:

How to fix “self-assigned IP address” issue on Mac

Ava

  • The self-assigned IP address error occurs when your Mac assigns itself an IP address instead of getting one from the router.
  • This usually happens due to network configuration issues, DHCP server problems, glitches in the firewall settings, unstable Wi-Fi connection, etc.
  • To fix the “self-assigned IP address” error on your Mac, renew DHCP lease, restart your network devices , rejoin your Wi-Fi , or check your network settings . 

Is your MacBook struggling to access the internet, though your Wi-Fi or Ethernet works fine? This can be due to the self-assigned IP address error on your Mac. Worry not!

Here, I’ll share how to fix the internet not working due to a self-assigned IP address error on your Mac to regain a stable network connection. But before we jump into the troubleshooting steps, let’s understand what a self-assigned IP error is.

What does “self-assigned IP address” mean on Mac? 

The “self-assigned IP address” error on Mac refers to a situation where your device assigns an IP address and sets up an ad-hoc network instead of obtaining one from the network router or DHCP (Dynamic Host Configuration Protocol) server.

This self-assigned IP address is not legitimate or acknowledged on the network. That’s why your Mac cannot connect to the internet or other devices on the network, resulting in limited or no network connectivity.

This issue occurs due to several reasons such as:

  • Network configuration conflicts
  • DHCP server unavailability
  • Problems with Mac’s network
  • Unstable Wi-Fi connection
  • Wrong Firewall settings
  • Outdated macOS

But you can fix the issue with a few simple methods. Let’s learn them!

How to fix “self-assigned IP address” error on Mac

There are 12 ways to fix the problem, from simple checks to more advanced changes. It would help if you tried them in the order provided.

  • Check your connection
  • Reboot your network devices
  • Renew DHCP Lease on macOS
  • Rejoin your Wi-Fi network
  • Check your connection settings
  • Reset your Network Preferences on Mac
  • Create a new network location
  • Reset the Firewall on your Mac
  • Set Service Order from Mac’s network settings
  • Change DNS Servers on macOS
  • Check for conflicting IP address
  • Disable VPN

1. Check your connection

Before diving into Mac-specific settings, ensure that your router is functioning correctly and located near your Mac to obtain a valid IP address. Besides, if you are using an Ethernet connection, plug in the cable snugly.  

I also check to validate that the cable has no fault and is in good condition. Moreover, If you are using an old Wi-Fi router, discard it and get a new one to obtain a smoother connection.

2. Reboot your network devices

Restarting both your modem and router can often resolve temporary network glitches. Power off the devices, unplug the cables, and wait a few seconds. It will help them cool down, as excessive heat can cause malfunctions.

After that, plug all cables, connect them to the power outlet, and turn them back on. In the meantime, restart your Mac once to iron out any bugs in macOS.   

  • Click the Apple logo .

Just click the Apple logo → choose Restart on your Mac

3. Renew DHCP Lease on macOS

This method is effective when the assigned IP address may have expired or encountered conflicts. When you renew the DHCP Lease, your Mac requests a new IP address from the DHCP server. It ensures a valid configuration and resolves connectivity issues.  

  • Open the same TCP/IP tab window from Wi-Fi Details, as shown above. 

click tcp/ip, select renew dhcp lease in wi-fi settings

After renewing the lease, check if you can connect to your network. If that doesn’t help, try creating a New Network Location and renewing the lease.

4. Rejoin your Wi-Fi network

Sometimes, simply forgetting and rejoining your Wi-Fi network can solve the self-assigned IP address error on your Mac.   

Click Apple logo, System Settings

  • Turn off Wi-Fi for a few seconds and toggle it on.

click connect in wi-fi on mac

5. Check your connection settings

Verify that your Mac’s network settings are configured correctly. You must opt for the appropriate network settings to obtain IP addresses and DNS information automatically. 

  • Go to your Wi-Fi Details .  I have shown the steps above.  
  • Select TCP/IP from the left panel. 

click tcp/ip, select using dhcp in configure ipv4, select automatic in configure ipv6 in wi-fi settings

You may also try turning off the IPv6, as some users reported it conflicted with the IP address assigning procedure.

  • Click on the drop-down arrow beside Configure IPv6 . 

select dropdown beside configure ipv6, click link local only in wi-fi settings

6. Reset your Network Preferences on Mac 

Resetting the network preferences can help eliminate IP address misconfiguration, causing the internet to not work. So, you must delete specific network connectivity-related files from your MacBook.

  • Launch  Finder .

Go to Folder to clear cache

  • Enter your Mac password to authenticate the deletion.
  • Restart your Mac. It will automatically recreate the deleted files.
  • Log in and connect to your Wi-Fi network.
  • Go to the  TCP/IP  setting again and check the router files.

7. Create a new network location

Creating a new network location lets your Mac start fresh with network settings and eliminate a self-assigned IP address.  

  • Click the  Apple logo →  System Settings .

Click the three-dots icon

  • Wait for a few seconds until your Mac connects to your Wi-Fi.

Repeat the steps of renewing the DHCP lease on your Mac, and then try connecting to your network.

When you try to perform configuration changes to the system, your Mac’s firewall experiences configuration issues. Let’s fix this problem by resetting the Firewall.

8. Reset the Firewall on your Mac

  • In the menu bar, click  Go  → Go to   Folder .

go to library preferences folder on mac

  • Restart your Mac.

After your system boots, it’ll ask you to allow access to numerous programs and services. Enable access depending upon your choice. Then, try connecting to your network and check if the self-assigned IP address error persists.

If you are unsure about deleting the Firewall files, you may temporarily disable it. Toggling off the Firewall on your Mac can help determine if it’s causing conflicts with network connectivity.

  • Select  Network  from the left panel → Choose Firewall .

Turn off your Mac Firewall

  • Restart your Mac and turn it on again.

9. Set Service Order from Mac’s network settings 

Adjusting the service order can prioritize the network interface, ensuring your Mac connects to your preferred network. 

  • Click the  Apple logo →  System Settings →  Network .

click set service order in network settings

10. Change DNS Servers on macOS

Discarding existing DNS and switching to alternative DNS servers can resolve DNS-related issues that may contribute to the self-assigned IP address error.  

  • Open System Settings → Wi-Fi → Click Details beside your Wi-Fi name.

select dns, click plus sign in wi-fi settings

  • Add   these numbers: 8.8.8.8 8.8.4.4 1.1.1.1 9.9.9.9

add dns addresses, click ok in wi-fi settings

11. Check for conflicting IP address 

Ensure that no other devices on your network use the same IP address as your Mac. Check your router’s DHCP client list and verify that all devices have unique IP addresses assigned.

12. Disable VPN 

If you have a VPN service enabled, disable it temporarily to see if it resolves the self-assigned IP address error. Open your Mac’s VPN settings and turn off the VPN connection. 

Bonus fixes 

You may need to attempt more complex fixes if the troubleshooting techniques outlined above do not fix the self-assigned IP address problem on your Mac:

  • Update your Mac to the latest OS version.
  • Verify your Mac is not infected with any malware or viruses. 
  • Ensure your network devices are operating well and there are no hardware problems. 
  • Restart your router or modem
  • Reset NVRAM or PRAM on Mac to clear up the system settings memory. 

Tips to prevent self-assigned IP address issues on Mac

Self-assigned IP address error is indeed frustrating as it prevents your Mac from accessing the internet. So, you must take some precautions to avoid such a nuisance in the future.

  • Regularly update your Mac
  • Try to restart your Mac, router, or other network devices once in a while
  • If your router or modem is outdated, replace it with a new one to get optimal performance. Also, configure the network with high-quality equipment.
  • Connect your Mac to only one active network. I suggest using an ethernet cable for a stable connection.
  • Don’t connect too many devices to your Wi-Fi at a time, as it may create network overcrowding.

Get back your smooth internet access!

Encountering a self-assigned IP address error on your Mac hampers your work, so you should address it ASAP. You can tackle the issue and restore a stable and reliable network connection using these troubleshooting techniques. 

If the problem isn’t resolved, contact Apple Support and seek assistance.

wifi has self assigned ip address 169 254

Hello I recently instakked BIG SUR on my late 2013 macbook pro and I am having trouble tethering my Iphone XR to it. I can tether using wifi, but when I attempt to tether using bluetooth, my phone shows as connected in bluetooth preferences on my macbook and iphone, with the connection/link symbol shown on my iphone, but the internet will not work. In Network the bluetooth Pan shows an orange dot, STATUS: CONNECTED, but underneath it says ‘internet-not-working-self-assigned-ip-address-issue’. Do you have any ideas on how to fix this, I followed your instructions from the link ( https://ioshacker.com/how-to/fix-internet-not-working-self-assigned-ip-address-issue ) on your website, but each time I restart the computer the files that I put into the trash and delete from the trash re-appear in the system configuration folder. Only 2 of the 3 files you suggested to trash are in the folder, – com.apple.network.identification.plist – is not in the folder. Any advice appreciated.

I’m running Monterrey on my MacBook Pro and was having problem with the self-assigned IP and cannot connect to the Internet. I followed what your article suggested, several times, but was still unable to resolve the problem. Are there other suggestions that you think I should try? Thank you.

I just had the same issue and none of the fixes found online worked. I have McAfee Security software installed and there was a service running called McAfeeSystemExtensions. I deactivated the service within the Network settings and problem resolved.

How to Fix a 169 IP Address Error

Having trouble reaching your DCHP servers? There are ways around that

When you can't connect to the internet , and your computer seems to have an IP address that starts with 169, there's a simple explanation. This type of error happens when a Windows computer requests an IP address and doesn't receive one. To fix this sort of 169 IP address error, your computer must be able to obtain a valid IP address from your network.

Causes of 169 IP Address Error

For a computer to access the internet through a network, it needs a valid IP address. The easiest way to make sure this happens seamlessly is through the Dynamic Host Configuration Protocol (DHCP), which is a setting that allows the router to automatically assign an IP address to each device on the network.

When a Windows computer isn't able to communicate with the DHCP server, something called Automatic Private IP Addressing (APIPA) kicks in. It assigns the computer an IP address that starts with 169.254. These IP addresses are only useful on local networks, not the internet.

Without communication between the computer and the DHCP server, and as long as the computer has a 169 IP address, it can't connect to the internet. That's why the fix for this problem involves making sure your computer and the DHCP server can communicate. When that happens, the problem basically fixes itself.

To fix an error where your computer has an invalid IP address that starts with 169, you need to make it so that the networking device in your computer is able to communicate with your network hardware .

Depending on the reason you experience this error, you may be able to accomplish this by resetting the network hardware, telling the networking device in the computer to request a new IP address, or changing some settings in the router .

Power cycle the network hardware . Turn off and unplug your modem and router, and then plug both devices back in. When the network hardware starts back up, and your computer attempts to reconnect to the network, it may be able to obtain a valid IP address.

Use the Windows networking troubleshooter . This automated process takes care of most networking problems, including ones that prevent a computer from obtaining a valid IP address.

Request a new IP address . This is a little more complicated because you need to open a command prompt and enter a series of commands. In most cases, this allows the computer to obtain a valid IP address.

Check the DHCP settings in the router . There are two ways that a router can assign IP addresses. Either the router dynamically assigns a unique IP address to each device, with no input from you, or you must assign a unique static IP address to each device manually.

DHCP is the setting that allows a router to assign IP addresses dynamically. If this setting is turned off, and you haven't set a static IP address for the computer, you won't be able to access the internet.

Disable the router . In some cases, you can fix this type of problem by disabling the networking device and then re-enabling it, or by uninstalling and reinstalling the driver. These are similar processes that both require you to access the Windows Device Manager .

An IP address , short for Internet Protocol address, is an identifying number for network hardware connected to a network. Having an IP address allows a device to communicate with other devices over an IP-based network like the internet.

DHCP using automatic IP address assignment means the same device may have different addresses over time, and there are some reasons you might not want this. To disable DHCP on a Windows computer, press the  Windows + x  keys and click  Settings > Network & Internet > Select a connection > Properties > Edit  to access DHCP settings.

A static IP address is an IP address that is manually configured for a device instead of one that is assigned by a DHCP server. It's called static since it doesn't change, unlike a a dynamic IP address that does change.

What is Self-Assigned IP and How to Fix it

wifi has self assigned ip address 169 254

The self-assigned IP error may prevent your Mac from connecting to the Internet. You may get an Internet connection error messages such as “Wi-Fi has the self-assigned IP address and will not be able to connect to the Internet.” If you investigate this issue further, you will see that the Network pane in System Preferences will also show a notification message saying “Self-Assigned IP” with a yellow dot instead of the regular “Connected” message under the network service, as you can see in the screenshot below. This problem may occur when Mac is connected to a wired, wireless (Wi-Fi), or hotspot connection.

Self-Assigned IP message in Network Settings

This problem occurs when a self-assigned IP address is issued to network interfaces. When this issue happens, not all computers connected to the same network may be affected. For example, in the same home, one Mac may have this problem while other similarly configured Macs may have no problem at all, even though they all are using the same Wi-Fi connection. This may mean that the root of the problem is how the problem Mac is configured. Several factors may cause this issue, such as:

  • Bad cable connections.
  • Not getting an IP from the router or modem.
  • Failure of the DHCP server.

Follow the steps below to address this problem. Please try the steps in this order. After trying each step, check to see if your problem is fixed. If it is not fixed and if you still see the Self-Assigned IP error, move to the next step.

Self-Assigned error troubleshooting steps

Check your router/modem : If you are connected over Wi-Fi, ensure that your Mac is not too far away from the router/modem.

Restart your router/modem and your Mac : You can do this easily. Simply disconnect the power cable to your router/modem. Wait 30 seconds. Then reconnect. Then restart your Mac. Click the Apple  menu and select Restart .

Renew DHCP Lease : On your Mac, open System Preferences and click on Network . Select the network service you want to connect to (e.g., Wi-Fi or Ethernet) and click on Advanced . This will open a new window. Select the TCP/IP tab and click the Renew DHCP Lease . Then click OK .

Renew DHCP Lease button

Check your connection settings : On your Mac, go to System Preferences > Network . Then select the network that shows this error and click Advanced . Select the TCP/IP tab and then make sure that “Configure IPv4” and “Configure IPv6” are set to Using DHCP and Automatically , respectively.

DHCP settings page

Then click on the DNS tab, and delete any DNS servers that are listed there. Select them one by one and click on the minus button to remove them. Do not forget to click OK and Apply when you are done.

Create a new network location : On your Mac, open System Preferences and Network . Open the Location drop-down menu and select Edit Locations . Click the plus (+) button and add a new location, give it a name and click Done . Now you have two locations: Automatic and your new location. Select this new location and then click Apply .

Network Locations

Now, we will add a new Wi-Fi or Ethernet service, whichever you are using. Click the plus (+) sign under the network services on the left, select the Interface (Wi-Fi, Ethernet, etc.) and name it, then click Create . Then click Apply .

New network create screen

Now select the Self-Assigned IP network and then click the minus (-) button to delete it. Then click Apply . Does this newly created service connect?

Reset the system firewall: We can do that by deleting its preference file . Open a Finder window and then click Go and Go to Folder from the top menu bar. Enter /Library/Preferences/ and click Go .

Preferences

Once the Preferences folder is open, find the com.apple.alf.plist file. Delete this file (or place it on your Desktop; if you are not happy with what happens, you can put it back). Then restart your Mac.

macrumors newbie

  • Apr 11, 2014

I did an extensive search for this question and I saw that some people had it resolved but I tried most of the suggestions and didn't have any luck. Last night i was using my macbook on the internet with no problems, went to bed and when I woke up in the morning I tried to check my email and the exclamation point showed up in the top bar. Someone else has a macbook pro in our house and they can get online with no problem, but for whatever reason I've been booted off and can't get back on. I read some comments that said sometimes another computer can "steal" the IP address of your computer and maybe that's what happened to me? When I go into my network preferences it says Status: On but it has a self-assigned IP address 169.254.18.44 and will not be able to connect to the internet. I've tried rebooting the system, rebooting my computer, deleting the wifi passwords off my keychain access, removing the network names and readding them.... nothing seems to work. So... please help? Thanks!

Do this now! 1. Turn off your wireless in your troubled Mac. 2. Open System Preferences->Network tab and highlight your Airport card. 3. In the right hand pane click on the 'Advanced' button. 4. In the main 'Wi-Fi' mini-tab delete all 'Previous Networks' connections. 5. The save out and then go to the application /Applications/Utilities/ Keychain Access.app and in that application find the entries for your wireless router. 6. Then go back into your System Preferences->Network pane and highlight your Wi-Fi card again and use the pane to turn on your wireless again and use that to rejoin your wireless network. 7. Put in your username/password again and rejoin and save the password again. 8. Enjoy.

Macrumors 6502a.

The 169.x.x.x is what is called an APIPA address. Long story short you are not pulling an ip address from a dhcp server (built into the home router in your case). When you don't do this the computer will give you a 169.x.x.x address. have you tried to connect using a wired connection? You may want to isolate maybe the wireless nic having issues. If wired works, console/gui into your router and check its settings.

Just seen this post. I appreciate it's a few months' old now, and I hope the OP's solved his issue by now! The reason for my post is that I have just recovered from a very similar, if not identical, problem. It was an extension conflict that caused my issue. I've written up my solution here, in case it's of use to anyone: https://discussions.apple.com/thread/5507690?start=30&tstart=0

I have this issue... Again... Had it 8 months ago when I moved house- it wouldn't connect to a BT hotspot, it was like it was stuck on a cycle. After a while it would come up with a landing page and it would magically work. Worked fine on a BT router for eight months- not once an issue. Three days ago, it's back with avengance. First few days it would eventually connect if I kept renewing the dhcp licence and keep restarting the laptop and router. Third day in- no amount of restarting is doing anything. Constantly says 'connection time out' or the dreaded 'self-assigned ip'. It isn't the wrong password, nothing in the key chain, and my phone and tablet will context fine. Ideas?

I know this is about a year old, but let me share with you what worked for me: I had the same issue, I had no issue connecting to the internet, then one day, it would connect, but my macbook had self assigned an IP of 169.xxx.xxx.xxx, and said that it would be unable to connect to the internet. I deleted the entry in my recently connected list and turned off my wireless. I took a random guess at what the IP of the router I was using is (because I work at a summer camp, so it's not my router) and tried the usual 192.168.1.x. I changed my wireless from DHCP, and assigned it a 192.168.1.138 IP, with a 255.255.255.0 subnet, then assigned the router as 192.168.1.1. I tried to reconnect, and it worked!

I tried above solutions and nothing helped me. So, finally I fixed my problem by changing wireless mode of my router. My router supports 11b, 11g and 11n modes. And it was set to mixed 11bgn mode with automatic channel bandwidth. 11n mode is preferred and it supports 40 Mhz bandwidth and chooses this bandwidth by default. But when I looked at connection statistics in my mac I found that adapter works in 11n 20MHz. So, I limited my router and set manually 20MHz instead auto. Now mac can detect IP address and everything works great.

To the OP, my Macbook iOS 10.11, had to use airport utility>advanced>DHCP, changed the beginning of the range's last value to 1 and the ending of the range's value to 40. The router restarted and everything worked.

That's not a good idea. If you do that, the router's DHCP server will not be aware of your fixed IP address and may run into conflicts if it tries to assign that IP address to another users. So while assigning a fixed IP address may solve your problem, it may cause problems for other users.

I don't know why the computer is doing that. You could try resetting the NVRAM by cold booting while holding down the command-option-p-r key combination until you hear the boot chime a third time. If you have to use a fixed IP, try to pick one well away from the IP's that the DCHP server seems to be using, perhaps 192.168.1.250 [doublepost=1483123609][/doublepost]You can try this suggestion from https://www.cnet.com/news/fix-self-assigned-ip-addresses-in-os-x/ To reset the firewall, go to the /Macintosh HD/Library/Preferences/ folder and remove the file called "com.apple.alf.plist," and then restart your computer. After the system boots, you may be prompted to allow incoming connections to numerous programs and services, so accept these for now (you can always go to the Firewall settings and deny or remove entries later on) and then try connecting to the network again. While configuration changes from migrating or restoring a system can lead to this problem, at other times major system crashes or power outages can do the same.​

GEA78 said: This is a post for dummies, like myself, so apologize my non-tech language I had the self-assigned IP problem for a week and tried all possible easy fixes: -Reboot modem and devices (twice, sounds like voodoo to me) -Opened system preferences/network/advanced/TCP/IP clicked renew DHCP license -->this would allow sometime one device to connect, but not all devices at once -Opened system preferences/network/advanced/TCP/IP and under configure IPv6 clicked link-local only (same results as above) -Even ruled out "interferences" setting up a 5.2 Ghz network (sorry if I'm using the wrong words, like I said, I'm quite ignorant about this) Nothing worked. My set up was a modem, three powerline extenders that connected via ethernet to 1) an airport express, 2) an i-mac, 3) an apple TV (if you have no idea what a powerline is read side note below on powerlines) I finally understood what the problem was: I could only connect one device at the time, meaning that if I restarted the modem with only one device connected that device would work. If I had two or more connected the remaining devices had a self-assigned IPs. Now for you dummies-like-me out there (I apologize to all techies out there for using wrong words, concepts etc... the modem receives internet from provider and gives it to your home. Internet works in numbers (IP addresses) that tell your modem what devices are connected to it. Now, modems tpically, can connect to one thing at the time. To connect multiple devices you need a router. The router looks exactly like a modem to me (ha ha) it's another little black box, but it will have multiple ethernet ports on its back. Airport express can work as routers (theoretically, as it turned out mine wasn't). The router generates a range of IP addresses, for example, if you are using your airport express as a router you can see the range under system preferences/network/advanced/TCP/IP it could be 10.10.00.01 to 10.10.00.200 (probably not, maybe this is an impossible range, like I said, dummy here, but it will look something like this to other dummies out there). Now, if that is your range and your devices have an IP address of 169.225.xxx.xxx you have a problem. Your device has an IP address not in the range determined by your router= you have no internet. To find the IP address of your device: on a mac system preferences/network/advanced/TCP/IP (I think it's the IPv4 address... maybe and it should have the first bunch of numbers identical to your router or within the range determined by your airport express) on my apple TV it was under settings/general/connection The problem: I finally determined that the problem was that my airport express, for some reason, could only assign one IP address at the time. If all 3 devices were connected, only one would get a valid IP address. Basically, it was not doing its router job. Apple support were sweet as pie but useless and told me it was a problem due to my provider (which wasn't). The fix: I plugged my modem into an old router I had lying around in the house from my pre-airport express days, restarted the modem and everything went back to normal I almost cried for joy. My current set up: 1-cable from provider into modem 2-ethernet cable from modem into router (into the internet port, not one of the numbered ethernet ports) 3-ethernet cable from one of the numbered ports of the router into ethernet port of powerline extender, plugged into a wall 4a-2nd powerline extender plugged into a wall on a different floor. Ethernet cable out of that into my airport express to generate wi-fi 4b-3rd powerline into a different wall plug. Ethernet from that to i-mac 4c-4th powerline into different plug connected through ethernet to my apple TV I hope this helps! Side note on powerline extenders: I live in a big old house with thick walls and wi-fi won't reach everywhere. Powerline extenders are magic portals that allow your internet to travel through walls (ha ha). I have TP-LINK (TP-link TL-PA511 KIT AV500 Powerline Gigabit Adapter Starter Kit, up to 500Mbps). They're $60 a pair on amazon. The way they work: plug an ethernet cable from your router into the powerline, plugged into the wall (they have to be plugged into the wall to work!). Plug another powerline anywhere into your house (within a ridiculous distance, maybe 300 meters/yards or so) and internet will come out of that precious little thing at the same speed it came out of your modem=magic. Side note on airport express: I think my airport express is glitchy but that said, I used airport utility to set it up. How? On a mac just look for airport utility (apple key+ space to open the search tab). From there click on wi-fi. If the utility does not see your airport express reset it with a pen, clicking that little spot that can only be pushed with a pen till the yellow light pulses fast a few times. For me, sometimes, it takes a couple of clickings to get there. Then wait. On the utility after a while if you click on "other wi-fi devices" on the up-left corner you'll see a number in the scrolldown menu: that's your reset airport express. Select it. Set it to create a wi-fi network (if that's what you need) name the network, assign a password and you should be all set. Click to expand...

Determining the self-assigned IP address of a directly-connected counterpart

I have connected two computers, A and B, NIC-to-NIC using an ethernet cable. They have self-assigned their IP addresses—at least, I can see that A has done so, so I infer that B must have also done so. Computer A is a laptop running Windows 10, but I have no keyboard and mouse available for B. From A, how can I determine B's IP address?

On A, this is what I see:

What I've tried (based on https://serverfault.com/a/30742 ):

...which just says "Host is up" and doesn't report anybody else being on the network. I don't claim to understand what nmap is doing (for example, I have no idea what's special about the number 24) but I do know that the same command with 192.168.1.0/24 successfully finds devices on the wireless network to which A is also attached.

jez's user avatar

for example, I have no idea what's special about the number 24

It's a short way of writing the "255.255.255.0" netmask. (Also called "CIDR syntax" from its origins, or "prefix length" because it indicates that the network is specified by the first 24 bits. If you convert 255.255.255.0 from decimal to binary, you'll see it begins with exactly 24 'one' bits.)

However, your actual netmask is not 255.255.255.0 – it's 255.255.0.0, as shown in the ifconfig output. That's a /16. The whole "self-assigned" range is in fact 169.254.0.0/16.

Hosts will send out a few ARP probes as part of the self-assignment process (to ensure that the address isn't already in use). If you connect the computers while Wireshark or tcpdump is already running a capture on the Ethernet interface, you should see both of them revealing their addresses this way.

u1686_grawity's user avatar

  • Relative to everything else I had so far stumbled across, this is a stunningly intelligible explanation of the /24 - thanks. So I conclude that nmap -sn 169.254.0.0/16 would be the way to go. I actually managed the equivalent of that in the end by adapting one of the nmap --help examples to nmap -sn 169.254.0-255.0-255 and found the IP by letting it run for 45 minutes. In future I'll bear in mind the tcpdump tip. I presume there's no way of unilaterally configuring A to say "hey, let's self assign, but with a 24-bit prefix"? That would make it a lot quicker to find... –  jez Apr 1, 2021 at 15:39
  • No, this autoconf mechanism (APIPA) is defined to always use this specific /16 prefix. However, the idea was that it would be accompanied by other Zeroconf services such as mDNS for dynamic discovery. (For example, Windows has mDNS and a few similar alternatives, so as long as both computers run Windows and have the network mode set to “private” you should be able to reach the other computer by its name without needing the exact address. Same goes for macOS and (to some extent) Linux.) –  u1686_grawity Apr 1, 2021 at 16:18
  • But to answer the question, if you specifically wanted to change the prefix, you would have to run DHCP in order to do that instead of relying on autoconf. (And once you have DHCP you no longer need nmap nor tcpdump, as you can just look in the DHCP server’s “lease” table to find the address...) –  u1686_grawity Apr 1, 2021 at 16:22
