how to fix a self assigned ip address on mac

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.

how to fix a self assigned ip address on mac

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.

Self-assigned IP address

I sometimes have problems dropping IP addresses after changing networks and get stuck with a self-assigned IP that I cannot drop by hitting the renew "DHCP Lease" button on my Mac OS X.5 Leopard. The only work around is to manually give myself a "good" IP, shut down my computer, then boot up and switch back to regular DHCP. Any ideas?

It must be the problem with your IP Address. 169.254.*.* is an address reserved for local ip address. If your DHCP server uses that address then you could not connect to the internet.

Please check this Internet connection does not work with an IP address space of 169.254.xxx.xxx from ISP, router, or manual configuration

Connecting using the plain WEP password was allowing me to connect (to a link sys Wi-Fi) but DHCP didn’t work and I got the dreaded self-assigned address.

To fix it we logged in using the HEX version of the same key (which we found by looking on the router via a wired connection).

On network preferences, select Network Name Join Other Network... then type in the name of your own network, select WEP...HEX. and enter the HEX version of the WEP key.

how to fix a self assigned ip address on mac

IP address over ethernet is self-assigned when using a gigabit adapter

I'm using a MacBook Air, M2, running Sonoma 14.1.2.

It connects OK to the internet over Wi-Fi but cannot connect over ethernet when using a gigabit adapter in an outbuilding in the garden.

This is the situation:

The garden is small, and we have an office there, but the wi-fi is unreliable as the office has thick walls; therefore, I need to be able to use the ethernet connection we have from the living room in the house to the office .

  • Macbook can connect on wi-fi everywhere in the house and office (but unreliably in the office).
  • Macbook can connect on ethernet in the living room , straight from the router, using a Belkin USB-C LAN adapter.
  • Macbook cannot connect on ethernet in the office , using same Belkin USB-C LAN adapter. It gets a self-assigned IP address, or a green light, but no data comes through.
  • Husband's iMac can connect on ethernet in the office. His iMac doesn't need an adapter, it has an ethernet port.
  • Husband's iMac cannot connect on ethernet in the office if ethernet cable is coming out of a TP-Link TL-SG1005D, 5 Port Gigabit Ethernet Network Switch.

Troubleshooting (none of this solved the problem, apart from number 4 temporarily)

  • Re-started router, laptop.
  • Contacted my internet provider to check there were no issues with our line.
  • Started Macbook on safe mode.
  • Created new user in Macbook with admin rights and connected succesfully in the office. This happened only once and hasn't happened again.
  • Re-installed previous operating system MacOS Ventura after using repair utility.
  • Upgraded to Sonoma.
  • Renewed DHCP lease.
  • Added DNS servers: 8.8.8.8, 8.8.4.4, 1.1.1.1, 9.9.9.9

Summary: MacBook air would only connect to the internet if straight from the router (with the Belkin adapter, as it does not have an ethernet port). If I need to add another step to this physical connection (through the CAT5e socket at the wall in the office, or the TP-Link switch) it self-assigns an address. This is the case for husband's iMac too, it would only work if there are no extra physical steps in the office, i.e. not through the TP-Link switch.

I have tried everything I can think of, and I have read many threads with no solution.

If anyone can crack this horrible puzzle, I would be SO grateful. Thanks!

MacBook Air, macOS 14.1

John, thank you very much for taking the time to read my post and answer it. I really appreciate it, as it has been such a frustrating experience to make any sense of the situation with not much knowledge of any of the parts.

I think you're on the right track, and your suspicion is probably correct, based on your explanation of how Gigabit Ethernet is unforgiving of faults.

I did spot two new things after I wrote this post, which may corroborate your suspicion:

The iMac (which is connecting to the ethernet in the office) is doing the following:

  • The speed at which it connects to the internet is so much slower than when connecting a computer to the ethernet straight from the router in the living room.
  • The speed at which the hardware (from System Settings -> Ethernet -> Details -> Hardware -> Configure -> Automatic -> Speed) is 10baseT , which is super slow but, interestingly, automatically chosen as such by the iMac.

I'll let you know what I find once I isolate where the problem is!

Dec 2, 2023 2:54 PM in response to srome21

The extensive troubleshooting you performed seems to indicate the problem lies somewhere between the CAT5e socket at the wall in the office and the router. I realize the iMac was able to connect using that same office socket, but only without the Belkin adapter. Introducing the Belkin adapter causes it to fail. You know the adapter itself is ok though, because you can successfully use it when you connect directly to the router in the living room.

If my understanding is correct, the explanation may be that the Belkin adapter is unable to negotiate a connection through that office socket and the router. What that suggests is a Cat5e connection that is not actually meeting the rigorous Cat5e standards. The Belkin adapter itself may be ok but the connection isn't good enough.

The fact the TP-Link switch causes the same failure may be another indication of that substandard office connection. You didn't say whether it was involved in it or not though, or if you tried a different cable.

Lacking some independent testing equipment, the most expedient way of confirming my suspicion is to completely bypass that office socket with a sufficiently long Ethernet cable. Gigabit Ethernet is unforgiving of substandard connectors or wiring. Not enough twists per inch, or a broken / intermittent connection, and things won't work.

Try bypassing that office Ethernet port. I think you will find the culprit will be in the office connections or cables you had been using, and your challenge is to isolate the cause.

The following is paraphrased from my notes regarding a discussion I had with an Apple engineer several years ago. The subject of the discussion was the amount of time it took to establish a fast and reliable Ethernet connection. It was taking on the order of 30 seconds or so, and I was wondering why it took so long to establish compared to a comparably fast wireless connection.

"The minimum protocol required to enable an Ethernet connection is 10Base-T.

"When you connect a 1000Base-T (1 GigE) switch, adapter, or other device, the protocol that communicates the Speed / Duplex / Flow Control between the devices is known as Auto-Negotiation. Auto-Negotiation requires only 2 pairs of conductors. The maximum available capability is subsequently shared between the devices.

"If the maximum shared speed for both sides is agreed to be 1 G then the link needs 4 pairs of conductors to sustain that speed. If only 2 conductor pairs are available, both devices will conclude the 4 pair connection is unreliable in way, and will then enter a search mode to find a speed that will work on any available 2 pairs of conductors."

The conclusion we reached was that "search mode" is not as fast as wireless due to that negotiation. If the hardware implemented to test that link is determined to be sufficiently compromised, it will abandon that 4 pair operation and revert to a lower speed which is sustained for the duration of the connection.

From that discussion I learned that the apparently simple Ethernet connection is not so simple after all, and yes it confirms our suspicion that your office-to-router link is not conforming to Gigabit Ethernet requirements. It may not even be conforming to 100Base-T requirements. I suspect you will ultimately find one or more broken or intermittent conductors or connections, and that repairing them will solve the problem. The required number of twists per inch is specified. Exceeding even the maximum length of any particular un-twisted pairs of conductors can affect its negotiated speed.

Since that discussion I learned a lot more about Gigabit Ethernet. The paraphrased notes I created at the time are exceedingly brief.

Dec 3, 2023 11:49 AM in response to John Galt

Thanks again, John. I have decided to get a tradesman to have a look, as I think it is likely to be something I cannot easily fix myself, as I don't have the equipment or the knowledge to test the sockets or the cable from the house to the office. Your responses and all the troubleshooting I've done really point to that. As soon as I find out what is going on, I'll share!

Dec 15, 2023 5:26 AM in response to John Galt

Hi John, I wanted to thank you again and tell you how my problem got solved. I'm writing to you from the office, connected to the ethernet from the computer, which couldn't go online before :)

An electrician came today. He worked out that pair 2 was failing (when he connected his tester). This was a simple fix, as one of the ends of the cable in the office was loose. However, I couldn't still use a switch, and the speeds in the officer were 9mbps. We get 65 Mbps in the house.

I mentioned your thoughts, and he went ahead and tidied up the connection in the office by shortening the bits of cable in the socket. At this point, he realised some of the cables were brittle and cut enough of them off to get rid of them and reconnect them again.

As a result, things got fixed; I'm using a switch and getting the same speed as in the house.

I'm so grateful for your patience in reading all my troubleshooting and recommending the next steps for me. I'm so happy things are fixed now! It took so much time and effort, and when you responded, I was at the end of my tether with this problem, so hearing your thoughts and recommendations was very valuable. Thank you.

Dec 15, 2023 7:41 AM in response to srome21

Great! Glad to hear it.

Thank you for the explanation of the reason. When you find an intermittent connection due to brittle conductors it's very likely all them are in need of attention, so the electrician did it right.

I imagine it didn't cost very much.

Dec 3, 2023 12:01 PM in response to srome21

A reasonably qualified electrician should be able to diagnose the problem in no time. Don't go crazy searching for a network engineer or something.

Need to Fix Self Assigned IP Address Error on Mac?

There can be various reasons why the internet on your Mac isn’t working properly. One example is the Self Assigned IP Address error, which many Mac users have reported . In this error, although your device is connected to a network, the internet stops working. 

In order to recognize this error, simply look below your network connection to find “Self Assigned IP Address”. This issue can arise due to several factors, such as poor internet connection or corrupted Plist files.

The good news is you can easily fix self assigned IP address error on Mac by many practical methods. To help you out, we have gathered some of the most effective solutions below. However, before opting for any troubleshooting fixes, identify the main cause first.

So, let’s begin!

1. Power Cycle Modem/Router.

Before you jump to some serious fixes, determine if the problem is related to your internet connection. Check to see if the Wi-Fi works fine on other devices connected to the same network. If all of them are experiencing poor connectivity or similar issues, we recommend you power cycle the modem.

To do so, follow the steps below:

  • Start by unplugging the modem from the power supply. 
  • Wait for a while. 
  • Then, reconnect the modem to the power source and press the power button.

This should fix the self assigned IP address error on Mac. 

2. Renew the DHCP Lease.

A DHCP lease is an IP address assigned to a device on a network for only a limited period of time. Every time you connect to a wireless network, the DHCP server assigns a new IP address. 

So, when you encounter the self assigned IP address error on Mac , you can manually renew the DHCP lease. 

Here’s how to do it:

  • Go to the Apple menu from the top-right corner. 
  • Next, click on System Preferences . 

System Preferences on Mac

  • From the new window that appears, select Network . 

Network Settings on iPhone

  • From the left sidebar, click on your connected Wi-Fi or Ethernet network and select Advanced . 

Wi-Fi settings on iPhone

  • Now, go to the TCP/IP tab and select Renew DHCP Lease . 

Renew DHCP Lease

  • Finally, click on OK to save these changes. 

Once done, the self assigned IP address error on Mac should be solved. If not, follow the next solution from this guide.  

3. Create New Network Location.

If directly renewing the DHCP lease was of no use and you’re still encountering the Self assigned IP address error on Mac, then this method is for you. Just create another network location and then reset your Mac’s IP address. 

Each network location includes settings for a specific network port. That way, you can easily switch between various network locations without having to reconfigure every time.

Below are the steps you must follow:

  • From System Preferences , select Network . 
  • After that, click on the drop-down menu icon next to Location . 
  • Click on Edit Locations . 

Self Assigned IP Address Error on Mac

  • Then, click on the + icon and enter the name of your network in the text field. 
  • Click on Done and choose your Wi-Fi network from the left pane. 
  • Now, choose Advanced . 
  • Click on the TCP/IP tab and select Renew DHCP Lease . 
  • At last, select OK to confirm these changes. 

4. Delete the PLIST Files.

The Plist files or Preference files contain important data related to configuring apps and services within your macOS environment. Occasionally, these files can become corrupt, damaged, or even get attacked by malware or a virus.

To handle such situations, you can discard the Plist files to eliminate the error. This method will not harm any program or your computer so it is safe to follow.

Use the instructions below to do it:

  • Launch Finder from the taskbar. 
  • After that, click on Go from the top bar and select Go to Folder . 

Self Assigned IP Address Error on Mac

  • Now, copy and paste the following in the text field and click on Go :
  • From System Configuration , right-click on these folders and select Move to Trash :
  • Finally, reboot your device and check if you’re able to connect to the internet now. 

5. Set Service Order.

At times, you may be connected to more than one type of network interface. If you’re getting the self assigned IP address error on Mac when connected to one of them, you can change the service order to prioritize another network type.

Here’s how:

  • Head over to the Apple logo and click on System Preferences . 
  • From there, click on Network . 
  • Next, click on the gear icon from the bottom-left corner and choose Set Service Order . 

Set Service Order

  • From the new window that shows up, drag your network to the top. 
  • Lastly, click on OK .

6. Switch to Google DNS.

Your ISP server could be unreliable when it comes to keeping their servers up and running. It’s also possible that they have restricted access to certain web pages. In this case, you may experience slow service and even encounter self assigned IP address error on Mac.

Switching to a Google DNS might be a good option, not only to load pages faster but to access geo-restricted content. 

Follow the steps below to do it:

  • From the System Preferences window, go to Network . 
  • After that, click on the lock icon . 
  • Provide your login credentials. 
  • Now, click on your network from the left pane and select Advanced . 
  • Click on the DNS tab from the top and select ‘ + ’ from the bottom-left corner. 

Self Assigned IP Address Error on Mac

  • Type in 8.8.8.8 and 8.8.4.4 in the DNS servers field and select OK . 
  • Lastly, reboot your Mac. 

7. Reset the Firewall on Your Mac.

If you’ve not properly looked into the Firewall settings, it’s high time you do so. This protection program can sometimes show extreme behavior and block sites for safety. When that happens, you may receive the self assigned IP address error on Mac.

To resolve this, simply reset the Firewall to bring back the default configuration of the program. Hopefully, this will allow you to access content that wasn’t visible earlier.

Here’s what you need to do:

  • Go to Finder and select Go from the top. 
  • Click on Go to Folder . 
  • Next, type in the following in the text field and click on OK :
  • Now, delete the com.apple.alf.plist file. 

Self Assigned IP Address Error on Mac

  • Restart your computer, and hopefully, this method will resolve your issue.

That was it! You’ve now made it to the end of our guide on how to fix self assigned IP address error on Mac. for more tips or suggestions, head over to the comment section below and help fellow readers.

How to Find and Change the IP Address on Your Mac

Quick links, how to find your ip address on a mac, how to change the ip address of your mac, how to set a manual ip address on macos, ip address conflict troubleshooting, public vs. private ip addresses on mac.

  • You can find and change your Mac's IP address through the Network panel in System Settings or by using Terminal commands.
  • Changing your IP address can help resolve network conflicts, such as when you receive an "another device is using your IP address" message.
  • If you set a manual IP, it's important to reserve this in your router to make sure your Mac consistently uses the same address.

Need to double-check your Mac's IP address or adjust it to avoid a network conflict? We'll show you how to easily find and change the IP address of your Mac.

The easiest way to check your Mac's IP address is through the Network panel in System Settings . Click the Apple menu in the top-left of your screen and choose System Settings to open it, or use Cmd + Space to search for "settings" with Spotlight.

Here, click Network from the left sidebar to open the relevant menu. Your current network shows at the top, with a green Connected dot—this is Wi-Fi , assuming you're using a wireless connection. Click the one you're using.

On the resulting page, you'll see the name of your current network at the top. Click the Details button next to this to open a new window with full information about the network.

There, you'll see an IP address field, which displays the current private IP address of your Mac on your network. For convenience, the Router 's IP address is also shown. You can select these addresses to copy and paste them elsewhere.

View Your Mac's IP Address Through the Terminal

The above method is quick and reliable, but you can also see your Mac's IP address using a Terminal command if you don't want to click through multiple menus. Open Terminal by searching for it on Spotlight ( Cmd +Space ).

Next, enter the following command to show your IP address on a Wi-Fi connection:

For an Ethernet connection, use this command instead:

Either way works; if you can memorize this handy Terminal command , it's a bit faster than clicking through the System Settings menus.

While viewing your computer's IP address is enough in some cases, what about when you need to get a new IP address on your Mac? This is necessary if you see the "another device is using your IP address" message, though you can change your IP address for other reasons too.

To change your Mac's IP address, head back to the same Network menu mentioned above. On the window where you confirmed your Mac's IP address, click the TCP/IP menu on the left. This shows more details about your Mac's current network connection. Next to Configure IPv4 , you'll probably see Using DHCP .

DHCP, or Dynamic Host Configuration Protocol , allows routers to automatically manage IP addresses. This is why when you connect a new device to your network, you don't have to manually select an open IP address for it.

To get a new IP address from your router, click the Renew DHCP Lease button. This will result in your computer releasing its IP address and getting a new one, which should resolve any duplicate IP errors.

If you want more control over your Mac's network settings, you can assign an IP address manually (also called a static IP). With this option, the specified address will not change for your device, which can further help resolve issues with duplicate IP addresses.

To set a static IP address on your Mac, return to the TCP/IP tab mentioned above. In the Configure IPv4 field, click Using DHCP and change it to Using DHCP with manual address .

You can also choose Manually if you want. However, the former option is more convenient as it only has you specify the IP address, so you don't need to confirm other information like your router's IP.

Finding an Unused IP Address

When setting a manual IP, you'll need to choose an IP address that isn't already in use on your network. Otherwise, you'll create a duplicate IP problem. While you can log into your router to check IP addresses in use , it's faster to check for an open one using the Terminal.

To do so, you first need to know the IP format of your network. You'll find this on the TCP/IP tab visited earlier—the address of the Router is the format your network uses. This is often 192.168.0.X (with the last digit being unique to each device) but you should double-check what yours is.

Once you know, use Cmd + Space to open Spotlight and search for Terminal. Then enter the following command to ping an address and see if it exists on your network, replacing the address with one you want to use:

If this results in something like 64 bytes from 192.168.0.102 followed by other information, that means a device with that address exists on your network and is responding to your ping. Don't use that address for your Mac; try the ping command again with a new address until you find one that's available.

If you have lots of devices on your network, you might wish to use the arp -a command to filter out unavailable options. This displays all IP addresses on your network at once, showing what's already in use.

When your ping to an IP repeatedly shows Request timeout , you've found a free address. You can enter that IP address in the IPv4 Address field of the Network settings page. Once you do this and confirm with OK , your Mac's IP address will stay the same unless you change it.

Reserving a Manual IP in Your Router

For best results, when you set a manual IP address on your Mac, you should also reserve that address in your router. That way, your router knows that your Mac expects to always use the same address.

To open your router's management panel, open your browser and type the IP address that appears next to Router in the TCP/IP panel you used earlier. You'll then need to log in with your router admin and password, which is different than the password you connect to Wi-Fi with.

If you've never logged into your router before, check Routerpasswords.com to find the default for yours, then be sure to change it for security. And if you're not familiar with working in a router, you may want to read our general router introduction first.

IP address reservation options will differ slightly depending on your router. On my ASUS router, for instance, the relevant menu is under LAN > DHCP Server . Turn Enable Manual Assignment on, then in the box below, you can select a device and reserve an IP address for it. You don't need to change the DNS Server , but you may want to set the Host Name , Description , or similar box to remember what's what.

Given that the router identifies devices by MAC address (not related to the Mac platform), you'll need to pick out your Mac from the list. I've previously named my devices (under Network Map ) to make them easier to identify. If you're not sure which item is your Mac, you'll need to find your Mac's MAC address manually.

See our guide to static IP addresses for more help.

If you needed to change your Mac's IP address because you saw an "another device is using your IP address" error, resetting and renewing your IP address or assigning a manual IP should have fixed the problem. If not, we have a guide to fixing IP address conflicts that you should consult next.

No two devices on your network can have the same address, since your router won't know which is which. This is why you see this message, which shouldn't happen unless your router is acting up or you've manually assigned a duplicate address.

However, it can also happen if a computer is in hibernate mode for a long time; when it wakes up, it might have an old IP address that your router has since assigned to something else. In that case, releasing and renewing the address as described above should fix it.

Finally, we should quickly mention the two different kinds of IP addresses for clarity.

Everything we discussed above pertains to private IP addresses, which are used only on your network. Most home networks use the same range of addresses (often starting with 192.168.0.X ), but those values are only used by your local network. A manual (or static) private IP makes it easier to locate devices on your network by their IP addresses.

In contrast, your public IP is what the rest of the internet sees when any device on your network goes online. While you can pay your ISP for a static IP address, a dynamic public IP is fine for most people. Your public IP doesn't affect the "another device is using your IP address" error that you might see on your Mac.

To find your public IP, simply Google "what is my IP address" or visit a site like MyIP.com . We've compared public and private IPs if you'd like more info. And if you want to change your public IP, try one of the best VPN services .

We've looked at how to view your Mac's IP address, as well as changing it if needed. In most cases, you can rely on DHCP and don't need to manage IP addresses manually. While setting addresses by hand does have its uses, the increased overhead isn't worth it unless you're doing so to troubleshoot a problem.
