wifi has the self assigned ip address and will not connect to internet

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.

Key Takeaways

  • 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.

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.

What is Self-Assigned IP and How to Fix it

wifi has the self assigned ip address and will not connect to internet

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 .

How To Fix Common Connection Wi-Fi Issue: Self-assigned IP On MacBook

Most of the time, WiFi works very well. It’s fast, and it’s convenient. But sometimes, you might experience some issues with connecting to your WiFi network, like your WiFi connection dropping out for no apparent reason. In this article, we’re going to talk about how to fix a common WiFi issue — one that’s related to how your Mac assigns itself an IP address.

Most wireless internet connections require a unique IP address to allow users to access their network remotely. These are typically assigned by a router or other networking equipment via DHCP, a protocol that hands out IP addresses. Some users have reported errors with their network connections when this process is interrupted. These issues are usually easy to fix, but they can cause frustration if you don’t know how.

Apple laptops are known for their reliability, but that doesn’t mean they never have any problems. From common issues like wi-fi dropping out, to more serious problems such as hard drive failure, Apple is renowned for producing solid hardware that is generally quite reliable, and doesn’t break down as much as PCs.

In this article, you will find some solutions that will help you solve the Wi-Fi problem on your MacBook. We use a MacBook as one of our mobile devices to increase productivity. Sometimes in a new place we need to connect our MacBook to the local Wi-Fi network to access the Internet.

Frequently Asked Questions

How do i fix self-assigned ip address on mac wifi.

So, you’ve changed your Wi-Fi network name or password, but can’t seem to connect your MacBook to the network. You’ve tried everything, but you get the dreaded message: “This computer has a self-assigned IP address.” The good news is that this is a fixable problem. If it’s not too late, you can get your MacBook online and start browsing the Web again. When you self-assign an IP address on your Mac, it means that there is a conflict with the existing IP address on your network. This is not an issue, but it can be if you want to connect to the internet. Here are some steps you can take to fix this issue.

Why does my Mac say self-assigned IP address?

The Wi-Fi icon on your Mac displays the IP address of the computer. The IP address can be assigned by a router or DHCP server. Your Mac’s IP address is self-assigned if your Mac has not communicated with a DHCP server or used the built-in DHCP server on your router. Mac users that have enabled the “Airport” feature on their Mac have a built-in DHCP server. While the self-assigning IP address is not an error, it can be problematic if you are not using a DHCP server. If your router or network does not have a DHCP server configured, the self-assigned address can prevent you from connecting to the Internet. The self-assigned IP address might appear when you are connecting your Mac to a network. The IP address comes from a private range of IP addresses, called an RFC1918 range. These addresses are not approved for Internet use, but are often used on local area networks. Self-assigned addresses indicate the computer is set up incorrectly and needs to be reconfigured so that it will use a publicly-reserved IP address.

What is self-assigned IP address for MacBook Pro?

This is a common problem with Macbook pro users. When you connect your Macbook Pro to a Wi-fi network, the IP address gets assigned to your Macbook by the router. But there are cases when the IP address assigned to your Macbook is ‘self assigned’ and that’s not a good thing. If you are a Mac User and you have set your Mac laptop to use a specific IP address then you can change it. However, if you don’t know what is self-assigned IP address and you want to know how to change it, then you are reading the right article.

Resolve "Self-Assigned IP" Errors for Apple Mac

Authored by: Support.com Tech Pro Team

1. Introduction: Apple Mac: Resolve Self-Assigned IP Address

One possible result of the inability to get online is that you have what is referred to as a self assigned IP address. This usually happens when your router (which normally provides you an IP address) does not provide you an IP address to talk to other computers.

Example of a Self Assigned IP Address

This guide will help you to troubleshoot self assigned IP addresses.

2. Network: Reboot

One of the main causes with the inability to get on the Internet is that your networking equipment could have malfunctioned. Sometimes performing a reboot will resolve this issue.

Your network may consist of one or more of the following networking devices.

This is the primary device used to get you on the Internet.

  • Has either a coaxial cable, fiber cable, or phone cord plugged into it.
  • Typically has 1 or 2 Ethernet ports which connect to a router.

This is an all-in-one device that has both a modem and a router built in. It is a primary device used to get you on the Internet.

  • Typically has 3 or 4 Ethernet ports which connect to a your computers and smart devices.
  • Typically has Wi-Fi built into it

This device allows you to connect multiple devices to your Internet connection using a single external IP address.

  • Typically has Wi-Fi built into it.

This device helps to extend the wired functionallity of devices by provuding your additional Ethernet ports.

  • These are typically plug and play.
  • This device is not a router.

AccessPoint

This device will provide wireless access to your existing network.

  • Used to extend the range of your network
  • Usually plugged into a router/gateway via Ethernet connection.

RangeExtender

This device will extend the range of your existing Wi-Fi network by rebroadcasting your Wi-Fi network.

  • Standalone device plugged into a power source.
  • Usually located 15-30 feet from the router.

Next we will want to power cycle the networking devices.

Modem / Gateway

  • Unplug the power from the device.
  • Wait 30 seconds.
  • Plug the power back into the device.
  • Wait for the device to go online.

Access Point / Range Extender

3. macos: restart.

  • From the menu bar across the top of the screen, select the Apple menu (1), then select Restart... (2).

Apple menu with Restart option selected. Screenshot.

Any unsaved work will be lost.

4. Network: Determine Connection Type

Next we need to know how your device connects to the Internet.

  • Wireless - You connect using a wireless router or access point.
  • Wired - You use an Ethernet cable plugged into your gateway/router/switch and the other end is plugged into your device.

TheRealNick said: So I regularly use my iPhone for internet access on my Mac. (Retina 5K, 27-inch Late 2015) I also plug in my Xbox through the ethernet port and share the connection. I've never really had an issue but yesterday I received the error "Ethernet has a self-assigned IP address and will not be able to connect to the internet..." I cannot seem to fix this. I tried plugging my laptop in instead of the Xbox and received the same message, so it is not just the Xbox. I also tried three different cables just to be sure it wasn't the cable, same message. Does anyone have any further ideas on how I can fix this? Big Sur is 11.1 11.4 and I don't know if its makes a difference but the iPhone is an XR running iOS 14.5.1 Many thanks!

The list on the left is a prioritized hierarchy of interfaces. The Mac will look for an internet connection beginning at the top interface and working down. Since you have an XBox at the top of the list that can’t provide internet access to your Mac, the message you see makes perfect sense. Drag iPhone USB above Ethernet and you should be fine.

Check your router or wireless access point: the DHCP function may not be working right. DHCP assigns IP addresses to downstream devices, like iPhones and Xboxes. If DHCP isn’t working, then your downstream devices will self-assign IP addresses. Try rebooting the router.

I would POWER DOWN everything (completely off, not just "a restart"): - Macs - Router(s) - ISP interface/modem Then, RE-power, in order: 1. ISP interface/modem 2. Router(s) 3. Macs.

We have managed to solve our problem of self-assigned IP addresses

when starting up an M1 Mac Mini.  The initial set-up used a Macbook

Air Time Machine backup as the source.  This source included an

Internet Security App that was later found is not compatible with M1

and may have been blocking all input / output from the network. As

well as not being able to get an IP address automatically even a

manually assigned address could not establish connectivity with the

router.  The solution was to start the Mini in Safe Mode and that

allowed a wifi connection to be established with an automatic IP

address.  We found that the ThunderBird App while not compatible with

M1 provided a prompt to download Rosetta 2.  With Rosetta 2 installed

the Mac Mini was rebooted and was still able to get an IP adddress

automatically.  We could then disable and uninstall the Internet

Security App. The lessons learned are firstly one should check

compatibility of apps that could potential block network traffic and

if necessary uninstall any internet security apps on the source before

using a backup to setup a new M1 machine.  Secondly Apple could make

it easier to provide Rosetta 2 as part of the MacOS intall on a new M1
