self assigned ip address mac mini

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.

Use DHCP or a manual IP address on Mac

An Internet Protocol (IP) address is a number that identifies each computer across the internet or a network. When you connect to the internet or an IP network, your computer needs an IP address.

Your IP address can be provided in two main ways:

Automatically: Your computer is assigned an address using Dynamic Host Configuration Protocol (DHCP).

Manually: Your ISP or network administrator gives you an IP address, and you enter it in Network settings.

Follow these steps to enter your IP address or have it assigned automatically.

Open Network settings for me

Click the network connection you want to use on the right, then click Details.

Click TCP/IP.

Click the Configure IPv4 pop-up menu, then choose an option:

If your address is assigned automatically, choose Using DHCP.

If your ISP or administrator gave you an IP address, choose Manually, then enter the address in the IP address field. If your ISP gave you additional information such as the subnet mask and router, enter those values in the labeled fields.

self assigned ip address mac mini

Note: Most IP addresses are IPv4 addresses, which look like a series of numbers separated by three periods, similar to this: 123.45.67.89. If you received an IP address that’s a longer series of numbers and letters, divided by seven colons (for example, fa80:0000:0000:0123:0203:93ee:ef5b:44a0), it’s a different type of IP address called IPv6. To enter an IPv6 address, click the Configure IPv6 pop-up menu, choose Manually, then enter your IPv6 address.

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

Weird recurring problem: Every day for the past few days, at a certain point in the evening (around 10-11 PM), my M1 Mac Mini loses its connection to the network over both ethernet and wifi. Both services in the Network panel in System Preferences say “self assigned ip address”. A reboot solves the problem, but it comes back the next day.

None of the other devices on my home network – wired or wireless – have this issue.

The ethernet port on the Mac is connected directly to a TP-link modem-router. Wifi is to a TP-link Deco mesh network (main Deco is M5 unit sitting right next to the Mac Mini and connected to the router via ethernet cable).

Given this problem is only on the Mac Mini and also affects both the wired and wireless networks (which are 2 different devices at the other end), I assume this is a Mac Mini problem and not a network problem.

Is it exact the same time, or is it around a time-frame? Is there, or can you activate, a protocol on the Router, to see what happens before and after the disconnection? What is the weather like in your area? Is there a daily reconnect of the router with the external network? Some ISP require that once a day.

UPDATE: The problem was not happening at the exact same time every day, but at around the same time. It only affected one of the 10-15 devices on the network, and it affected that device on both the wired and wireless connection. The weather is consistent (hot and dry). The router does not reconnect to the ISP on any schedule.

I figured out that the problem was somehow connected to the renewal of the DHCP lease. The IP address would switch to “self assigned” at the time the lease was supposed to renew. It wasn’t the exact same time every day, because sometimes I would not notice the problem right away. When I did notice it, I would reboot the computer, which would temporarily solve the problem by getting a new IP address from the router, which would reset the lease renewal to 24 hours later than that moment.

I tried clicking the “renew DHCP lease” button in Network Settings, but that did not seem to do anything as long as the IP address was self assigned. If the lease was still active when I manually renewed, it would renew for 24 hours, which would just delay the inevitable (unless I would remember to manually renew every <24 hours).

What did seem to solve the problem was switching “Configure IPv4” of both Ethernet and Wi-Fi to “Using DHCP with manual address” and then typing in a unique IP address for each (choosing a number within the designated range which was not currently in use by another machine on the network).

It’s been several days now with no problems.

Is there any downside to using manual IP addresses?

Not on a Mac mini. I actually prefer knowing the IP addresses of my desktop devices. Good troubleshooting and solution!

Not to my knowledge. I am setting up my networks always in that way, what keeps me also from searching, if I need to address a device by its IP. I am doing this since the beginning of private networks, so somewhat since 20-30 years now, with zero problems (that I could blame this setting for!) at all.

While there is no downside to a manual IP address, if possible, you should set it on the ROUTER.

This is done by selecting the MAC address of the mac mini network adapter and assigning a static ip. (Not all routers support this)

Just ensure it is NOT in your DHCP range.

To @Ulli ’s and @Jezmund_Berserker points, I assign all devices on my home network a static ip address.

Why should it not be in the DHCP Range? Specially if you set it up within the router?

You want to be able to see WHICH addresses are “dynamic” DHCP leases.

SO, if you have “dynamic” DHCP 192.168.1.50 - 192.168.1.99 and everything else “trusted” with static IP addresses, you can easily identify the outsiders…

Ah, ok. My router shows me, if he has a “dynamic” address. And I don´t have any, so no need for that trick anyway.

Yes. Plus having them managed from the router, you can leave your Mac/iPhone/iPad (whatever) set to DHCP and if you ever connect to another network, you won’t be pulling your hair out for an hour because you forgot that you have YOUR network address set statically.

Only if you are not careful. Suppose at a moment when your device with a manual IP address is down a separate new device connects to your network and requests an IP address from the router. Because the manual address is not being used at that time, the router could assign it to the new device. Then, when your manual device starts up, it encounters an error as the IP address is not available.

The solutions to avoid this have already been mentioned.

  • Assign the manual IP address at the router, not the device. That way, the router will never assign that IP address to any other device.
  • Use an address outside of the DHCP range. Again, this ensures that the router will never assign it to any other device.

Using both provides the best insurance. Using option 2 only could still result in a conflict if two devices have the same IP address manually set on the device. However, with option 1, the router will only allow you to assign an IP address to one MAC address (used to identify each device as unique) at a time. Therefore, there are no conflicts and all manual IP addresses are managed at one location.

Thats a very conscientious approaching, but that’s not really how IP address assignment works. Being down for a moment doesn’t put you at risk of conflicts.

In a home setting especially, there is no issue with assigning a static IP from the device.

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

arthankamal's user avatar

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.

I'm ure you figured this out already, but I just spent 2 hours going through this issue and this is the BEST fix I came up with, seems to have stopped my issues no matter how much I move from place to place.

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.

I'm a couple of years late but in case anyone finds this thread from a search, I hope this might help:

I got the 'self-assigned IP' problem after reversing the order of two Airports - base vs extension.

At first, I tried tips that helped others - trashing various prefs, re-setting the base station, manually entering random DHCP client numbers, deleting networks, keychains, etc - but no luck.

I then tried the following:

- turned Wi-Fi off on all Macs

- unplugged the 'extension' Airport

- reset the base station Airport (paper clip/flashing orange light routine)

- reconfigured the network with Airport Utility (using the same network name and password as before)

- turned Wifi back on and - bingo - both - Macs connected to Wifi again

- I then restarted and reconnected the 'extension' Airport.

I can't say which step(s) fixed it but my guess is that it may have been a combo of simplifying the network to just the base station, then resetting that, and then rebuilding the network.

Read through several of the replies, and noted with interest that the IP address "169.xxx.xxx.xxx" was self-assigned.

I ended up re-starting the modem and the Ethernet connection came up correctly, but then the Wi-Fi address was the self-assigned "169.xxx.xxx.xxx". Hmm. Re-started the Wi-Fi part of the modem/router and it was fixed. Really weird.

I'd just put in some power-line adapters to try out, and wondered if that had really messed things up. Good to know they hadn't -- except that one of the Macs hadn't been connected via Ethernet for some time. The connection worked last night, but not this morning. Glad things are back up and running.

I know this thread is super old but if anyone is still having this problem, like I did I finally solved my issue! I tried everything in this thread from manually entering the IP address, rebooting my computer, etc. LITERALLY everything. I finally called my ISP (TWC/Spectrum) and told him my issue and the customer service guy figured out that our modem was receiving the wrong information from the servers, resulting in the self-assigned IP address. He rebooted the modem manually and worked some magic and I was instantly online!!!! Hope this helps someone

Happened on my wife's MacBook Pro running 10.12.6---Self-assigned IP on WiFi and Ethernet. Other Apple devices in the house connected with no problem. I tried all fixes in this thread. Nothing worked. I could establish WiFi and Ethernet communication to the internal network (manual IP address), but not to the Internet. Rebooting and resetting ISP modem did not work. Took it to the Apple Store. The MBP connected to their Ethernet, but not to their WiFi. The GB-worker noodled awhile, no solution. Finally, they loaded a new system, then WiFi and Ethernet connected to Internet. Later, at home, used Time Machine to restore the MBP to last working version. WiFi and Ethernet to Internet have been working ever since. Would just using Time Machine at the outset have worked? Maybe.

Apr 16, 2012 8:42 PM in response to joepark14

I had this happen to me twice and the solution for me was to delete the wifi network and keychain password.

The first time i fixed it by restoring from Time Machine which took a long time. I also tried the renew DHCP, delete com.alf.plist etc to no avail. The second time I found a better solution from someone on this forum:

Go to Network Settings

Turn Airport Off

Click Advanced tab

Select my wifi network and hit minus sign to delete

Click apply

Go to Keychain access in Applications/Utilities

Find your network name in the list and delete that password login

Then go back to Network settings and turn airport back on

Click Advanced

Click plus sign then Show Networks

Choose your network and re-enter your password

Click Apply

Then airport should work again, this is what fixed it for me.

All the best
