How To Fix Common Connection Wi-Fi Issue: Self-assigned IP on MacBook
In this article, you will find some solutions that will help you fix Wi-Fi issue on the MacBook. We use MacBook as one of mobile productivity devices. Sometimes, in a new place, we have to connect our MacBook to a local Wi-Fi, so that we can access the Internet.

There’s a time when Wi-Fi is already connected , but we still cannot access the Internet while our friends are doing it normally with their MacBook. In such a case, check your MacBook’s Wi-Fi icon first on a menu bar.
If you see the exclamation mark ( ! ) on Wi-Fi icon in the menu bar as you can see on the picture above, it says that there’s a network issue. Click the Wi-Fi icon, and you will probably see this.
How To Fix Common Connection Wi-Fi Issue: Self-assigned IP on MacBook
No Internet Connection issue can be caused by many things, and one of those is self-assigned IP issue. We are going to troubleshoot and fix the self-assigned IP on MacBook.
I’m going to share one solution for this issue. If you are using Mac OS X 10.5 or later and facing this issue, you can try this.
The first thing: Check your Network Preferences
Click Apple menu > System preferences > Network
In this part you have to make sure that Location (1) is on Automatic option as you see on the picture below, then click Advanced (2).
After you click Advanced (2), a new window will appear as you see in the picture below. Click TCP/IP tab and you will see this window.
You have to notice two things, Configure IPv4 (1) and Router (2). If you have the main problem where Configure IPv4 has been set at Using DHCP, but the Router is not set by any IP, then try this following steps to solve that issue.
Steps for troubleshooting
- Click Finder Icon, then in Menu Bar Click Go > Go to Folder
- After you click Go to Folder, type : /Library/Preferences/SystemConfiguration/
Notice: It will reset all your network configuration. If you don’t have a problem with losing your network configuration, you can continue to the next steps.
- Delete the files that I highlighted in the picture below. You will be asked for your admin password.
- Restart you MacBook. After you log in, try to connect to the same Wi-Fi. Check and make sure that the Router is filled by Router IP in Advanced window.
Amazing! It worked! Thank you!
I tried this but when I restarted my computer and returned to system configuration the files I deleted were back. Even though I moved to bin and deleted from the bin. So frustrating!
it workssss. thanks a lot
Eres the* mejor!!!! Gracias
<3
It works for the first few seconds, the router IP would quickly disappear again after that. How to prevent this?
The router doesn’t come on
This worked for me. My question is how to prevent this from happening again?
Merci beaucoup j’ai perdu beaucoup de temps avec les autres tutos mais la c’est parfait avec le votre
Thank you so much ! Was struggling and tried these steps . I didn’t have network identification file and I followed one comment here and deleted eap configuration file instead and it worked
Do u just have to move the files to trash or delete them immediately??
For those without “com.apple.network.identification.plist”, there is a similar file called “com.apple.network.eapolclient.configuration.plist”.
I deleted that (in addition to the other files highlighted) and it worked for me.
It says file not found . I am never spending any money on apple products again . This is causing me great stress and too much time. Macbook is not even that good to be honest. Overpriced junk. I need to use my own damn internet on my own laptop .
This didn’t work. I’ve tried several times
Thank you so much for this information.
Omg!!! Thanks so much. I was going crazy trying to figure it out!
EPIC!!!!!! Fixed it
virgin superhub : Solved For me
network settings go to Hardware change Mac address configuration from manual To automatic
Not worked for me
It’s not working…I have tried all methods in here but my laptop still cannot connect to a certain wifi, but all other devices work well and my laptop can use all other wifi well…
Yes unfortunately I am also missing that particular file / line and am unsure if it will work or not doing this procedure.
Not working here either
It’s not working because I don’t have com.apple.network.identification.plist in my folder ?
awesome! it worked for me too!
Thank you!!!!!!! It worked
Tried as advised, not working
Hey! what if com.apple.network.identification.plist is not in this folder?
I have the same issue!
Me too
Ir seems it is because we have a later OS and works different. There is other file that looks like that one but no exactly same name. Deleted that and worked for me
