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).

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

  1. 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!

  2. 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

  3. 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.

  4. 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 .

  5. 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…

  6. Yes unfortunately I am also missing that particular file / line and am unsure if it will work or not doing this procedure.

        1. 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
