Q: Wifi not configured

Hi, basically I had the login problem for app store.

In internet It said to delete the networkinterference.plist file from systemconfiduration folder and then restart.

After I did it now I cannot connect to the wifi. It's saying that wifi is not configured.

In network menu bar, wifi is off thunderbolt bridge is some connected.

I don't know what should I do to connect to wifi again. Please help me

MacBook Air, OS X Yosemite (10.10.5), null

    Try the following on your Mac in order, until (hopefully) resolved:

     

    1. Create a New User Account
      • System Preferences > Accounts
      • Click "+" to add a new account.
      • Log off, and then, log back on with the new user account.
      • Try connecting to a Wi-Fi network with your Mac's AirPort.
      • If this resolves the problem, there may be something amiss with your current profile and will require further troubleshooting.
      • If this does not resolve the problem, go ahead and log back into your normal account and go on to the next three steps.
    2. Delete AirPort Keychain Entries
      • Launch the "Keychain Access" application located in Applications/Utilities.
      • In the windows on the left side: Select login for Keychains and "Passwords" for Category.
      • Click on the "Kind" filter at the top, and look for any "AirPort network password" entries...and delete them.
      • Close Keychain Access.
    3. Delete Preferred Network(s)
      • System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
      • Delete all entries under "Preferred Networks."
      • Click on OK.
    4. Add Preferred Network(s)
      • System Preferences > Network > Wi-Fi > Advanced > Wi-Fi tab
      • Add the preferred network(s) using the "+" button.
      • Click on OK.
      • Restart or log out, and then, back in.
        • If it works, then you are done.
        • If not, go on to the next step.
    5. Move System Configuration Files

    In Finder, go to /Macintosh HD/Library/Preferences/

      • Move (not copy) the entire SystemConfiguration folder to the OS X desktop.
      • Restart the computer.
      • Verify that you have connectivity.

    Actually by mistake I deleted the wifi in the network while i was trying out everything and tried to add new wifi but failed. I tried the first solution but it was not the problem of accounts. Do I still have any hope to resolve it?

    Possibly. I suggest trying to add the Wi-Fi connector again.

     

    • Go to System Preferences > Network
    • Unlock if required.
    • Click on the plus "+" sign to add a network connector.
    • For Interface, choose: Wi-Fi
    • For Service Name, choose: Wi-Fi
    • Click on Create.

    You should now have the Wi-Fi connector back.
