Q: Wifi problem since the 10.11.6 OS X El Capitan Update

I've been having trouble with wifi on my MacBook Air. I've had it for two years and recently I updated to the latest el capitan version 10.11.6. Ever since then, I couldn't connect to wifi. I tried to boot it in safe mode and then wifi works. It seems that wifi only works when I'm in safe mode. It's really inconvenient that I have to boot it in safe mode if I want to use wifi. I've tried everything. How can I fix this problem? I don't know what the problem is.

MacBook Air (13-inch, Early 2014), OS X El Capitan (10.11.6)

    Hi,

     

    There are a lot of things we can do here,

     

    First, I would like you to remove the Wifi Profile from system preferences and then re-add a new one and then restart.

    Second, In the User library which is located via finder-Go-Library and then pull and remove these files:

    /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist

    /Library/Preferences/SystemConfiguration/preferences.plist

    And then restart,

     

    good luck.

    Hmm I also tried this but it doesn't work for me either. Other Apple computers with legacy OS still connect seamlessly to my wifi router, as do iPad and iPhones with current IOS. I'm sure it's just one setting in system preferences that has changed, but which one?
