Wifi issues on El Capitan???

I have a early 2014 MacBook air and upgraded to El Capitan a few weeks ago but since updating I have been having wifi issues. When I try to connect it won't connect at all even though my iPad 2 and iPhone 6 connect just fine, also my wife's Macbook Air (same as mine) connects just fine. The only way I can fix the issue is by turning off the router and turning it back on. Before this issue the only problem I had with the wifi was when I would wake up my MBA the wifi would show it was connected but wouldn't connect to the internet and I would need to turn off the wifi then turn it back on and it would work fine. I tried to connect to my phones hotspot and it worked just fine.

Any help on this issue would be greatly appreciated!!!

Thanks in advance.

MacBook Air, OS X El Capitan (10.11)

Since this only happens your Mac, it may be corrupted network preferences.

Open the Finder. From the Finder menu bar click Go > Go to Folder

Type or copy paste the following:

/Library/Preferences/SystemConfiguration

Click Go then move all the files in the SystemConfiguration folder to the Trash.

Restart your Mac. See if that makes a difference.

Your Mac will generate a new SystemConfiguration folder for you.

When I tried this is said the files could not be moved as they were needed by the OS.
