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.
