Hello,
I am having troubles with wifi since my clean install of El Capitan 10.11.4 on my MacBook Pro 9,1 (15" mi 2012).
I can connect sometimes to my wifi router but the connection is not staying. A ping in the Terminal show regularily no route to host or very long response time.
When I try to disconnect and connect again to the wifi, I can't (impossible to connect).
I tried on another router, or with my phone connection shared via wifi, same behavior.
I tried several things to fix the problem:
> reset PRAM
> reset SMC
> deleted networking preferences and recreated them
> deleted files in /Library/Preferences/SystemConfiguration/, rebooted and try to connect again (solves the problem temporarily)
> disabled bluetooth
> disabled ADWL
I am desperate, I don't know what to do else to fix my problem !
Any advice ?
