XPS 13 9350 wifi and battery problems

Hi wveryone,

as many of us, in the update to the last kernel 3.19.0-65 I lost my wifi, I solved the problem changing the drivers in the page "additional drivers" to the iwlwifi type for the Intel 8260 card.

Everything now works fine for the wifi BUT the battery life is really reduced and I lost 2-3 hours.

I tried then to select the other driver for the wifi but inthis case it was not workins

Can someone plz help me? a good starting point would be that you write which wifi driver are you using and if you experinced the same

thanks

Lorenzo
