Wifi disconnect after random time

Postby derderder » 2015-09-16 20:33

I have strange problem with my wireless connection.
When I boot my computer, I can connect to my wireless network normally. After a random time between 2 and 20 minutes, I am disconnect and cannot reconnect to any wireless network
I have no problems in Windows and Android.

I use the broadcom-sta-dkms driver and the power management is disabled.
