Bug Description
I try for a long time to set-up the wifi for my dell pro venue 11 v7130 (wifi chipset Intel Corporation Wireless 7260). The wifi connection is perfect until the computer is suspend. After a suspend, even activating the wifi from network manager is impossible. After suspend even an exit doesn't reconnect to the wifi connection. It seems that the wifi chipset is off and it's impossible to wake up.
Recently 15.04 has been update to 4.2 RC8. Nothing new !
A file unload_modules has been created.
/etc/pm/config.d with SUSPEND_
sudo service network-manager restart doesn't work too !
Before suspend
