[Bug 1492850] Re: Dell pro venue 11 - No wireless connections after sleep
stef.baly, given the results of how via upstart it works, but systemd
suspend doesn't work based on the method one initiates suspend, I've
added a systemd task to this report for review.
** Also affects: systemd (Ubuntu)
Importance: Undecided
Status: New
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed

Title:
Dell pro venue 11 - No wireless connections after sleep
Status in linux package in Ubuntu:
Confirmed
Status in systemd package in Ubuntu:
New
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_MODULES="$SUSPEND_MODULES iwlwifi" without any effect.
sudo service network-manager restart doesn't work too !
Before suspend
