Bug#800721:
Wifi was working stable for a few days now, even when using standby and let
running Laptop 8h in Idle.
But today, after 1.5h beeing Idle and screen of, when coming back, Wifi was not
working. Waiting 3 mins as before does not help and I needed to disable and
enable Wifi adapter in GNOME-Networkmanager to enable Internet and local
network-access again.
Here is one output from iwconfig in terminal while wifi was not working:
"
eth0 no wireless extensions.
wlan0 IEEE 802.11abgn ESSID:"TEST"
Mode:Managed Frequency:2.412 GHz Access Point: 34:31:C4:66:1F:56

Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:1 Invalid misc:548 Missed beacon:0
wwan0 no wireless extensions.
lo no wireless extensions.
"
Then I did another output in terminal after disable and enable WIFI adapter:
"
eth0 no wireless extensions.
wlan0 IEEE 802.11abgn ESSID:"TEST"
Mode:Managed Frequency:2.412 GHz Access Point: 34:31:C4:66:1F:56

Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0

lo no wireless extensions.
"
In both cases Network is connected but in first case it was not working.
Maybe the output of lspci -vvnn also helps:
