I'm using freya and had wlan without any problem since weeks/months.

Today I installed the printer driver for a Canon Pixma MG2950. Because I can't set up this printer for wireless printing in linux I started Win8 and set it up there with the cd rom from the printer.

In this setup there were a notice that the network is shutting down for a short time (or something like that)...

Don't know if this has something to do with my problem but since that time when I start freya again I see shortly after the desktop is there a bubble which states "the network gots shut down - offline". When I click the WLAN icon all entries there are grayed out :(

(connecting a cable still works and I get a working connection)

Here are some debugging infos/outputs from my system http://pastebin.com/ihTej3VL

Try loading the driver

sudo modprobe -v ath9k

and then restart the wireless network

sudo service network-manager restart

If restarting the network manager didn't work, try rebooting the machine.
