I m experiencing a problem with my wifi adapter. My network adapter is
atheros ar9485.
I am using debian jessie with kernel 3.16.0-4 and ath9k as a driver.
When my laptop boots, I have connectivity to wifi networks. After a while I
loose connection and I cannot connect any more, as it appears that wlan0
does not work.
I have used both gnome-network-manager and wicd and they both report
something like "Could not find any wireless networks".
Has anybody experienced the same problem, or has any idea about what might
be wrong?
