My Kubuntu was working well until I think a day ago, and suddenly I don't have access to Wi-Fi. I've tried turning on the connection via the Connection editor but the box was grayed out.
After looking for solutions via various sites i came up with this answer to



lshw -c network


as following:



*-network UNCLAIMED
description: Network controller
product: AR9285 Wireless Network Adapter (PCI-Express)
vendor: Qualcomm Atheros
physical id: 0
bus info: pci@0000:03:00.0
version: 01
width: 64 bits
clock: 33MHZ
capabilities: bus_master cap_list
configuration: latency=0
resources: memory:f0500000-f050ffff


I understood that this problem caused because i lack a driver, but the thing is, everything was working fine about a day ago.

          Okay after searching some more, and focusing on the driver problem i came up with this:



           echo "options ath9k nohwcrypt=1" | sudo tee /etc/modprobe.d/ath9k.conf
          sudo modprobe -rfv ath9k
          sudo modprobe -v ath9k


          I have no idea what it does, but it worked!
