I'm using Linux Mint 14 on a Novatech N1408 laptop which has an Atheros network card and uses the ath9k driver. WiFi works fine apart from resuming the laptop from being suspended, at which point I am unable to get WiFi working again until I've rebooted. It still seems to work if I hibernate the laptop, just not if I suspend it.
I have tried a few different things that I have seen suggested, including having a script with "sudo modprobe-r ath9k" before suspension and then "sudo modprobe ath9k" on resume, but this does not bring the connection back for me, neither does entering it manually into the terminal.
Any help would be greatly appreciated!
