[ubuntu] Atheros AR9285 Issues

view full story

http://ubuntuforums.org – I've recently installed Ubuntu 12.10 and have been having intermittent issues with wireless. Often I'll wake my machine up and will have no network connectivity despite the wireless menu showing that I am indeed connected. Fixing this normally involves having to reconnect (sometimes having to repeat this step multiple times) or typically having to restart my system entirely. Running lshw -C network tells me that my wireless interface is an Atheros AR9285. (Hardware)
