[ubuntu] Acer Aspire V3-571G Unreliable Wireless

view story

http://ubuntuforums.org – Hello All, I've just installed the x64 Desktop edition of 12.04 on my Acer Aspire V3 571G. The wireless does connect, though it can take a while. The problem is the wireless only stays connected for 45 minutes max. before it drops out, and then it continually 'reconnects' (never actually connecting to the network) until I either switch between a few networks or turn wireless off and on again. I'm using the ath9k driver that Ubuntu provides, and (although it shouldn't make a difference) GNOME3. Is there a more stable wireless driver available that I could use? Regards, Ben. (Hardware)
