Public bug reported: After a random amount of time, wifi disconnects and any attempts to reconnect fail. Happens regardless of having had the computer suspended.
dmesg says "chip reset failed", "unable to reset channel", "unable to set channel", "failed to stop TX DMA", "DMA failed to stop in 10 ms", "could not stop RX". Reboot always fixes. Turning wlan adapter power saving off also fixes. When the following commands at run after startup, the problems never appears: sudo iwconfig wlan0 power off sudo iw dev wlan0 set power_save off This issue is also filed at redhat bugzilla: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=815377 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: linux-image-3.2.0-30-generic 3.2.0-30.48 ProcVersionSignature: Ubuntu 3.2.0-30.48-generic 3.2.27 Uname: Linux 3.2.0-30-generic i686 AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24.
