[Bug 1253997] Re: WiFi randomly disconnects
Update. I had to remove v3.12 trusty kernel. The system becomes quite unusable.
So far, only v3.11.0-12 is usable for more than 1 hour.
There is something definitely wrong in the rt3290 support.

Title:
WiFi randomly disconnects
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Since upgrading to 13.10 the WiFi support has been shaky. Frequent connection drops and unstable network-manager. Only solution is a reboot, often more than one.
I cannot connect to a WiFi network using authentication but WEP (any other authentication method gives instantaneous loss of connectivity).
