As the title says, since upgrading to 14.04, my wifi connection has been periodically hanging then dropping every 10min to hour. It will not reconnect unless I bring the adapter down and back up. So far I've tried upgrading the firmware for the adapter, making sure power management is off.
Here is relevant stuff. Thanks in advance for any help!
