Since I updated ubuntu to 14.04 version, my wifi is unstable and slow. I
did wifi tests and sometimes the connection stabilze but in some minutes
(sometimes 30minutes, or 8minutes, or more, or less) the wifi network
disconnects. I need to turn the wireless adapter off and on again to
reconnect.
When I tested my wifi speed (in some websites that measure this), I see
that the download proccess is very unstable. Sometimes go to the maximum
speed and after stops, and go slow, and go fast... very unstable!
I dont know if this is a network problem or kernel problem, but I can
confirm that this just happens on new ubuntu version (14.04) - I have
other notebook with other distro and works fine, and my Android device
has a stable wifi connection.
