Title:
Wifi (wlan) slow and unstable when updated to 14.04
Status in “network-manager” package in Ubuntu:
New
Bug description:
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.
