Title:
Wireless Network Connection Randomly Dropped
Status in “network-manager” package in Ubuntu:
New
Bug description:
Every wireless network connection made is disconnected at a random
time for no clear reason at all. Another issue that may be related is
that DNS is randomly cut off with no clear reason as to why it occurs,
although it occurs less frequently than the issue described above.
Using TP-Link TL-WN321G with Ubuntu 12.04. This is a serious issue as
it nearly makes it impossible to do anything over a wireless LAN (incl
using the Internet).
