Bug#718477: iwlwifi: failed to insert Dummy STA entry for the AP
Package: src:linux
Version: 3.2.46-1
Severity: important
After some hours working correctly, the system is disconnected
from the wireless network and never connecting again until reboot
or running ifdown/ifup. That was happening every day.
The problem is fixed after installing kernel 3.4.55-030455 from
ubuntu kernel-ppa:
http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4.55-quantal/
