Title:
Wi-Fi connection to hidden wireless networks broken after 20 minutes
or so -- Atheros AR9285 ath9k
Status in “network-manager” package in Ubuntu:
Incomplete
Bug description:
Binary package hint: network-manager
I'm using hidden wireless network on my DIR-320 router and connecting to it
from Asus K50IN. The connection establishes fine, but after some time (from 10
to 30 minutes) wlan adapter looses network. NM displays that i'm connected and
wlan0 still has the same IP, but i can't connect even to the router. Stoping
and starting the connection fixes the problem for a while...
