Title:
8086:008a Centrino 1030/iwlwifi disconnects ~30 s from N access points
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Just got a new computer with a centrino N 1030 wireless card. Ubuntu
uses the iwlwifi driver with it.
When I am connected to an 802.11N access point, the wireless stops
working about every 30 seconds, for about 30 seconds. The connection
doesn't disconnect, it just stops working.
WORKAROUND: If I'm on a G access point, or force a G connection,
everything is fine.
