Got a new router (Netgear DGN2200) and wireless performance has been woeful, with disconnection fits happening several times a day - it disconnects out of the blue, and then fails to connect indefinitely - saying authentication timed out, or the firmware crashes and etc.

Here is a system log demonstrating the frequency of the issue: http://paste.ubuntu.com/705613/

Does anyone have any ideas? Launchpad unfortunately has not been helpful.

My wireless card is a mobile one: Network controller [0280]: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection [8086:4229] (rev 61)

I've found that killing wpa_supplicant seems to help stop it from looping like that.
