Comment 16 for bug 425455

I've got the same issue with an Karmic upgrade from Jaunty on my Dell Latitude D630 laptop. In Jaunty wireless worked fine, and in Karmic it fails after 30 secs to a minute or two. Here's my 802.11 info:

Network controller: Intel Corporation PRO/Wireless 4965 AG or AGN [Kedron] Network Connection (rev 61)

and the output from dmesg:
