Comment 3 for bug 291760

I can confirm this bug. I get the same problem, i.e. regular loss of connection every two minutes or so due to roaming to "(none)" and back to my preferred network.

I'm running

ubuntu 8.10
network-manager 0.7~~svn20081018t105859-0ubuntu1

This problem started to occur after I installed

linux-backports-modules-2.6.27-9-generic

as a means to address the wifi related kernel panic bug #276990.

I'm using an atheros based 802.11abg card.

Detailed logs follows.
