Debugging iwlagn intermittent connectivity issue

[Paul Jones <pajones gmail com>]

Hi,
   I was hoping to get some help with a intermittent connectivity
issue using Ubuntu Intrepid (8.10). My wireless connection (iwlagn)
seems to fail intermittently for 15-30s at a time as frequently as
every couple of minutes. NetworkManager doesn't report that the
connection has failed and there doesn't seem to be anything of note in
syslog or wpa_supplicant.log.

   I have no idea where this bug could be located and I would like
some help with debugging. I have experienced the bug using three
difference AP. I haven't eliminated a hardware issue however, as I've
only run this laptop using Intrepid. But hardware seems unlikely as
the problem is alleviated by rebooting. I have experienced the bug
with every Intrepid kernel that has been released thus far. The bug
seems to occur mainly when the wireless network is under load. For
instance, when I'm streaming videos off of Hulu.

   I have posted a bug report here
(https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/384924).
It should contain much of the relevant information.

   I appreciate any help your experience can bring. Thanks for your time

Paul
