Wireless problems on Acer Aspire One using Ubuntu Karmic

[Gavin McCullagh <gmccullagh gmail com>]

Hi,

I've reported a bug on Ubuntu's launchpad but as time is pressing toward
the release, I thought I'd bring it up here.

https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/433720

When I connect to my wireless access point here (since upgrading to
Karmic), the network manager shows a successful connection and then after a
couple of seconds, I get disconnected.  This makes wifi moreorless
impossible to use.  It's not clear to me if this is a NM problem or
something else.  Could someone give me an indication of this?  

dmesg gives me the following information:

[  122.156114] wlan0: associated

Is there other information I should provide?
