Bug Description
This on a fully updated Lucid amd64 system:
My Intel Pro/Wireless 4965 AG or AGN suddenly stopped working after an upgrade to the generic 2.6.32-17 kernel. It used to work flawlessly, with the iwlagn module, up until (and including) 2.6.32-16. It seems NetworkManager thinks there's still a connection, but there really isn't. Disconnecting and reconnecting, I can sometimes get it to work again, but only for a few seconds - sometimes even fractions of a second, it seems. Also, this is easily reproducible: it happens whenever I boot into the 2.6.32-17 generic 64-bit kernel.
A few details:

I'm having the same issue. I have a similar set up too. Using Ubuntu Lucid 64bit on HP dv6000 series laptop with Intel 4965 AGN. Wireless worked fine in 2.6.32-16 and once I updated to 2.6.32-17 - no wireless. The wireless icon at the top says it is connect to my LAN but you cannot access any web pages or devices on the network. Also, I noticed that it even has trouble displaying the home folder in Nautilus - seems very slow. I have to boot into 2.6.32-16.
