OK - I've got some good news and some bad news. The good new is that I created a usb key of Jaunty alpha 4 to test, and as far as I could tell, the problem did not occur. My wireless connection did drop out periodically, but that actually *did* seem like a driver issue (when it died, it went completely out, and it was intermittent. You could set your watch by the problem I'm having in intrepid.) The bad news is that, in the interest of science, I installed the latest jaunty packages of network-manager, network-manager-gnome, wpasupplicant, and a handful of other packages I needed to satisfy dependencies on my intrepid setup. Unfortunately, the problem seems to still occur. I even did remove --purge on the old packages before installing the new ones. In other news, I check my friend's setup, and she has the same problem, but she is using the broadcom wl driver (i'm using intel iwl3945), and her setup was a fresh intrepid install from 2 months ago.
So, this is really confusing - the fact that I'm running most of the jaunty software makes it seem like a driver issue, but the problem occurs across drivers. Could it be a bug further down in the kernel wireless stack? Any other ideas on how to debug this?
