My laptop is currently having other technical issues (video card is bad), but I'll attempt to give as much info as I can.

I started having this issue with kernel 2.6.27-7, and no kernel version since has worked properly for me. See my bug report (https://bugs.launchpad.net/ubuntu/+source/linux/+bug/303802) for additional logs and whatnot. So far, the kernel versions I have tried this with have been:

Ubuntu 2.6.27-7.15-generic
Ubuntu 2.6.27-7.16-generic
Ubuntu 2.6.27-9.19-generic
Ubuntu 2.6.27-11.22-generic
Various Ubuntu 2.6.28 iterations in Jaunty
2.6.28.10-amaterasu (my own custom build, with the config files copied from the prepackaged Ubuntu builds and slightly modified)

The 2.6.27 kernels were tested with BOTH the in-kernel *and* backports modules, both with no resolution. I apologize for not keeping track of the exact versions of 2.6.28 that I had issues with...but I know I was using the in-kernel modules. I also tried removing the modules, and downloading them manually from the ipw2200 website and setting them up manually. The setup worked, but the problem still persisted.

As for a relationship between heat and all of this, I doubt it has a bearing on it. My laptop's processor runs fairly hot (around the 52C area when I'm doing intensive graphics stuff...or playing flash videos), but I have noticed no correlation between that and my card working better/worse.

As I said in my previous comment, using Wicd has been my personal workaround, just like Stian has found. Using NetworkManager honestly appears to be the problem, or part of the problem, after Ubuntu kernel version 2.6.27. It's important to note that the problem occurs with the Ubuntu packages, because I have used Debian with their kernel and NM packages and had no problems. Unfortunately, I do not have any logs or additional information from my Debian install, so I do not know what versions of those packages I tried.

Also, I've found quite a lot of other bugs that may or may not be related to this one. If anyone wants to sift through additional information in those bugs, they may or may not find something useful.

Lastly, in bug 303802, Bryan Wu has asked if everyone can test the latest versions of Karmic to see if the bug is still present. I cannot test, as my laptop is not currently in my possession, however I hope others can. Images for testing are available at http://cdimage.ubuntu.com/daily-live/current/. If the bug is present, please run "apport-collect -p linux <bug #>" to gather and attach updated bug information.
