Just to confirm:
Ubuntu 10.04, 2.6.32-22-generic #36-Ubuntu SMP Thu Jun 3 19:31:57 UTC 2010 x86_64 GNU/Linux
I have the same, still:
$ dmesg | grep rt

what I have is a TP-Link TL-WN321G.
So what it does, are frequently disconnects, and mostly some crap visible in ping:
4.5 ms
121 ms
1247 ms
6442 ms
5873 ms
5227 ms
1174 ms
... and so forth; with a signal strength of 88%, while just another box does pretty well.
If there is anything I can do to help getting this bug out of the kernel, please, rope in my help!
