Package: linux-image-2.6.18-4-686
Version: 2.6.18.dfsg.1-11
Severity: normal
I was having problems with WPA-encrypted networks in heavy load
conditions, e.g. when transferring files from a local server.
Every minute I would be disconnected with the error messages

And after about 1 minute, the wireless reconnected again.
After googling a while, I found this page:
http://www.tuxyturvy.com/blog/index.php?/archives/23-Using-the-IPW3945-with-Linux,-WPA,-and-the-SMP-Kernel.html
That is exactly my setup, and my error. I don't know which ieee80211
version is included with the 2.6.18 kernel, but I'm experiencing this
problem, and there is one more comment mentioning 2.6.18

commit 4d1feabcbf41f875447a392015acd0796f57baf6
Author: Ulrich Kunitz <[EMAIL PROTECTED]>

[PATCH] zd1211rw: Call ieee80211_rx in tasklet
The driver called ieee80211_rx in hardware interrupt context. This has
been against the intention of the ieee80211_rx function. It caused a bug
in the crypto routines used by WPA. This patch calls ieee80211_rx in a
tasklet.

That could be the relevant changeset, I don't know. There are some more 80211
related patches that could be relevant.
Anyway, not having reliable networking is a bigger issue for me...
