Comment 23 for bug 340418

I think that everyone here that is having the issue should report which access point they are having the issue with and whether the problem can be replicated with a different access point. It seems that quite a few people that are having this issue (myself included) are using the Linksys WRT54GL router, and some have reported that the issue goes away when using a different access point.

I'm using an Intel 3945ABG card in my Dell XPS m1330 in Karmic (Kernel 2.6.31-17-generic) and I'm having a similar issue. For the first 20-30 minutes after the connection is established, it works fine at a full 7mbit. However, after that point, it begins to degrade until I rmmod/modprobe iwl3945...and the cycle continues. I haven't noticed the issue with a Ubiquiti NS2L AP, so I'm starting to wonder if this is related to the WRT54GL.
