I'll test this, I guess that it should indeed help.

This actually seems to be iwl3945 bug.

This is the tests I did:

1 . Upload / download from my desktop computer (connected via wired interface)
Speeds are rock solid 1.3 Mbytes/s in both directions

2. Then I tried to upload to my laptop (iwl3945)
Speeds were around 600 Kbytes/s, then after few minutes the ath5k dropped association, associated
again and transfer speed dropped below 64 Kbyte/s
(They didn't stall thought)

3. Then I reloaded the ath5k, it didn't help, 64 Kbyte/s again.

4. Then I tried to transfer files to desktop, 1.3 Mbytes/s again.

5. then tried the laptop, 64 Kbyte/s again

6. Then I reloaded the iwl3945 on laptop, and got 600 Kbytes/s.

It still isn't very clear who is responsible, but this is very fishy.
Maybe the ath5k shouldn't drop association, though.

600 Kbytes/s isn't good ether.

Also ath5k stopped working at all, when I did long test transfer between desktop and laptop, dmesg was full
of some strange message repeated, I haven't been able to reproduce that again, when I do, I will post that message.

In general, ath5k works nice here, big thanks to you for such great work.

Best regards,
Maxim Levitsky
