Hi, sorry for cross-posting, but this issue really spans both iwl3945 and ath5k.
I have two laptops (acer 5720, and aspire one) and I see some strange speed issues. I initially blamed iwl3945, then thought it got fixed, but now I have ath5k, and speeds are low and I suspect that both drivers has bugs regarding to speed. Walter Francis, once reported similar issue, so I cc'ed him too. He says that 2.6.25 works fine for iwl3945. I'll test this, and bisect if necessary. So here it goes: System setup: a wired desktop connected to a router, I call it just router as wired connection there is 100 Mbits/s and this can't be the bottleneck. two laptops, both are close to the router, signal strength is -50 dBm on laptop and -55 dBm on aspire one (they are really close, they are on same desktop). Also I did try to bring both laptops to router, and this really didn't help much. Only one of laptops was on when I did speed tests between a laptop and router. I did those tests several times, and interleaved them in different order. For data transfers, contents of /dev/zero were send to /dev/null via TCP connection, using netcat. So here are the speeds: router->iwl3945 = 2.3 Mbytes/s, solid speed, never dropped much, was consistent across tests. iwl3945->router = 1.0 Mbytes/s max, on first test, it dropped often to 300 Kbytes/s Then in another test for whole session it stayed at 200 Kbytes/s, it was same upload speed to ath5k too, the speed varied a lot too. router->ath5k = 1.4 Mbytes/s max, was pretty solid, also noticed that iwconfig shows maximum 18M, although my router supports all B/G speeds. attempts to set higher speed resulted in full connection loss. also association was dropping often, and that resulted in few minutes of no transfer at all. ath5k->router = 1.4 Mbytes/s max, also the same 18 Mbytes/s issue , and same association issue. And now for the worst part: ath5k->iwl3945 = 800 Kbytes/s, but speed very often dropped to 600 Kbytes/s, and once it did drop to around 80~100 Kbytes/s I did see same association drops, but they were rare. iwl3945->ath5k = 500 Kbytes/s and often drops to 300 Mbytes/s.
