Comment 51 for bug 341952

Sorry, did not notice you did have installed ath_pci. But can you compare ath5k vs. ath_pci ping performance. When I get toping google.com

^C
--- google.com ping statistics ---
31 packets transmitted, 31 received, 0% packet loss, time 30044ms
rtt min/avg/max/mdev = 39.709/40.080/40.829/0.357 ms
, I most of the time see 0% loss.

Sometimes though, I get up to 5%. I do not see much difference between them now. I had, when noticing almost 0 upload rate on ath5k. This might have been fixed by now....
