Comment 52 for bug 341952

I noticed that, immediately after booting the computer, ath_pci (madwifi) works correctly, but then it starts degrading in performance (both latency and bandwidth) and in a few minutes it's back to a horrible state like this:

--- 192.168.1.1 ping statistics ---
18 packets transmitted, 18 received, 0% packet loss, time 17026ms
rtt min/avg/max/mdev = 2.530/5.401/12.738/2.476 ms

(notice: this is the gateway and it's always been stable < 1ms in ubuntu hardy usually). Speed tests go from an optimum 6/1 Mbit (which is my nominal speed) to 1/0.128.

$ lsmod | grep ath
ath_rate_sample 21888 1
ath_pci 224832 0
wlan 259232 5 wlan_tkip,wlan_scan_sta,ath_rate_sample,ath_pci
ath_hal 339088 3 ath_rate_sample,ath_pci
multipath 16512 0

I'm using this snapshot: madwifi-hal-0.10.5.6-r4016-20090429.

Can somebody please certify which exact driver was being used by Ubuntu Hardy? Was it MadWifi? If so, which exact version/snapshot? I would like to test with that exact driver. Otherwise, I'll have to assume that running "ath5" once on my card misconfigured it in a way that madwifi is not able to recover anymore.
