Hi, I've taken a quick peek. There's nothing obviously wrong with that trace. Can you please redo this with: * 5 runs? * 100 pings a second - ie, ping -i 0.01 * capture the output of athstats -i ath0 before and after each run, as well as during a run * let it run for say, 60 seconds at a time. Also, once that's done, try it again with this: wlandebug -i wlan0 +power +input +output +state +assoc +mlme see if anything interesting pops up at the same time as your latency increases. (then wlandebug -i wlan0 0 to disable it all.) Thanks, Adrian
