I'm pinging the access point from an associated wifi client: when this message appears one or two pings are lost. Previously, when such messages didn't appear, no pings were lost. Maybe the reply timeouts and is not completely lost, I'll do more tests asap. > "every few seconds" is not helpful. Actually the timing is highly variable, it may happen once a second, like once every 15 seconds or more. Usually (in the two hours I tried) every 2-5 seconds. > Look for something else in the > system that coincides w/ your msgs.

I'll try, I haven't done additional tests before knowing what would be useful for debugging. -- Alex Dupre
