From my own investigations into the LMAC sources, that event is triggered by an internal LMAC timer if it hasn't received a beacon at all in that time. Disabling powersave operation makes the problem go away entirely, so I suspect what's happening is that the LMAC is consistently waking up a little too late (or going back to sleep too early) to hear the beacons. My guess is that the LMAC is pushing its powersaving margins too close. > Btw. how old is the fw bin you have? I'm using WSM395 currently, dated June 18 2012. (It fixed a problem that a client of ours observed with WSM392 and WSM385; the LMAC would lock up on noisy environments when block acks were in use) - Solomon -- Solomon Peachy pizza at shaftnet dot org Melbourne, FL ^^ (mail/jabber/gtalk) ^^ Quidquid latine dictum sit, altum viditur.
