At least N800 and N810 do, we don't want to miss any of broadcast and multicast traffic. But I don't know how other mobile devices wakeup for beacons. > So another idea would be to burst beacons but make sure the DTIM > beacon time doesn't fluctuate away from the DTIM TBTT.

At least from my point of view that could possible. Of course it feels like a bit of a hack, but I guess there's no clean way to implement this. -- Kalle Valo - To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
