Hi and thanks for the reply. I had reduced the beacon frequency before and after upgrading to 2.6.24 and although it makes a bit of a difference it doesn't account for the time my processor is in C2-now I'm back to the default 100 ms for it seems that a Vista laptop has problems connecting to the router in these conditions. So to recap, 2.6.24 compiled from source as well as from Debian repos (hpet=force) do show a behavior not seen before with 2.6.22 with the mentioned patches. I'll try to chase down this a bit further if I can. _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
