I.e. PWR MGT is 0 at home, too. Beacons (and all other frames originating from the AP) will always have the PWR MGT bit zeroed, because AP will never sleep. > We have multiple APs at work; I assume that in normal operation the > tablet is registered with only one and will ignore beacons from > the others.

There's a setting in Wireshark under IEEE 802.11 to enable and disable FCS calculation. Try reverting that option. -- Kalle Valo _______________________________________________ maemo-users mailing list maemo-users@xxxxxxxxx https://lists.maemo.org/mailman/listinfo/maemo-users
