In the adhoc case I thought the beacon xmit was handled entirely in the radio while for the ap operation it requires the host to post the beacon frame at SWBA? I thought using AP mode was to fix multi-vif support? If beacons are being delayed due to the channel being busy then that's a separate issue--unless the AIFS parameters for AP are different than ADHOC operation. > > 2) 2.4G and 5G are having the same behaviour. > > 3) When i tuned the Fluke to detect my normal AP, the beeps are > > consistently in a very fast interval.
