I'm afraid, that will be difficult. I could try 8.2-RELEASE and even 8.0-RELEASE (but I'll need to build NanoBSD images for them). I'm sure, that 7-STABLE gives me 3.2MiB/s regularly, but noteboks were changed from these times. I'll try to build 7-STABLE NanoBSD image, but it will need some more effort, as config files changes from these times :) > 2) not sure, it's late and I'm not knee-deep in the beacon frame > format. But I bet it's ok? It is "not accurate enough" :) Many APs, seen in my apartments, announce all speeds up to 54Mb :) But, of course, It is practically Ok ti= ll clients can connect on higher speeds. > 3) txpower is in dBm units, based on what the card is supposed to be > putting out of the antenna socket, before antennas Ok, so 30 means 1:1 (according to dBm definition) and means "full power". --=20 // Black Lion AKA Lev Serebryakov
