When I disable 6mbps it announces as: 11:39:06.596019 802.11 flags=0<>: beacon, caps=10421<ESS,PRIVACY,SPECTRUM_MGMT,RADIO_MEASUREMENT>, ssid (catap's Network), rates 9M 12M* 18M 24M* 36M 48M 54M, ds (chan 40), tim 0x01040000, country 'DE ', channels 40-41 limit 23dB, power constraint 0dB, tpcreport 0x0000, 195:3 0x011e1e, 70:5 0xf200010000, 51:3 0x082830, 54:3 0x961000, rsn=<version 1,groupcipher ccmp,cipher ccmp,akms PSK 4 SAE,rsncap 0x80>, 3 stations, 3% utilization, admission capacity 976us/s, <radiotap v0, 0Mbit/s, chan 40, 11n, sig 48dBm, noise -106dBm> so, AP works as expected. Thus, the issue that this setting was made year ago, probably two and everything works well in this network with one exception: my laptop which I've upgrated from 7.4-stable to 7.4-current.

Thanks for bring it, I've moved back to auto mode with hope that it works cleaner. -- wbr, Kirill
