Well.. the hardware does support all 2GHz and all 5GHz channels indeed, but that doesn't mean it allows you to use em :) Different countries/regions apply different restrictions on the allowed channels, eg. US does allow 1-11, Europe 1-13, and JP 1-14. Now Intel as a hardware vendor applies those restrictions by using different EEPROMs. So, even if the hardware supports every possible channel, the EEPROM content can prevent you from using em. > BS> get all supported channels for a certain interface with: > BS> ifconfig -v wlan0 list chan > BS> Compare that list on AP and client side. > =C2=A0I =C2=A0need =C2=A0to boot FreeBSD on client for that :) I'll do th= is, but not > =C2=A0right now :) Ok, you might also be able to use some scanning software to check if you see frames sent from the AP. > BS> Just wondering, did you set a countrycode/regdomain via ifconfig > BS> country or ifconfig regdomain?
