Therefore, for D-Bus interface, the idea would be to add an entry in the Capabilities array of each interface which would look like this: dict entry( string "Capabilities" variant array [ .... dict entry( string "IEEE80211" variant array [ string "g" string "a" string "b" string "n" string "ac" ... ] ) > sudo dbus-send --system --print-reply --dest=fi.w1.wpa_supplicant1 > /fi/w1/wpa_supplicant1/Interfaces/7 > org.freedesktop.DBus.Properties.GetAll > string:"fi.w1.wpa_supplicant1.Interface" > > is where that kind of thing should show up if implemented.

Here it would be a little bit simple, I would just add N and AC with their own supported channels to the list. Something like this: Mode[B] Channels: 1 2 3 4 5 6 7 8 9 10 11 Mode[G] Channels: 1 2 3 4 5 6 7 8 9 10 11 Mode[N] Channels: 1 2 3 4 5 6 7 8 9 10 11 Mode[A] Channels: 36 40 44 48 52 56 ... Mode[N] Channels: 36 40 44 48 52 56 ... Mode[AC] Channels: 36 40 44 48 52 56 ... What do you think? I would like to propose a patch with this.
