Sorry my mistake "-ac" ofcource .... fixed. "-an" works out of the box ... it has separate interface for 2.4 but i dont want to buy 5 devices and then test backward conpatability on 5Hz interface.802.11an = wifi4 ?
Can't test right now but normally it should be backwards compatible.
Anyhow, 5ghz-an is in the list of possible bands to be used.
ThanksAc works without any problems.
