I think that the zydas mac doesn't officially support 5/10mhz operation. I don't know how it's supposed to. As for the alternate frequencies - it all depends what it's calibrated for. The PHY and radio support whatever the AR5416/AR9160 do (as they're the same PHY/radio), but it does depend if the board design and calibration has been done with those frequencies in mind. So by default, please, leave them off. :-) adrian On 5 June 2013 05:59, C.B.
