Could someone please give me some insight on this issue. Who has the better performing atheros driver? ubiquiti or mikrotik? I am at odds between the crossroads board or the ubiquiti nanostation for clients. Any input would be great! Thank you all in advance. Rob

Try not using the amps. May be causing more harm than good. At that distance you should not not 1watt amps on both sides.nless there is a specific reason that you are doing so. Under normal conditions cm9 should be fine for that link. imo.
