I recently purchased a RB411A and RB600 routerboards, along with two Ubiquiti 3-7 cards to test for use on out licensed wireless network.

I updated to the current OS 4.3 and installed the cards onto the boards. Both boards are reading the UBNT cards as 5 GHz cards instead of the 3.65-3.7 GHz.

Is this a compatibility issue and MikroTik cannot read them correctly or is something else going on here? It was my understanding that the UBNT cards would work in these RouterOS boards.

I am going to send the same message to Ubiquiti and also see what they say.

yes, there is a table conversion of the frequency, ask in the ubiquiti forum, they will give u.
