802.11 n Deployment

Im just about to deploy a new network. Testing on < 4.3 with N cards has been flaky. Is 4.3 now stable.? If I downgrade ROS to 3.28 will the “N” cards still function in the 802.11 a range

thanks

downgrading to v3 will make the N cards disappear from the interface list.

As the testing has been flaky and 4.3 does not appear to perform as stated, should I return my N Cards to the Distributor for replacement with cards which should work correctly ?

Thanks for your very quick response

you should contact a consultant, or email mikrotik support to improve your connections.
