Hello,
I have a link with four stations and 20 mhz/5Ghz under 11n. It runs great (up to 40 km and up to 40 MB/TCP). When I connect one Rb911ac-Board (11n Mode only as a station bridge, no traffic) to the link, the link of the same stations become unstable and the speed goes down and as well the ccq. The signal off the 911ac is -59/-60 and is 10 km away. This happens to a few conntections under 11n when I connect one RB911ac or a Metall 921ac to an 11n link, which runs great until an “ac Board” is connected to the link. There is no traffic on the ac Board, just the connection is engough to slow down the link.
This happen as well under some 20 Mhz 11a connection. I do not know why. I want to change all my connection to 11ac, which will be arround 70-100 Boards to buy in the first place (up to 200 later for the local backbones).
I already reported this to MT, but I do not get any solution. They only asked me one thing, but no answer or tipp until today..
Does anyone has the same problem with the new ac Boards?
