hi
i got a link MT411u (AP bridge) to 411 (station). both got R52Hn cards on connected to dual-pol dishes. OS on both is 5.13
the link is 34km. signal for both chains flactuate between 66/67 and 66/74 (max), signal to noise 40.
I now use 20Mhz and N only which gives TX/RX rate of 52/54 mbps. With bandwidth rest i get tx 11 mbps and rx 10 mbps.
Data rates is default and HT AMPDU priorities I have only ticked 0.
I am used to have on this link about +20 mbps rx and tx true throughput but am not getting it anymore and cant usnerstand why. i have played with the frequencies and this is the best I get. Before playing with the frequancies, I had ping times of 200ms+ and the ack distance was reported as 54 km. Now that I have made changes to my frequensies my ping times are ok (2ms and less) and ack distance is 47km ALTHOU real distance is 34km. CCQ is ok (flactuate beteen 61 and 81) but I can live with that.
Everything else is on default settings except Adaptive Noise immunity which is on AP/Client mode. After enabling it, my data rate is slightly more stable.
Can any one help me getting it back to what is was before I kill this link with a sledgehammer? At least I’ll feel better afterwards
