Today we upgraded a link between a RB411AH and Groove A-5Hn, changing the RB411AH with a RB Metal.
Link is LOS, but a tree is inside the first Fresnel zone.
Old link was wds+nstreme+11n with ROS version 5.22 on both side. Max throughput was about 35 Mbps.
New link was with nstreme+11n, ROS 5.25/5.22. Same frequency and same antenna.
Distance: 50 _meters_, signal-strength at -55dBm
Without WDS and about 15 Mbps, ping were about 200 ms, CCQ fluctuating between 30 % to 90 % and p-throughput from 4 to 95 Mbps.
Now, with WDS enabled and same traffic pings dropped to 27 ms, CCQ rose to 90-100% and p-throughput is stable to 40 Mbps
Dear guys, somebody can explain me _why_ wds, which should just *adds* some bytes to frames, gives a link so more reliable?
