I’m being faced to a strange lack of bandwith on an nstreme 13km link.
Both boards are RB333 with latest Routeros running on. Signal strength is about -62db and data rates stays at 54Mb Usualy i can get easely up to 30Mb with the bandwidth-test tool on this kind of link. Here, no way to take away from 8Mb before my far end equipment becomes unreachable ! Doing tests in both directions is even worse… I tried many other frequencies, the result is the same. So i turned off nstreme and then can get up to 22Mb in one way but still very bad when using both directions.
What could be the problem with nsterme? No lack of cpu, bandwdith-tests are made with (from to) two RB600 directly connected to the RB333 bridges.
Well, traffic between single radio´s is always simplex. ie. the data flow is only in one direction at the same time. If you want to put dataflow in both directions, the radio´s have to switch between ´sending´ and ´transmitting´ all the time and you get only half the speed for each direction compared to the speed for ´one way traffic´ only.
The reason for the bad n-stream failure I don´t know, my knowledge is not deep enough for that. I do know n-stream actually performs better then non-n-stream in heavy data transport links, which you do create with a bandwidth test. So the problem must be found somewhere else…
there must be other readers on this forum that might have better ideas?
I ran Nstreme with CSMA disabled on a 900MHz WDS link and it was much slower. I could watch an avi over the link after unchecking the CSMA box, but couldn’t watch it with.
I haven’t disabled Nstreme yet to test as the link is now in use. I’ll try it again and see what the throughput is.
