I have a 31 mile link using RB433AH’s and XR5 Cards. My first try using Dual-Slave Nstreme, everything is setup correctly, signals are -61db TX -64db RX 54Mb*2
Problem, throughput is 14Mb UDP and 1500k TCP. FW is 4.10. I know the signals are great because when I try each card configured as BRIDGE to Station WDS, the Pthroughput is 55,000kbps and actual speedtests are 100%. Is it a FW issue on Dual-Slave issues? It worked great on the bench where I was able to get a solid 50M/50M full duplex, but now the radios are in the field with 31mi air link, they are performing horrible.
I got tire of messing with it so I just used 1 card in 5Ghz Turbo. Also I don’t like the idea with Dual-Slave that each site is “locked” on a specific frequency, if any interference comes around and you need to change channels and can’t get to the other site without a site visit, your screwed. When I need more bandwidth I will simple upgrade to SR71-15 cards 40Mhz single-chain. Also the XR5’s take up way more CPU usage.
