QRT (RB911G-5HPnD) Very Low Throughput

Wed Jul 08, 2015 4:43 pm

We have installed a pair of QRT units as a PTP backhaul, almost 19km, and have very good line of sight. We are using 5GHz-A 20MHz channel with 100% CCQ values and a -61dbm signal on both ends. We can use the built in bandwidth speed test and get good results, usually around 35 mbps to 43mbps using TCP. In actual use we can only push between 3mbps to 6mbps of real data. We have tried N mode, wider and narrower channels, all with no change. Another problem we have is the units will only associate in NV2 protocol. We can't get them to associate using 802.11 or NStreme. I have probably done something wrong but can't figure it out. I have also upgraded to 6.29.1, updated the firmware and have even tried the Wireless-FP package. Any ideas on what might be the problem? I can provide config's if needed.

What do you mean by real data? Isnt the speedtest you did real data ?
