I upgraded an ePMP 1000 Sector to ePMP 2000 Sector with beamforming antenna.
Everything seems ok but I noticed than upgrading SMs from 188.8.131.52 to >= 3.0 cause a lower downlink wireless link test result.
Here's the result with 184.108.40.206:
Here's the result using 3.0.1-RC9 (I also tried with 3.0, same result):
I then tried to downgrade to 220.127.116.11 and the downlink speed went up to 70Mbps, in the same moment.
It seems that using 3.0 cause a lower modulation, even if the signal and the wireless conditions are exactly the same.
Look at performances screen:
The Force 180 is very close to the AP:
I didn't change anything but the software version on the SM.
On the AP I have 3.0.1-RC9.
Did anyone notice the same behavior?
I tried a few times and I cannot reproduce your issue on my setup, I have the same downlink and uplink on 18.104.22.168 and 3.0.1-RC9.
I can suggest you try to start Wireless Link Test a few times (for example 3 in series) than change firmware and make same tests on it.
If you want, you can upload or send on my mail (firstname.lastname@example.org) your configuration files from AP and SM, and I will try reproduced it again on my setup (maybe root cause in some specific configuration on your devices).
I tried to start Wireless Link Test more than 10 times always with the same result. Changing the firmware results in a throughput decrease if I upgrade from 22.214.171.124 to 3.0, and throughput increase If I downgrade from 3.0 to 126.96.36.199.
I'm sending you an email about that.
Thank you for operational efficiency, I will let you know about any results.
I feel that I am having a similar issue.
My upload stinks.
I have poor MSC and support says because of interference.
I thought these radios are supposed to handle a noisey environment?
My tests showed are -85 to -90.
Based on your screen shots, it seems pretty clear that v 2.6 is selecting MCS-15 and v3 is preferring MCS-12 for some reason. It would seem like the algorithm is maybe now erring on the side of caution?
