3dB differrent between 2.6.2 and 3.1

Dear, I said that we have detected a difference of 3dB less with RSSI and 6dB less with SNR between the verison 2.6.2 and 3.2.1. The SM (Force 180) is at a distance of 10Km
I have read that something similar happened with 3.0, and in 3.1 and should be solved the problem, but in my case seems to continue to happen.

The AP has 3.1 installed.

Some news??

I tried with version 3.2.2 and the problem persists.


I can't find the thread, but I believe that there were some SnR/signal reporting issues between older and newer versions of the ePMP firmware. There's not an actual signal change, it was just how data is reported.

Apparently version 3.2.2 does not solve the problem.

It’s not a problem, but an old display bug fix. Previous versions of the software combined the pols and sometimes yielded 6 point Mimo gain rather than three. There is no impact on performance and you should be able to find that notation in 3.0 or 3.1 release notes.
