I am testing two setups:
1) RB922UAGS-5HPacD.
2) RMB33G with a R11e-5HacD radio module.
I have set them up on 80MHz wide channels with 5GHz-only-AC band setting. When I run the Mikrotik bandwidth test using UDP packets the best throughput I see is around 100 to 145Mbps Transmit and the same receive. At best this is around 290Mbps total throughput. AND this is NO WHERE NEAR the 867Mbps throughput these radios are supposed to be capable of.
Test is not over air - it is through coaxial cables and attenuaters (70dB of attenuation). Signal Strength around -50dB - I have tried using different protocols and settings but nothing seems to improve the wireless data rate.
When I had tested the RBM33G with the R11e-5HacD card a few years back the 802.11 wireless protocol setting was giving me around 420 to 480Mbps throughput over the same attenuator setup I am using now.
Couple that with the fact that the new RB922UAGS-5HPacD has an additional problem in that - no matter what I set the Tx Power to (6dB up to 30dB) the signal strength basically does not change. It is like the Tx Power is stuck at a moderate setting and acts like it is no where near the 30dB max output power advertised for this board.
This is really substandard performance and I am evaluating these radios for inclusion in our small companies product line - this this would equate to the sale of over 500 of these in the next year or so.
If I cannot get an answer or any support we will have no choice but to drop these products as the performance is no where near what manufacturer claims.
Question: Is anyone else seeing this? Is this standard for this product?
If you need a settings file I will be happy to provide it.
Hopefully someone will respond????
