I was configuring for a PTP connection using 2 SXT 5 ac in a small room, close to each other, to test the configuration before going to field.
Well, the device was working properly in the beginning, but, once I started to make changes in order to achieve a higher throughput, the device started to get slower, slower (lower throughput) and finally it is not transmitting anything through the wlan1 connection. The log shows that it connects, but I’m seeing now a very low CCQ (6% or less) and nothing is being transmitted. Here is the statistics I collected from the client device:

The other guy showed me one screen capture from the device in its first test performing a very high throughput, but since then it’s only getting worse. The more we configure, less they work. It’s very frustrating.
You probably think that the more signal strength the better throughput. That’s false obviously as you have proved. Just attenuate the signal by 25db on both sides and it will be working fine again…
No, I don’t think. I’m reading a lot about this since I was informed about the conditions of this lab, even before I started to work with the devices directly. I definitively agree with you.
I’m trying to reach the magic number of -50/-60 for signal strength, but it seems to be impossible. I tried reducing the tx-power with all-rated-fixed mode without success, as well as increasing the antenna gain. This device does not support some tx-power options, so I’m trying to combine other values to see how it affects those numbers, but the combination of all parameters creates a lot of possibilities, and its precisely what I’m trying to understand here and, obviously, leave this discussion as a research material to everybody who comes after us.
Is it useful to keep reducing the tx power, even using negative numbers, to attenuate the signal? Is it really possible to be done only by configuring the software?
Well. Using the regulatory domain and rising antenna gain value leads to lowering the tx power usually. Also moving them a bit far away or turning to the side will lower the signal level. Play a bit with it…
