I have a wAP ac and Macbook Pro 3-4 meters and one reinforced wall apart from each other them both are sitting still. During video calls, I frequently (few times in an hour) experience "disconnected, received disassoc: sending station leaving (8)" followed by "connected, signal strength X" where X is typically in range between -45 and -55. During the last call, I had wifi measurements on on my MBP and the rate was above 450 Mbps, noise was steady at -97 dBm, and "quality" between 50 and 55 (I don't know what quality represents but could be S/I).
Based on https://wiki.mikrotik.com/wiki/Manual:Wireless_FAQ, I checked frame vs hw-frame difference and noticed a large gap on Tx but I don't have an idea how to fix it:
Tx/Rx Frames 138 936/136 102
Tx/Rx Hw. Frames 328 012/145 000
Disconnection message help suggests: Possible causes - too weak signal, remote device turned off, strong interference, some other RF related issue that makes communication impossible.
Does anyone have suggestion how to proceed with troubleshooting and getting rid of this problem?
