Both latest stock and Merlin have crappy wifi issues. 386.5-2 has been my landing spot for months. It will continue until Asus get their butt into gear and fix the bugs in 388.
No WIFI bugs here. Working as it should work! A few minor GUI bugs. SpeedTest error turned out to be a fault on my ISP end. Speedtest to other sites works as it should.
My test:
First WIFI log early morning before 160 MHz clients connect:

Should note that between the first log and the next we had a three hour power failure. My UPS on the router was not going to make an extended outage so I shut the router down after an hour.
Next 160 clients connect but RADAR detected:

My AX86U has been working like this since the 386 code and into the 388 beta and the two releases. We still feel problems others are having are a result of changing the default WIFI settings or your environment. Maybe you have too many IoT devices with crappy firmware?
