I just bought an RT-AX92U two pack and set it up as a mesh network, but it is very slow on the 2.4 GHz and 5 GHz bands. I upgraded the firmware on both and I followed recommendations on forums for settings that could fix the problem, but nothing worked. I tried using just one of the routers by itself and split the bands so I could test each one individually. After multiple tests, the best I could get was 50.8 Mbps on the 2.4 GHz band, 13.5 Mbps on the 5 Ghz-1 band, and 339 Mbps on the 5 Ghz-2 (WiFi 6) band. What could be causing the 2.4 and 5 GHz bands to be so slow? I attached images of the current settings. I got the same speeds when it was on the default settings. I'm on the 188.8.131.52.386_46061-g9a06866 firmware version, but I got the same speeds on the firmware that came with the routers.
