I have a RT-AX88U and and a RT-AC68U using AiMesh with latest AsusMerlin firmware , my laptop has an "Intel(R) Wi-Fi 6E AX211 160MHz" card and I noticed that after a couple of hours connected at 1201/1201 Mbps (router is 6ft from the laptop) the connection speed drops to ridiculously low speeds (I've seen 144/144Mbps), disabling and re-enabling wifi on the laptop resolves the issue.
While trying to debug i noticed that forcing the channel width to 160 Mhz seems to have no effect, my SSID is always shown to use 20Mhz on the router Site Survey Page (no other SSIDs around) no matter what I set on the router Wireless Settings. Any clues will be appreciated this is a problem that has haunted me for some time, even with other laptops using similar Intel AX Cards.
