WiFi 7 mode problem

If I turn off WiFi 7 mode on my Asus RT-BE88U , my new Uno R4 WiFi can connect. It will NOT connect with the wifi 7 mode enabled.
wifi.begin(). returns status of 4. what does wifi 7 mode due?

I am fairly sure the UNO R4 is not capable of WiFi 7 operation.

Most of the "things" in my house connect to the asus router in wifi 7 mode. None the arduino boards connect. Is it a library problem? My new Uno R4 Wifi does NOT connect

WiFi 7 is very new, I have 6/6e and all my things connect to that. I guess the routers are backward compatible so I don't know why the UNO R4 doesn't connect. What is the meaning of status 4? Once you know that may help you.
