RT-BE88U 2.4GHz backward compatibility settings

[aridair]

Can anyone tell me what the most backward compatible 2.4GHz settings are for the Asus RT-BE88U router (Wireless->Professional in the web GUI) for devices that worked with WiFi 6 routers (Asus/Zyxel)? I know that it can work, because I randomly choose the correct settings, but I didn't write them down The device is a homewizard P1 meter. I also have a Plugwise P1 meter that does connect to the router with whatever setting I use.

I've disabled wifi7 on my IoT network for all my legacy devices to connect. I tried WPA2/WPA3 with wifi7 and that didn't work.
I think disabling wifi7 on that one network should be enough.

That was the first thing I tried but that didn't work. Here are the settings I'm using now (I thought to be backward enough) but no success

Just to compare, I've added my professional settings for 2.4GHz. I think all I've done is disable roaming assistant and dialed back the power (power would not affect compatibility).

Thanks, I copied your settings (except the WiFi 7 ones), but no luck

WPA2 only is what got my IoT devices working.
