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.

From GT-BE98 Pro, but hope it helps...

Specs for one of the P1s...

@Ripshod You've enabled two WiFi 7 settings and disabled 2 ax settings if I'm not mistaken...

Yeah. Those settings affect all 2.4 networks, including the main wifi7 ssid. Like I said, the only 2 changes I've manually made (on this page) are to disable roaming assistant and reduce the TX power. I haven't even disabled explicit beamforming, which was standard practice on my old RT-AX88U.

disable roaming assistant and reduce the TX power

This by itself may help a lot resulting in reduced noise and number of disconnections around the edges of coverage area. The default Performance setting on Asus routers cranking the Tx power up to allowed limits if often hurting the performance.

And something else:

If we are talking about Professional settings - give us Professional settings in dBm number for the specific device and region, please! What is Performance and what is Balance for RT-BE92U and for RT-BE88U in the UK or US for example? The same output, different output? Different hardware radios, different dBi antennas, different region - I expect all 4 combinations to have different output. Are you listening, Asus? There is nothing Professional in current settings. It's a guessing game for the user.

Thanks a lot for your responses! None of your settings worked and I moved on to do a factory reset. I'm not sure where in the setup process this occurred, but I got a special IoT page asking to create a network for legacy devices! That's what I did and it worked .

The asuswrt-merlin firmware survives the factory reset and isn't the cause of connectivity problems (which I intended to rule out next). In the Wireless->Professional page of the managment GUI there is no reference to this special IoT network and I don't know how it's configured nor can I change any settings. It's all very puzzling.
