Update: The latest beta firmware (20250619-rel21989) has finally fixed the issue. An official firmware will be released with the fix. Cheers!

Hello, 

I set the RE655BE (EU) up as AP mode.  

Configured OFDMA on all bands, and MU-MIMO where possible (5 & 6). These settings can only be set on the web interface, not the app for some reason.

I set everything as Wifi7 WPA3 (or WPA2/WPA3), disabled WPS (though the AP is still signaling the WPS tag on the 2.4 and 5 bands for some reason), put bandwidth for every band to their respective maximum (40, 160, 320), and set the lowest channel on all bands.

I haven't tried EasyMesh, as I have no other EasyMesh devices. The router has wifi completely turned off, so the RE655BE is the only networking device emitting wifi in my home's network.

It's rock solid, and the signal is great even though I have a TON of neighbors and office wifi signals around me (it's a high density mixed-use apartment neighborhood). 

Buuut... If I turn on MLO, even though I only have one device using it, stability breaks. It happens more often when my MLO smartphone is far away from the AP. After a while, all wifi goes offline (including non-MLO). OFDMA and MU-MIMO don't change how often it crashes. The AP is still accessible from ethernet, but no wifi available whatsoever.

When wifi was down, I logged into the AP using ethernet, and did a small test: I changed configurations on MLO, and also on different bands (because that triggers a wifi network restart), but it didn't make wifi work again. I have to reboot it to make wifi work again.

So... In summary, if you disable MLO, the RE655BE is a rock solid device.

But MLO is just a no-go for now. 

Hoping that you will fix MLO sooner than later. 

Cheers!
