RT-BE88U

I love my ASUS RT-BE88U WIFI 7 router paired with several ASUS RP-BE58 Mesh extenders. Just “marry” the extenders to the main router and in your case,use the RT-AC86U as one of the extenders. Good luck! WIFI 7 is almost 2X the speed of WIFI 6.

Go for a WIFI 7 Mesh system. I Love ASUS, excellent software,frequent firmware updates. Good Luck!

Asus ftw. I’ve got 4 in my apartment. 3 are wired and one is on the 5Ghz mesh wireless and I still get 500Mbs from that one from the opposite side of the room from it. I have two x BE88Us, my router is set to pass through mode so one of my BE88Us does the PPPPOE for my internet connection too. Also don’t use stock ASUS firmware, flash Merlin. It’s super easy. They only support the latest ASUS routers though.

Have been running Asus and AIMesh for over 10 years.  Consistently excellent.   Currently have a RT-BE88U (Wifi 7) and a RT-AC86U ( wifi 5) in mesh and zero issues.  All the iot devices are on their own network.  Homeassistant server runs on main.   About 50 devices total 

Got rid of my shitty nest wifi pro and bought a wifi 7 Asus aimesh network setup. Light years ahead and can reliably stream my PC at over 100mbps over wifi. So can do the portal with ease whereas the nest could not

When my Nest wifi was finally on its last life, I purchased a much more expensive Asus mesh router setup that supported wifi 7. For whatever reason the more advanced features of MLO didn't work with my TV. So basically I had to cripple my expensive setup to work with the device I use all the time. I ended up returning that and switched to the Nest Pro and have had no issues. Been about a year now. Solid connectivity and speed. I bought the 2 pack for 250, not on sale.
