ASUS RT-BE92U Private and Guest network best settings setup

[ABaSP]

Hello everyone

I have just got the ASUS RT-BE92U router and have not set it up yet and need some advice before do so to do it properly from the beginning. I need some help on how to set it up for best security for private and guest network and would like to isolate those from each other as best can be done. I have some WiFi speakers, Samsung Soundbar Q90R and Sonos Playbar + 2x Sonos One all supports only 2.4Ghz. I would like when guests want to use my WiFi for internet and stream music to the speakers (only) be able to so but not on my Private network which only I would be using. But then I would like a smooth setup where I can have those devices also somehow to be available to my Private network too because I would also would stream music to but my personal device like my Pixel phone should not be visible where guests devices is as I would want to use my Phone for Administrating the router when needed mainly because I dont want when guests are over not see when I Administrating the router on TV screen in living room where all my devices is and where my laptop is connected to both router (wired) and TV. Never ever have I done this similar setup and have no knowledge on such thing and that is why I would appreciate it a lot for help/advice and setup? I also have the ASUS RT-AX82U (V.1) with latest Gnuton FW.

Highly appreciate any help/advice

Based on the number of issues this router has my only recommendation is to send it back. Non-working QoS (like in most BE-class ASUS routers), weird issue between guest network AP isolation and LAN ports (discovered lately), common connectivity issues (clients dropping), lately false advertising about MLO (minimum support only, no real benefits), etc.. You had to do some homework before buying this model.
