Looking for a router with Controls to easily turn On and Off the Wifi channels separately

[Markd57]

 Need to be able to isolate 2.4 Gig from  5 Gig signalling.   

 Is there a NetGear Model that the user can easily Turn Off 2.4 G and Only Transmit 5G and then  Be able to Turn Off the 5G and turn On the 2.4 G.

What is the real-world business case or problem you intend to resolve?

The brand new WAX204 can be operated as an access point or as a router, offering current WiFi 6 and WPA3 personal of required.

As per the WiFi 6 AX1800 Dual Band Wireless Access Point WAX204 User Manual :

p.60 "Set up or change an open or secure WiFi network", you can select the band where each wireless name (SSID) is active. "Select a radio button for a single band (2.4 GHz or 5 GHz) or keep the default selection, which is the Both radio button, to enable the WiFi network to broadcast on both radio bands."

p.70 "Enable or disable a WiFi radio" Each radio can be enabled or disabled individually, except if the very powerful Smart Connect feature is enabled: ADVANCED > Advanced Setup > Wireless Settings.
