I have my Wifi network as a 2.4 ghz connection for use with my 2.4 ghz devices and printers. My 'Guest' network is set for 5 ghz to access multimedia devices. From results of a 'repair ticket' -the Guest network cannot communicate with devices on the 'Wifi' network. I suggest ability to add additional 'subnet' to Wifi connection to allow for 5 ghz connections to communicate with devices that only use a 2.4 ghz connection - mainly 'printers'. This was not a problem on my previous Netgear Nighthawk - or an T-mobile internet router I set up. For now I got around it by making an 'ethernet' connection to my main computer- as well as simultaneous 5 ghz wifi connection- which 'passes through' to connect to the printer.
