A:Answer My understanding is that your router should be choosing the signal, either 2.4 or 5, due to the workload the router is experiencing at the time of the printer use. I have a tri band router so I am able to designate certain items in my home to run on the 5 as opposed to the 2.4, to ensure the best connection. An example is my Sony 75" 4k HDR tv,that I designated to the second 5ghz band of my router to ensure the best playback from Netflix,Vudu and other apps.
