I need to upgrade my home wifi network with a high speed mesh network
(primarily for better phone coverage in my house - I make a lot of video
calls to the UK). I have Cox Gigablast on my wired network. The issue I am
running into is that the "base" unit of the eero units and other vendors'
boxes have to connect to either (1) the cable model or (2) the router and
not the switch. My modem, router, and switch are all in a cabinet above my
desk in the office, so (1) I don't need wifi in the office and (2) I don't
relish the thought of having a wifi transmitter sitting 3 feet from my head
12 hours a day. I want to connect the wifi boxes to my wired network in a
couple of different rooms away from the office. Eero (and other vendors)
says the "base" unit has to act as a gateway (my router does that now), so
it cannot be after the switch. Any suggestions on how I can get a high
speed mesh network in my house and not take a daily showert in 2+ GHz
radiation? I also want to use the wired network as the backhaul channel.

Please don't start a discussion on the health effects of wifi radiation.
Just assume I am so unscientific and superstitious that I believe in wifi
gremlins and I don't want them invading my head.;)

Thanks!
