Finally got all the bits an pieces and did some experimenting with it. If the weather cooperates, maybe I can get the dish permanently mounted this week.
The mesh router looks just like the main router, right down to the connector ports. Got me thinking... I got an ethernet adapter so I could hook my non-WiFi video security system to the internet. But my new tv also has a hard ethernet connector and it will be on a different floor, so for kicks and giggles I plugged the enet adapter into the mesh router, even tho there is nothing that says you can or can't. Works just fine. Just fine....
So I could get another enet adapter and have each router on each floor with a hard enet connection. Why not just use WiFi you ask? The more devices you have running WiFi, the more contention you have for bandwidth. The devices, your phone, tv, anything with WiFi work in either the 2.4 or 5 Ghz bands. I want to start streaming my TV shows, so I want it to stream unaffected by any other wireless devices in the house, so a hardwire connection eliminates contention.
