I recently moved into a newly constructed house. The builder contracted an AV company that ran Cat 6 Ethernet to each of the rooms. The house has a basement, first floor and second floor. All of the Ethernet cables terminate in a basement low voltage panel where the cable company coaxial cable also enters the house. I connected the modem to a router and then to an eight port switch where I connected all five rooms in the house. Unfortunately having the wi-fi router in the basement reduces the radio signal to my wireless devices (iPad, etc.). Looking for equipment placement/hardware upgrades to maximize wi-fi in the house. I assume having the router in the basement between the modem and switch provides an important firewall.
Very nice on getting the wiring ran to each room, what you need to do is disable the Wi-Fi on your primary router and install a wireless mesh system such as Eero or Tp-Link deco, both of which can replace your router entirely. You would place one unit in the basement and then place the other two accordingly hardwired in one or two of the upstairs rooms.
Do you mean I should remove my existing Linksys router in the basement and then add two mesh nodes, one in the basement and one in an upstairs room?
Would an alternative be to leave the Linksys in place, disable the Wi-Fi on the Linksys and add say a single node mesh like eero on the first floor and hard wired to one of the cat 6 lines in the upstairs room?
