Yeah, I just ordered a new router since apparently my old one is actually for a much smaller abode. Constant stops and drop out and notices that there is a poor internet signal, blah, blah, blah. The new one is enroute and supposedly gives 2,500 sq/ft coverage. We shall see.
I have heard of people mounting the router in the ATTIC or CEILING crawl space if no attic, and got excellent coverage...............
I bought a wi-fi mesh unit with 4 nodes. I also bought a network bridge. Here's now it's set up:
1. From the cable modem box I connect an Ethernet cable to the parent node of the wi-fi mesh unit.
2. From the parent node I connect to the network bridge box.
3. From the bridge box I run 3 Ethernet cables throughout the house and connect a wi-fi node to each one. Combined with the parent node, I have to nodes upstairs and two nodes downstairs, fairly evenly spread out on each floor.
This allows us to connect with a device from anywhere in the house to one wi-fi name without caring which node our phone/laptop is connected to. Because the nodes are connected together with Ethernet cables, there's no interference from items in the walls or between floors to interfere with the radio signal. Wherever I'm at in the house, there's a wi-fi node near me without much in between us to interfere with the signal. Also, if multiple devices are connected to the wi-fi, you may wind up connected to a node 2nd nearest to you if someone else (or another device) is hogging up the bandwidth to the node nearest you.
