Just one router and all good unless you try 5 GHz. Some folk demand full speed at distance on 5 Ghz. Sorry but they won't be happy. That's why I have both bands enabled and to me this is "full coverage."
I have an 1124 square foot single story home, and cannot get full WiFi coverage for it. I have an AirPort Extreme base station in my living room, and when that didn’t seem to have enough coverage, I added an airport express for an expanded network and put that in the middle of my house, and I still didn’t have full coverage.
Today, I went and purchased the new google WiFi home, and it seems like the WiFi has gotten worse. Prior to going out and buying a second google WiFi for expanded coverage, does anyone have any other recommendations? I’d rather it just be one router in my living for full coverage if possible. I have spectrum 100 mbps.
