I live in a 3,000 sq ft two story new build house and pay for 1 gig speed internet. But as you can see in the pic, the speeds I’m getting are underwhelming although they do increase depending where I am in the house. The modem and main mesh router is wired and are upstairs in our master closet. I have 2 more wired downstairs in the kitchen and office and then one wireless in my man cave (where this pic was taken) which is also downstairs (theres only 3 Ethernet ports in the entire house). Would adding one or two additional routers to bridge the distance between the upstairs router and the next closest one in the kitchen help to increase the speeds downstairs?
