Best thing I have found for wireless and wired connections. Google Mesh Routers/extenders/range. I have 2 set up in my house, and a line running to a switch in my bedroom. All connections are incredible, and I receive about 200 mbps, which is great considering I pay for 75. In a metropolitan area even.
I also love that I can view my traffic and remotely prioritize things, share ownership with people via text which means no SSID/key required when on the fly, and I am now running three systems in different sections of my city(my home, my brothers home, and my mothers doctors office). The owner of my company got me on them, and if he shares the office with me, I can run a 4th(I'm unofficially/officially the IT guy for our very small business). This is after going through close to $1000 in different modems and routers trying to correct some issues with Wifi vs lead painted walls, and connectivity with my switch. Would recommend checking it out sometime, downside being the cost($99/unit, most homes should have atleast 2, comfortably 3).
