Tp link px50 is a decent consumer system.
Deco x50 mesh system with maybe 2 units ? Allways can add more if you want and need.
I have just under 2000 sqft in a two story house (3 if you count the basement). I have my main deco router upstairs on one end of the house and the second on the main level on the opposite end. No matter where I am I get full strength signal. In the past my main level deco went offline and I noticed connectivity issues especially in the basement. With various iot devices like cameras and the thermostat stability matters more for me. Now that I’ve had a mesh network I don’t think I can ever go back.
I run Decos (AX3000) in my house which was built like a f\*\*\*ing faraday cage. 2300 feet and I need 3 mesh units to get coverage throughout, plus another one just outside the back door (X50) to reach the backyard, otherwise the signal is gone after 15 feet.
I’d actually argue that a simple mesh, like a Deco AX3000 (around $320ish) would make more sense even for small homes as you are going for coverage. Put one at one end of the house and one in the other. In my opinion it’s those “gaming routers” that are generally overkill (especially the ones with a million antennas and LED lighting.
You already have a lot of good advice. Restech is a Wisconsin-based internet service provider that also offers tv/streaming services. https://www.restechservices.net/for-property-owners/ They’ll probably offer various speed tiers. Don’t let them oversell you beyond your needs. You’ll probably not need a modem but definitely could use a router for basic protection and WiFi. For a budget-minded person, a recent model TP-Link AX3000 router is often available on FB Marketplace for around $40. As you configure your router, change the default DNS to 1.1.1.1 so your service provider is not tracking your surfing destinations. You can also subscribe to the free level of Proton VPN for added privacy. You may be able to get some volunteer assistance for setting up your router. Check with your local library for resources.
