Short answer

If whole rooms are weak, a mesh Wi-Fi system is usually the answer: two or three units spread around the home make one strong network. If only one device near the router has trouble, a network cable is the cheapest fix.

How to connect it

  1. Plug the first mesh unit into your internet box with an Ethernet cable.
  2. Place the other units between the router and the weak rooms; they only need a power outlet.
  3. If your provider's box is also a router, ask about bridge mode so you do not end up with two networks.

Check this first

  • If only one device has trouble and it sits near the router, a cable is the cheapest fix. If whole rooms are weak, a mesh system is usually the answer.
  • The first unit plugs into your internet box with an Ethernet cable; the others only need a power outlet.
  • Many mesh units also have Ethernet ports, so a TV or console near one can plug in with a short cable.
  • Wi-Fi 6 or newer suits most homes today. Pick a pack size to match your home: two units for most apartments and smaller homes, three for larger ones.
  • If your provider's box is also a router, ask the provider about bridge mode so you do not end up with two separate networks.
