WHAT DO I NEED TO CONNECT TO THE INTERNET

Don't let companies up sell you on equipment.  Get just what you need.

Internet Service Provider (ISP)- A company that will connect you to the internet.  Spectrum, Verizon, etc
Modem - A device that communicates with the internet
Router - A device that connects multiple devices to the modem

Note:  Some modems also contain a built in router

MODEMS IN DEPTH

A device that sits between your home network and your internet provider. You can’t access the internet without one because your devices and your provider’s network use different types of signals to send and receive data.

ROUTERS IN DEPTH

Wired Router - Allows a direct connection to the router which reduces interruptions or loss of signal
Wireless router - Allows multiple devices to connect to the router
Mesh Router - Allows you to place a few routers in your home in order to extend the signal.  Used in homes with metal or interference, and or larger homes or offices.

Note:  Most routers are a combination of wired and wireless.  You can use either method to connect

ADVANCED CONCEPT  Most current home routers contain a switchboard that allow multiple devices to connect.

 CONCLUSION

A modem offers a single connection to the internet.  Think of it as the main pipe of water to your house.  The Router allows several  connections to the modem.  These are the other pipes that branch off.
