Why do I need a cable at home despite WiFi?

hope this helps (*＾▽＾)／

Explanation:

First, your internet service provider sends a data signal through the coaxial cable, or coax cable, into your home—specifically, to your modem.

The modem then uses an Ethernet cable to connect to your computer or router, which is what gives you access to high-speed internet. If you choose to use a router, you can then broadcast a Wi-Fi signal throughout your home.

Cable internet service providers transmit data between servers using this coaxial cable, and since TV itself takes up only a small portion of the cable’s bandwidth, it leaves room for internet service to work within the same network.

These cable networks stretch all across the country, and there are even undersea cables that reach between water-separated areas. Plus, cable internet can spread speeds evenly among individual users. It also means that if you pay more, you have access to more bandwidth, which means faster speeds.
