Welcome to Why Is A Router Needed On Your Home Network? I’ll explain what a router does and if you need one or not. HINT: Having a router is highly recommended for every home network!
Why Is A Router Needed On Your Home Network?
- Routers allow multiple devices to share an internet connection. Without a router, only 1 device can access the internet.
- Routers assign private addresses to the devices on your home network. This separates your private home network from the public internet and provides a layer of security.
- Some routers provide Virtual Private Network (VPN) security. This allows you to securely connect to business networks, or access devices on your home network while you’re away from home.
- Some routers provide a firewall for additional security against attackers from the internet.
- WiFi routers provide a built-in access point for your home network so your wireless devices can also access the internet.
- Routers provide parental controls to turn internet access on and off as well as block certain websites.
If you have a cable connection at home with a modem, you may connect a computer directly to the modem and use it to access the internet. However, this computer would be vulnerable to attackers on the internet. You also will not have a home WiFi network and no other devices would be able to access the internet. Having a router is not required, but as you can see above a router provides many useful benefits and is highly recommended that you have one.
What is a wireless router?
A wireless router is actually a combination of a router, switch and access point. All of these functions are normally separated in the professional world.
