Wi-Fi network security

Your Wi-Fi network doesn't stop at the walls of your home or office. It can extend more than 300 feet from your wireless gateway, so people outside your home may be able to access your Wi-Fi network. If they do, they could:
  • Monitor the websites you visit
  • Copy your usernames and passwords
  • Read your email and other messages
  • View files on your computer
  • Infect your computer with a virus
  • Send spam or perform illegal activities
  • Slow down your computer and your internet connection speed

Steps to take to secure your network

Make sure Wi-Fi network security is turned on

To properly protect your network, be sure to enable network security. This means entering a Wi-Fi password to connect to your network. Have one of our gateways?

Heads up: If you didn’t get your modem from us, check the manufacturer's manual for instructions.

Use firewall and antivirus software

Install antivirus and firewall software on each computer that can access your network. Update this software regularly for the best results.

Change the device access code on your gateway

Gateways and modems have a default device access code. Anyone who has this code can access your gateway and change your settings, including the network password. For an extra layer of protection, be sure to change your device access code.

Hide your Wi-Fi network name

Your Wi-Fi network name shows up whenever anyone searches for available networks in your area. Hiding the name makes it harder for others to hack into your network and prevents them from connecting to your network accidentally.

Try advanced security options
