How do I share my Wi-Fi network name and password with guests?


Wi-Fi network security

Your Wi-Fi network may extend more than 300 feet from your Wi-Fi gateway. This means that 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

Turn Wi-Fi network security on

To properly protect your network, be sure to enable network security. This means entering a Wi-Fi password to connect to your network.

Change the device access code on your gateway

Gateways and modems have a default device access code. Anyone with 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 the area. Hiding the name makes it harder for others to hack into your network.
