    5. Save the changes and reboot your router.

Important Considerations When Changing the IP Address:

  • Subnet Mask: Ensure the subnet mask remains the same (usually 255.255.255.0 for a typical home network).
  • DHCP Server: If you change the router’s IP address, you may need to adjust the DHCP server settings to ensure it assigns IP addresses within the new range.
  • Conflicts: Avoid choosing an IP address that is already assigned to another device on your network. This can cause IP address conflicts and connectivity problems.

Security Best Practices for Your Xfinity Comcast Router

Protecting your home network is crucial. Here are some essential security best practices:

  • Change the Default Password: The most important step is to change the default username and password immediately after setting up your router. Use a strong, unique password that is difficult to guess.
  • Enable WPA3 Encryption: Use the strongest encryption protocol available (WPA3 if supported, otherwise WPA2). This encrypts the data transmitted over your Wi-Fi network, making it harder for unauthorized users to eavesdrop.
  • Enable the Firewall: Your router has a built-in firewall. Ensure it’s enabled to protect your network from external threats.
  • Update Firmware Regularly: Keep your router’s firmware up-to-date to patch security vulnerabilities.
  • Disable Remote Management (If Not Needed): If you don’t need to access your router’s settings remotely, disable remote management to prevent unauthorized access from the internet.
  • Enable Guest Network: Use a guest network for visitors to isolate their devices from your main network. This prevents them from accessing your personal files or other sensitive information.
  • MAC Address Filtering (Use with Caution): You can restrict access to your network based on the MAC addresses of devices. However, this can be cumbersome to manage and is not foolproof, as MAC addresses can be spoofed.

By following these security best practices, you can significantly enhance the security of your Xfinity Comcast home network and protect your data and devices from unauthorized access.
