Once you've logged into the web portal, look for security settings. You may need to scroll down or check the sidebar depending on the exact model of your router. The field we're looking for is labeled "Pre-shared key".
Enter the new WiFi password in the "Pre-shared key" field. Making the password more complex will be safer than using a simple one. Consider using a few rules when creating a new password. For example:
- Avoid using dictionary words.
- Use numbers and special characters.
- Use uppercase and lowercase letters.
Enter the password again if asked to confirm the new key.
Click Save once the new password has been entered. Once the changes have saved, restart your Arris device, and test the new WiFi password.
