Your WiFi password can be changed on the web portal. Access the web portal by logging into your CenturyLink router.
Once you've logged into the Century Link router, navigate to the following location:
- Go to Wireless Setup
- Choose 2.4 GHz
- Click Wireless Security
On this screen, you can set a new network name (SSID) or WiFi password (passphrase/network key).
Once you've set new WiFi information, save the changes and test the new wireless connection.
