This article will step you through the process of changing your WiFi password on a Cisco (DPC3848V or DPC3825) modem. To do that, you'll need to log in to the modem and change settings in its admin console.
Set a new password
Open a web browser.
Enter "192.168.0.1" in the address bar.
Enter the username "cusadmin" (lowercase).
Enter the current password (Pre-Shared Key, case sensitive) found on the white sticker on your modem.
Click Wireless at the top of the page.
Click the Wireless Security tab.
Under 2.4GHz Wireless Security, type a new password for the network in the Pre-Shared Key field.
Under 5GHz Wireless Security, type a new password for the network in the Pre-Shared Key field.
Click SaveSettings before closing the window.
Restore default password
If you would like to restore the default password, you can perform a pin-hole reset. This will restore all of the default settings, including the WiFi channel and network name.
Locate the small pin-hole reset button on the back of your Shaw modem.
Push and hold the button with a paperclip or pin and hold for 15 seconds.
The lights on the modem will begin to flash if the reset was successful.
