WiFi Network Name and Password

The preassigned WiFi network name (SSID) and password (network
key) are unique to your modem router, like a serial number. Because the
modem router automatically uses WiFi security, you don’t need to set it
up. The WiFi settings are on the label on the modem router.

We recommend that you use the preassigned WiFi settings because
you can check the label if you forget them. You can also log in to the
modem router to change these settings. If you do so, write down the new
WiFi settings and store them in a safe place.

You can write the WiFi settings from the label on your modem router in
this space for easy reference. If you change the WiFi settings, write the
new settings here for easy reference and store this booklet in a safe place.
