Introduction

Find your wireless gateway's username and password (Network Key).

Overview

If you have the Wireless Gateway (model number TG852G, TG862G, SMCD3DNV or TC8305C) or Wireless Gateway 2 (model number DPC3939), you can find your Wi-Fi Network Name (SSID) and Password (Network Key) on a white label on the bottom panel of your device. 
Information panel on the bottom panel of a wireless gateway, with network name, encryption and network keys, and WPS PIN.

If you have changed the default information and no longer have the new network name or password, you can easily retrieve them by following the steps below. You do not need to factory reset your wireless gateway.

How to Find or Change Your Network Name and Password

  1. Choose a laptop or Wi-Fi device that is currently connected to your network. If none of your devices are connected, use an Ethernet cable and connect a computer or laptop directly to your wireless gateway.
  2. Open a web browser and go to the Admin Tool (http://10.0.0.1) – this is the wireless gateway's administration site. The default settings are:
    • Username: admin
    • Password: password (case-sensitive)
      Admin tool login with two fields to fill out. One for Username, one for Password, then a LOGIN button at the bottom of the window.
       
    • Note: If you changed your Admin Tool password previously, you will need to use your new login information. If you don’t remember your Admin Tool password, you will need to factory reset your wireless gateway. Instructions on how to do this can be found by reviewing the wireless gateway user guides at Wireless Gateway User and Quick Start Guides.
  3. On the left navigation menu, select Gateway, then Connection and then Wi-Fi.

    • On this page, you can also edit your wireless network information, including changing your name or password. If you make any changes, remember to click SAVE SETTINGS.
  6. Now that you have your Network Name (SSID) and Password (Network Key), you can connect your Wi-Fi devices to your network.
  7. If you have changed any information, use the new information to reconnect all your Wi-Fi devices to your network.
