ZYXEL VMG8825-T50 (02) PDF Document

The default login details for your ZYXEL VMG8825-T50 are as follows:

Follow these steps to access the Web Configurator for your ZYXEL VMG8825-T50:

1. Make sure your ZYXEL VMG8825-T50 hardware is properly connected.

2. Launch your web browser. If you are not automatically re-directed to the login screen, go to http://192.168.1.1.

3. A password screen will display. Select your preferred language.

4. To access the administrative Web Configurator, type the default username ‘admin’ and the randomly assigned default password (found on the device label) into the password screen and click Login. If you have previously changed the password, enter your new password and click Login.

5. The first time you log in, a screen will prompt you to change the password. Enter a new password, retype it to confirm, and click ‘Change password’. If you prefer to keep the default password, click ‘Skip’.

To make your ZYXEL VMG8825-T50 more secure and manage it more effectively, you should regularly do the following:

• Change the password. Use a password that is not easy to guess and that consists of different types of characters, such as numbers and letters.

• Write down the password and put it in a safe place.

• Back up the configuration. Restoring an earlier working configuration may be useful if the device becomes unstable or crashes. If you forget your password, you will have to reset the device to its factory default settings. A backed-up configuration file allows you to simply restore your last configuration without re-configuring everything from scratch.

If you forget your password or cannot access the Web Configurator, you will need to use the RESET button to reload the factory-default configuration file. This will erase all configurations that you had previously. The password will be reset to the factory default (see the device label), and the LAN IP address will be “192.168.1.1”.

1. Make sure the POWER LED is on (not blinking).

2. To set the ZYXEL VMG8825-T50 back to the factory default settings, press the RESET button for more than five seconds or until the POWER LED begins to blink, and then release it. When the POWER LED begins to blink, the defaults have been restored and the device restarts.
