Updating the firmware/software on networking equipment is essential. Firmware/Software patches can update hardware drivers and/or patch software bugs. These update can enhance the performance of the device or provide better security to help keep data flowing through it secure.
Before uploading any firmware patch on a VMG device please verify that you are using the correct patch revision. Updating the incorrect patch may cause service issues. For example: if your VMG device is running firmware version 1.00(AAFR.0)C0, only update it with other AAFR patches.
Firmware for the Zyxel VMG product can be downloaded from ftp://ftp.zyxel.com. Please keep in mind when looking for firmware patches that the VMG, if provided by the internet provider, may contain ISP specific software. The ISP would need to be contacted to receive the latest patch to their proprietary software/firmware versions. Contact tech support at 800-255-4101 option 5 if you need assistance on figuring out whether your VMG product has ISP proprietary firmware or Zyxel original.
Accessing the Web Configurator
To access the device web configuration screen to configure the modem/router, please connect your computer directly to an available LAN port. A wired computer is needed to minimize downtime when making changes to the configuration. During the configuration process the device may reboot to apply changes successfully, this means a temporary loss of connection to the network, this is why it is not recommended to make any configuration changes via wireless.
Open an internet browser (Internet Explorer, Mozilla Firefox, Google Chrome, etc.) and delete the contents of the address bar. Type http://192.168.1.1 on the address bar and hit the enter/return key on the keyboard. 192.168.1.1 is the ZyXEL default IP address, if your VMG was provided to you by the internet service provider it may be running proprietary firmware/software based on your provider's standards for operation. If this is the case you may need to contact the service provider to obtain the IP address for the web configurator and login credentials (administrative credentials). Once the correct web configurator address is entered on the browser, the following screen will appear requesting the administrator credentials.
Enter the Zyxel administrative credentials: username=admin & password=1234
Or, enter the ISP proprietary administrator credentials: must be obtained from the ISP
After the Zyxel default credentials are entered a prompt will appear to create a new admin password. Create a new password the press the Apply button to save the settings, or, check the box "No need to change password. Do not show this page next time" and click Apply to keep the default password.
To upgrade the firmware on the VMG device please mouse over the Maintenance menu and select "Firmware Upgrade" from the list.
In the firmware upgrade menu click the Browse button to search for the software patch downloaded to your computer. Once the correct patch is selected click Upload on the far right to begin the firmware upgrade procedure. Process takes about 5 minutes to complete, internet traffic will seize to work during updating.
