Router Maintenance

This article introduces the basic operations that will help the reader to get started with Vigor Router.



Router's GUI

Vigor Router uses a web-based user interface (WUI), the graphical user interface (GUI) can be accessed via a web browser. If the router is in its default configuration, you may follow the steps below to access the router's GUI:

  1. Power on the router.
  2. Connect a PC to router's LAN port by an Ethernet cable.
  3. Ensure the network interface of the PC is “Obtaining an IP Address Automatically”. (For Windows PC, this can be configured at Control Panel > Network and Sharing Center > Change Adapter Settings, right-click on the network adapter and go to Properties > TCP/IPv4 Properties.)
  4. On the PC, open a web browser, type “” in the address bar, and hit “Enter”. You should see the router's login page.
  5. Enter the default username and password (which are both “admin” by default for most of the models), and click “Login”. Then you are logged into the router's management page.


Change the Default Password

The default username and password to log in the router can be found in User Guide. For most of the Vigor Routers, the default username and password are both “admin”. For security concerns, after you log in the router for the first time, it is highly recommended to change the password. This can be configured at System Maintenance >> Administrator Password Setup page.

However, please keep in mind that once the password is changed, there's no way to recover it without logging in the router. If the login password is lost, there is no master key to gain access to the router, either, we'll have to reset all the router's settings to factory default, and then log in the router with the default password. Therefore, it is recommended to write down the password and keep it in a safe place.



Configuration Backup & Restore

The router's configuration are stored as a “CFG file”, we may download the file from the router and save a copy of the current configuration, so that if changes are made afterward, we may easily reset the router back to its previous state; on the other hand, we may also apply the CFG file to other devices, thus to copy the same configuration to another router. 

The CFG file can be downloaded from System Maintenance >> Configuration Backup page, and restoring a CFG file to the router can also be done on the same page.


Firmware Upgrade

It is important to always keep the router's firmware version updated to the latest version. This can ensure the router gets all the new features, as well as the latest fixes and improvements. The current firmware version can be checked in “System Information” on the router's dashboard, the built date of the firmware is shown as well. The latest firmware version can be found on DrayTek Homepage (www.draytek.com) > Download > Firmware. For other/older firmware versions, you may visit DrayTek official FTP Server at ftp.draytek.com.


Types of Firmware Files

The file you download from DrayTek Homepage will be a zipped file. Unzip the file and there will be a folder which contains two files with the same file name but different file extension: “.all” and “.rst”. The “.all” file is the normal firmware file, the “.rst” file is the same firmware file but with factory default settings. Use the “.all” file for regular firmware upgrade, and use “.rst” file when you would like to reset the router to its factory default settings while doing a firmware upgrade.

For xDSL models, there probably will be two or more firmware files to download, Those files are the same firmware file except that they use different modem codes for the DSL connection, this might affect the performance of ADSL/VDLS connections. If not sure which one works best, we would recommend the standard version (00, STD, or the one with the smallest number) first. (Learn more about What is the difference between firmware files?)


Upgrade Firmware from GUI

After you have the new firmware file ready, you may perform the firmware upgrade from router's GUI by going to System Maintenance >> Firmware Upgrade, select the file you just downloaded, then click Upgrade. Make sure the connection is stable while the file is loading. The upgrade will be done after a few seconds, and the router will reboot after the firmware update complete.


Upgrade Firmware by TFTP

The firmware can also be loaded to the router via TFTP (Trivial File Transfer Protocol). This is the method to update the firmware without the access to router's GUI, it is faster and also very useful when the router is not responding due to a destroyed firmware. For detailed instructions, visit How to upload firmware to my router via TFTP? or How to upload firmware via TFTP on macOS?

Collecting Syslog

Syslog is a message generated by the router to show the error logs as well as the general information, which are useful information while trouble -shooting. To have a quick view of syslog, go to Diagnostics >> Syslog Explorer from router's GUI. Check “Enable Web Syslog” and select the “Syslog Type” you want, the router will start to show the syslog. To save the logs, click “Export” on the top. However, due to the limited memory of the router, this will be just a simplified version of syslog. To have the complete information, we suggest saving the syslog to a USB flash drive or using Syslog Utility. For more details, visit How to collect router's syslog?
