System

There are five items within the System section:

Time Zone, Firmware Upgrade, Backup/

Restore, Restart and User Management.

Time Zone

The router does not have a real time clock on board; instead, it uses the Simple Network Time

Protocol (SNTP) to get the most current time from an SNTP server outside your network. Choose

your local time zone from the drop down menu. To apply the selected local time zone, click Enable

and click the Apply button. After a successful connection to the Internet, the router will retrieve

the correct local time from the SNTP server you have specified. If you prefer to specify an SNTP

server other than those in the drop-down list, simply enter its IP address in their appropriate blanks

provided as shown above. Your ISP may also provide an SNTP server for you to use.

Firmware Upgrade

Your router’s “firmware” is the software that allows it to operate and provides all its functionality.

Think of your router as a dedicated computer, and the firmware as the software that runs in your

router. Thus, by upgrading the newly improved version of the firmware allows you the advantage to

use newly integrated features.

Click on Browse to select the new firmware image file you have downloaded to your PC. Once the

correct file is selected, click Upgrade to update the firmware to your router.

51

Backup / Restore

These functions allow you to save a backup of the current configuration of your router to a defined

location on your PC, or to restore a previously saved configuration. This is useful if you wish to

experiment with different settings, knowing that you have a backup in hand in case any mistakes

occur. It is advisable that you backup your router configuration before making any changes to your

router configuration.

Press Backup Settings to select where on your local PC you want to store your setting file. You

may also want to change the name of the file when saving if you wish to keep multiple backups.

Press Browse… to select a file from your PC to restore. You should only restore your router setting

that has been generated by the Backup function which is created with the current version of the router

firmware. Settings files saved to your PC should not be manually edited in any way.

Select the settings files you wish to use, and press Update Settings to load the setting into the

router.

52

Restart

There are 2 options for you to choose from before restarting the your 7800 device. You can either

choose to restart your device to restore it to the Factory Default Settings or to restart the device

with your current settings applied. Restarting your device to Factory Default Setting will be useful

especially after you have accidentally changed your settings that may result in undesirable

outcome.

After selecting the type of setting you want the device to restart with, click the Restart button to

initiate the process. After restarting, please wait several minutes to let the selected setting applied

to the system.

User Management

In order to prevent unauthorized access to your router configuration interface, it requires all users

to login with a username and password. Therefore only system administrator can access the

system. It is highly recommended that you change your password upon receiving your router. The

default password is “admin”.

To change your password, simply enter the old password in the Old Password blank. Then enter

your new password in the New Password and Confirm Password blanks provided. When this is

done, press Apply to save changes.
