System

There are six items within the

System

section:

Time Zone, Remote Access, 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 current time from an SNTP server outside your network. Choose your

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 list, simply enter its IP address as

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

Daylight Saving

is also known as

Summer Time Period.

Many places in the world

adapt it during

summer time to move one hour of daylight from morning to the evening in local standard time.

Check

Automatic

box to auto set your local time.

Resync Period

(in minutes) is the periodic interval the router will wait before it re-synchronizes the

router’s time with that of the specified SNTP server. In order to avoid unnecessarily increasing the

load on your specified SNTP server you should keep the poll interval as high as possible – at the

absolute minimum every few hours or even days.

Remote Access

To temporarily permit remote administration of the router (i.e. from outside your LAN), select a time

period the router will permit remote access for and click

Enable.

You may change other

configuration options for the web administration interface using

Device Management

options in

the

Advanced

section of the GUI.

If you wish to permanently enable remote access, choose a time period of 0 minutes. This setting

cannot be saved into flash when timer set to zero.

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 it runs. Over time

this software may be improved and modified, and your router allows you to upgrade the software it

runs to take advantage of these changes.

Clicking on

Browse

will allow you 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 in your router.

53

DO NOT power down the router or interrupt the firmware upgrading while it is

still in process.

Improper operation could damage the router.

Backup / Restore

These functions allow you to save and backup your router’s current settings to a file on your PC, or

to restore a previously saved backup. This is useful if you wish to experiment with different settings,

knowing that you have a backup handy in the case of any mistakes. It is advisable to backup your

router’s settings before making any significant changes to your router’s configuration.

Press

Backup

to select where on your local PC to save the settings file. You may also 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 settings files that

have been generated by the Backup function, and that were created when using the

current

version

of the router’s firmware.

Settings files saved to your PC should not be manually

edited in any way.

After selecting the settings file you wish to use, pressing

Restore

will load those settings into the

router.
