Quick Installation Guide

Changing Administrator Password

It is highly recommended to change the administrator password used to access 
the web-based interface of the router upon initial configuration. This helps you 
to improve your network security.

1. Go to the 

System / Administrator password

 page.

2. Enter a new password for the administrator account in the  

Password 

and 

Confirmation

 fields.

3. Click the 

Save 

button.

!

Remember   or   write   down   the   new   password   for   the   administrator 
account. In case of losing the new password, you can access the web-
based  interface  of  the  router  only after  restoring  the  factory  default 
settings via the hardware Reset button. This procedure wipes out all 
settings that you have configured for your router.

Saving Settings to Non-volatile Memory

In order to avoid losing the new settings upon hardware reboot (accidental or 
intentional power-off of the device), it is recommended to save the settings to 
the non-volatile memory of the router.

Click the 

Save&Reboot

 line in the top-page menu displayed when the mouse 

pointer is over the 

System

 caption.

Wait until the router is rebooted. Now you can use it to access the Internet or 
access the web-based interface of the router to configure additional parameters 
(for  detailed description of every page of the web-based interface,  see  the 

User Manual

” document).
