Chapter 3: Getting to Know the Wireless-G Broadband Router

The Back Panel

The Broadband Router's ports, where the cables are connected, are located on the back panel.

Reset Button

There are two ways to reset the Broadband Router's factory defaults. Either press the 

Reset 

Button

, for approximately ten seconds, or restore the defaults from the Password tab in the 

Broadband Router's Web-Based Utility.

Internet

The 

Internet

 port is where you will connect your broadband Internet connection.

1, 2, 3, 4

These ports (1, 2, 3, 4) connect the Broadband Router to your networked PCs and other 
Ethernet network devices.

Power

The 

Power

 port is where you will connect the power adapter.

 

Important:

 Resetting the Broadband Router 

will erase all of your settings (WEP Encryption, 

Wireless and LAN settings, etc.) and replace 

them with the factory defaults. Do not reset 

the Broadband Router if you want to retain 

these settings.
