Chapter 3: Configuration

In order to access the Internet through the router, you must check the TCP/IP settings before configuring the router.

Step 1: Configure TCP/IP on Client PC

To access the ADSL Router via Ethernet, the host computer must meet the following requirements:

With Ethernet network interface.

Must have TCP/IP protocol installed.

Set client PC with obtain an IP

address automatically.

With a web browser installed: Internet Explorer 5.x or later.

The ADSL Router is configured with the

default IP address of 192.168.1.1

and subnet mask of

255.255.255.0.

As t

DHCP server is

Enabled

by default,

the DHCP clients should be able to access the

ADSL Router.

you could assign an IP address to the host PC first for initial configuration.

You also can manage the ADSL Router through a web browser-based manager:

ADSL ROUTER CONTROL

PANEL

. The ADSL Router manager uses the HTTP protocol via a web browser to allow you to set up and manage

the device.

To configure the device via web browser, at least one properly configured PC must be connected to the network
(either connected directly or through an external hub/switch to the LAN port of the device).

If TCP/IP is not already installed, follow the steps below for installation.

Note:

Windows 98 SE users need the

Windows 98 SE installation CD-ROM

to complete the

installation!
