Check your IP address

After you install your network adapter, by default, the TCP/IP settings should be set to obtain an IP address from a

DHCP server (i.e. wireless router) automatically. To verify your IP address, please follow the steps below.

Click on

Start

>

Run

. In the run box type

cmd

and click

OK

.

At the prompt, type

ipconfig

and press

Enter

.

This will display the IP address, subnet mask, and

the default gateway of your adapter.

If the address is 0.0.0.0, check your adapter

installation, security settings, and the settings

on your router. Some firewall software programs

may block a DHCP request on newly installed

adapters.

If you are connecting to a wireless network at a

hotspot (e.g. hotel, coffee shop, airport), please contact an employee or administrator to verify their wireless network

settings.

Statically Assign an IP address

If you are not using a DHCP capable gateway/router, or you need to assign a static IP address, please follow the steps

below:

Step 1

Windows

®

2000: Click on

Start

>

Settings

>

Control Panel > Network Connections

Windows XP: Click on

Start

>

Control Panel > Network Connections

Windows Vista

: Click on

Start

>

Control Panel > Network and Internet > Network and Sharing Center > Manage

network connections

Step 2

Right-click on the

Local Area Connection

which represents your network adapter and select

Properties

.

Step 3

Highlight

Internet Protocol (TCP/IP)

and click

Properties

.

Step 4

Click

Use the following IP address

and enter an IP address that is on the same subnet as your network or the LAN

IP address on your router.

Example: If the router’s LAN IP address is 192.168.0.1, make your IP address 192.168.0.X where X is a number between

2 and 99. Make sure that the number you choose is not in use on the network. Set Default Gateway the same as the

LAN IP address of your router (192.168.0.1).

Set Primary DNS the same as the LAN IP address of your router

(192.168.0.1). The Secondary DNS is not needed or you may

enter a DNS server from your ISP.
