Networking Basics

Check your IP address

After you install your new D-Link 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 on the

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® 7 - Click on

Start

>

Control Panel

>

Network Connections

.

Windows® Vista - Click on

Start

>

Control Panel

>

.

Windows® 2000 - From the desktop, right-click on

My Network Places

Properties

.

Step 2

Right-click on

Local Area Connection

which represents your D-Link network adapter and select

Properties.

Step 3

Highlight

Internet Protocol (TCP/IP)

and click on

Properties

.

Step 4

Click on

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 the Default Gateway the same as the LAN IP address

of your router (192.168.0.1).

Set the 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.

Step 5

Click on

OK

twice to save your settings.
