Check Your IP Address

After you install your new D-Link adapter, the TCP/IP settings,

by default should be set to

Obtain an IP address from a DHCP

server automatically

. To verify your IP address, please follow the

steps below.

Click

Start

Run

. In the run box type

cmd

and click

. 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.
