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 and type cmd in the Search box. On older versions
of Windows, click Start > Run. In the run box type cmd and click
OK.
At the prompt, type ipconfig and press Enter.
It will display the IP address, subnet mask, and the default
gateway of your adapter.
If the address is 0.0.0.0 or empty, 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.
