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.

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 192.168.1.1, make your IP address 192.168.1.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 (192.168.1.1).
Set Primary DNS the same as the LAN IP address of your router (192.168.1.1). The Secondary
DNS is not needed or you may enter a DNS server from your ISP.
