Connect a LAN cable from the D-Link to your laptop/computer's LAN port, open the browser on your laptop/computer and enter the D-Link's configuration URL..

The default login = admin
The default PW = blank (just press Enter) You can now change the default admin password.
You can now configure the wireless settings. (SSID, WPA or WPA2 encryption to protect your wireless network and Internet from unauthorized access). Now configure the wireless card in your computer/laptop with the router's wireless settings.

Wireless connections have a lot in common so here is a link that will give you the general configurations for a wireless Router to PC. Keep in mind that you will need to configure both the computer and the router in two separate steps. That is why it is best to use the setup disk that normally comes with a new piece of equipment and the cables.

Also keep in mind that the equipment should be matched or designed to work with the other equipment. You will have some kind of a modem either a cable modem or internal modem or external modem that the router will have to connect to.

It is best to allow your own Internet Service Provider to set up the connections. They may not be able to support the configuration if you do not purchase it from them and then you will need to do-it-yourself.

Here are the links for configuring the computer with the different operating systems

Win XP http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/wlan_client_configure.mspx?mfr=true
Win Vista

If you can connect to the internet using the Ethernet cable on your laptop then the cable modem is configured correctly.
If you want to connect to the Internet using the D-Link wireless router then first you need to configure the D-Link wireless settings and then configure the wireless card in your laptop with the D-Link's wireless settings. Remove the Ethernet from the laptop and connect it to the WAN/Internet port on the D-Link wireless router.

If you want to use Windows Wireless Zero Configuration to manage the wireless network, you will need to have Windows XP with service pack 2 as a minimum.

With Windows XP and SP2, you will need a Microsoft update for WPA2 that can be obtained from:

http://support.microsoft.com/kb/893357/en-us

After installation you will need to use the Windows Zero Config wireless configuration in the control panel to configure the adapter. WPA2 should now be available and work correctly.

Windows XP with Service Pack 3 and Windows Vista offer support for WPA2 without additional updates.

To use a wireless network/connection you need to do.
1. Configure the router's wireless with SSID, WPA encryption etc.
2. Next configure the wireless card in the computer/laptop with the router's wireless settings so it can connect to the wireless router.
Please click on this link for my instructions on how to secure your wireless network, configure the wireless router and configure the wireless card in the computer/laptop :-

Unplugging the wireless router and connecting it again should not have altered the wireless connection/configuration. You have connected the cables correctly because the Internet works when you connect a LAN cable to the router.
The Linksys wireless configuration or the wireless card configuration in the computer was changed it to lose the wireless connection. The wireless card configuration needs to be changed to match the wireless router's settings or change the Linksys with new configuration settings and configure the wireless card accordingly.

I may be able to help with this...but I need a detailed description of how you have things connected between the XP desktop, the cable, modem, the Linksys router, and the laptop. Also, is the Linksys router new?

Typically, the wan port on the wireless router connects directly to the cable modem with a cat5 network cable....then the desktop pc connects to the router...on port 1 for example...with a similar cable. Once the wireless router is set up properly, the laptop should then be able to connect using wireless.
