I own 2 D-Link USB wireless adapters and use them in my home. Make sure you installed the drivers that came on the included cd. Windows XP does not have drivers. Second you might tell me what wireless router you are using. Down by your time you will see to screens flashing, right click and click "view available wireless networks", you should sse the name of your router. Click on the name of the router the click the connect button. If you are not using WEP (password) then click the box that says "allow me to connect even if it is not secure" or something to that effect. Once it tells you connect to that router it will give you a signal strength status such as excellent or good. Now try IE and bring up a web page. That is the short of it so try that if it still doesn't work we can get into the long of it. BTW what OS are you using?
