I'm not sure what you are asking, but I'll try and guess that you want to connect to your DLink DIR-628 wireless router, that has been properly configured to your cable modem/DSL modem by a professional.
If you are running Windows XP, Follow these steps:Start~>Control Panel~>Network Connections
You will then see your network connections, look for your wireless adapter, right click on it, then select properties. Look at the tabs and select Wireless networks. In this tab, you can configure what your SSID (the name of you network) and your password, and encryption, etc. Once you fill out the required information then voila! You connected.
I hope this helps:)
