JoeBoca65,
Are you using Mac Address filtering in your wireless router? If yes, turn if off or allow the ip address past your filtering.
Is your SSID hidden? If yes, allow your SSID to be shown.
If your system in under warranty, you can continue with DELL-Amogh G and he can also assist you. I work with the Dell Employees and sometimes two heads are better than one.
What virus program do you have installed?
Start, control panel, network and sharing center. Take a screenshot and save it to paint, then post it back here.
Start, control panel, network and sharing center, click on properties. Look for TCP/IPv4 and TCP/IPv6 and click on properties for each. Have your settings match mine.
