New Vostro 230 running Windows 7 pro. Connects to Air Port extreme router via either net cable but will not connect to internet. Tried troubleshooting software on Windows finding no problems. Tried turning off firewall with no results. Tried connecting directly to modem with no results. Tried rebooting modem and computer with no results. Cable connect works with other computers. Any help or ideas will be appreciated. Thanks
Thank you for using the Dell Community Forum.
Here is some information that my help you resolve the wired internet connection.
Network and Sharing Center; in Windows 7, click
Change Adapter Settings, and in Vista, click
Manage Network Connections.
Local Area Connection. In the
Local Area Connection Statusdialog box that appears, click
Internet Protocol Version 4 [TCP/IPv4], and then click
Use the following IP address, and enter the IP address of your computer.
Advanced..., and then select the
Add...to add a new DNS server.
Add...again, and type a second domain.
Add..., and then enter the correct primary WINS number. Click
Add...again, and enter the secondary WINS number.
Here is a link from the internet I also found that may be helpful.
