No Internet Connection on Vista

I have a vista computer that won't connect to the internet. The Ipv6 is on limited and the Ipv4 is on local. When I click diagnose it says I need to: reboot the modem or router, get new IP settings, or reset the network adapter. I have done all of them. I also tried disabling Ipv6. It still does not work. I get an internet connection on all of my other computers. How can I fix this?

Use the Network Setup Wizard to add the computer to your network, make sure that it is in the same workgroup as the others...

Where is the the network setup wizard?

its under control panel and network and sharing center and there will be options near bottom to create a new connection which launches the wizard

Hello,

Is this a wired or wireless connection issue?

If it's a wireless issue, for now please remove the network encryption from the router, then see if you're able to connect. You also try a lower Security which is WEP.

If the above suggestion didn't work for you pls post an ipconfig /all:
Click on Start => in run or search box type cmd, enter. Open up a command prompt then Copy and Paste these ipconfig /all >c:\ipconfig.txt . Please attach the .txt file to be found in your Local Disk 'C' on your next post.

Please let us know.
