I have a Windows Vista computer which i have used for about 2 years without any issues. Recently, i started having problems connecting to the internet with this Vista computer. My other XP Computers are fine and can connect to the Internet.
Regardless of wired or wireless connection, i am unable to get the Vista computer connected to the web. The Status remains "Limited" for IPv4 and IPv6. It also shows unidentified Public Network, and is able to connect to the router. However, there's a disconnection between the router and the internet.
Any help will be greatly appreciated, i have been on this for 4 weeks now.

I would skip some troubleshooting on this and just reset the tcp/ip stack. If that doesn't work then start toubleshooting.
Use a manual method to reset TCP/IP
To open a command prompt, click Start and then click Run. Copy and paste (or type) the following command in the Open box and then press ENTER:
cmd
At the command prompt, copy and paste (or type) the following command and then press ENTER:
netsh int ip reset
Reboot the computer.
Basic troubleshooting.
Can you ping the router? If so the connection to this is ok.
Can you ping other computers on the network by their computer name or by IP Address? If so then your router is servicing internal requests ok
Can you ping 173.194.36.104 - Google's IP address. - If so outside connections are ok. Can you ping If so then your DNS server is working.
If you can do all this then I would test if you can use another browser.
Also check that no proxy setting have been put in place. Opera doesn't use the default ones shared by IE, FF and Chrome. Maybe try that.
If all that fails comment back and we'll go on to more advanced things.
