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.
