Hello, im using a laptop with windows vista and a computer windows 7 ultimate. Recently, my laptop became unable to use the internet. I cannot go to google or any other website whether i am using internet explorer of mozilla firefox, neither am i able to sign into windows live messenger. Wireless network connection says it is connected, and the network diagnostics do not detect any problem with my internet. The funny thing is i am able to use the internet well with my Windows 7 pc!! please help me thank you:)
