Windows 7: Only a Dell Laptop does not connect to the Internet

Only a Dell Laptop does not connect to the Internet

I have Sky broadband at my home and everything was working perfectly till yesterday.

I was able to connect wireless ly to the internet. Yesterday, my main laptop, running Windows 7 64 bit, started showing an Exclamation (!) sign on top of the signal strength indicator. On mouser over, it says "Unidentified Network". However, all my other laptops were still connected to the internet.

Even the same laptop when I boot in Ubuntu works fine. I have tried disabling and enabling the Network adaptor multiple times but nothing changes. On the laptop that works, I logged onto the router interface and it shows the non working laptop as connected but it shows it as "Unknown".

Can anyone please suggest what could possibly be wrong? I checked the TCP/IP settings and they are same across laptops.

Update: I have tried the following command "netsh winsock reset". The situation hasn't improved but on mouseover, the message is now "No Internet Access"
