My current network setup is as follows: A router connected to an ADSL line directly with 4 slots (2 Desktops + 2 free slots). End of last year, I was still able to use the internet with my Inspiron 640m (Vista). I went overseas then for about a month and never connected to any network until I came back. Upon connection, I don't get any Internet connection. The other desktops connected to the same router, as do other laptops connected to it are still able to connect to I assume there's not problem with the router. No ipconfig /renew or whatever could work. I've contacted Dell and tried every possible solution they suggested to no avail. They even changed the motherboard and says its not the hardware.

 

I ran ipconfig and this is what appears:
