Win7 hangs while connecting to my internet connection

[Psychosocial]

I have got Win7 Ultimate 32 Bit. I have it up for quite a time but this is the first time I am facing this weird problem. Whenever I try to connect to the internet, my PC hangs at the 'Registering your computer on the network' window. I can't do anything then and I have to just manually restart my system. I am currently on Ubuntu posting this. Anyone has any clue about this problem ? Help will be obviously appreciated.

It might be a driver related issue. You can try updating your LAN driver.
