Fresh Window 7 Ultimate Installation but no available connections  

Good day everyone!

My friend installed a Fresh Copy Of Windows 7 and everything was very successful but something bad happened. When he attempted to connect to his internet/wifi, this came up "No Internet Connection Is Available". After that he open up the device manager, and found

NETWORK ADAPTERS
|- Bluetooth Device (Personal Area Network)
|- Bluetooth Device (RFCOMM Protocol TDI)

OTHER DEVICES
|- Ethernet Controller
|- Network Controller
|- SM Bus Controller
|- Universal Serial Bus (USB) Controller
|- USB 2.0 CRW

Note: All of the devices under "OTHER DEVICES" have a yellow exclamation mark

Here are some important information about my friend's computer
- Model Number: Notebook NP355E4X
- Previous Windows Installed: Window 8 consumer preview
- Hard Drive: 320GB S-ATAII Hard Drive (5,400RPM)
- Graphics: AMD Radeon™ HD 7310 Graphics
- ISP: Belkin

Can anyone please help! I am really helpless....

Thanks for your reply but
I've went to samsung website but sadly, there is no driver downloads except a SW update which claim to install drivers automatically

WOW! I am very amaze to see people helping me out in such a short time thats really very impressive

But back to the topic, the swupdater is great but i am not sure does it require internet.....and also,thanks for the driver list provided but i am not sure which driver to choose from..

By the way my friend don't have internet access

Oh so for my current situation, what should i be downloading?
Thank you!
