Hopefully this should work ok:
Firstly is the wireless card turned on ? if not try FN+F2 (i think)
If no joy goto Control panel in the host pc and select the wireless network setup wizard and follow the prompts...you will need a pen/flash drive but can also be done with a memory card,but obviously you would need a card reader.
This will carry all settings across to the laptop.
Just a thought,check your wep/wpa security key also.
