Setting up wifi with asus mobo adaptor

OK so this is the first time i set up a wireless lan, therefore i am bound to make a mistake somewhere. Theres this adaptor which can create a wifi connection, and i got the software installed, my laptop can see it, get an IP but something about DNS is missing. The wireless connections setup gets a default IP but i just make it obtain one automatically. Also, on my PC it says that my wireless con has limited or no connection, but since its suppose to work as the accesspoint i guess it doesnt matter. I got the lan cable inset.
 Couldnt find any help over at asus' or google...  KTHXBY
