Need USB net

Hi
I am having a laptop ,PC and N-WiFi router.
I am using cable net whose wire goes into WiFi router. my laptop has wifi in-built and hence i use net on lappy.

Now i need to use same net on PC with out having any physical wiring done.

I think i can use USB-WiFi device. can any one suggest me good USB N-WiFi device for same ?


thanks.

My mobo is Intel H67BL which lacks WiFi on-baord
