normally, all router are connected via rj45 from your adsl modem. i haven't seen any wifi router that connects to your pc thru a USB port (atleast here in singapore except if given by the dsl provider). if you are using a wi-fi router and your pc (desktop or laptop) don't have the wi-fi card better buy a wireless card otherwise get rj45 and connect to your lan card.

i haven't seen globe router yet but perhaps its a modem/router combo that is why it can be connected to USB.
