Okay so i am saving up for a macbook and i was just trying to find out how wireless internet works. We only have one computer with internet (PC) and it just has a regular cable modem, its called: Surfboard SB3100 Cable Modem. I am trying to plan ahead as to what i am going to do in order to get wireless internet. All i know is that i need to buy a router or one of those mac airbases but i dont know which or how to set it up. Can someone tell me what to buy and how i should do it??? I tried looking for a post similar to this but when i tried reading them i couldnt understand what people were saying since i have no idea how wireless internet works. please help!!!
