I am moving in a week.I have always used the cable company's modem for internet. Our old house we used Apple airport express and cable modem. In temporary condo now using their modem(no airport express). If I want wireless internet in new house what do I need to buy so not renting their stuff? Already have the AAP. Do I just need to buy a modem say from BB and use airport express to have the wireless once I set up ISP.
