Stupid question alert: I am starting back school in a few days, and I will need to bring my iPad with me to our family business so I can work on stuff when we aren't busy. The only thing we have now is a modem with an Ethernet cable attached to it plus a cable attached to each computer. Do all I need to purchase now is a wireless router to get Wi-Fi up and running? For some reason we have never had a wireless router, and I'm not sure all how it works, so I want to make sure I get the correct stuff needed for Wi-Fi since my iPad is Wi-Fi only. Any help on setting it up and how to get Wi-Fi going will be great. Also, any tips on which router to buy? Thanks!
