I got a wifi only iPad for my mom for mothers day because I thought there was an open wifi accessible from her house (it works for laptops). But nothing shows up as available on the wifi network list on her iPad. I wanted to know what's the cheapest way for her to get a usable wifi at home. I don't think she would be a very heavy data user. Would something from clear or some type of my-fi be the best bet? Or a router thing?
