Hello,
I have fios, but haven't downloaded wifi from it. My computer died and I was just going to get an IPad for now. Can I install the wi-fi from FIOS just on the IPAD?
You don't download wifi, it's hardware, usually in the Router.
You can use WiFi on any device, don't need a computer AND another device. You can hook up WiFi on an Easy Bake Oven WiFi edition if you like without a PC, just need a wifi router of some sort. When they installed FIOS you did not get any documentation or have the tech show you how stuff works?
