Dear Garytan98 -
The term WiFi refers to a wireless protocol used to connect various wireless devices (PCs, cameras, cell phones, etc.) to another device or the internet. Thus you cannot "store" WiFi but I believe you want to store content (music, videos, files, etc.) from another device or the Internet using WiFi. The Seagate product you referenced is basically a storage device (like a hard drive) that connects wirelessly using its own WiFi network (rather than the Internet) to another device to store content without using the internet. You can of course download content from the Internet on any device and save it on the Seagate wireless plus.
Having said all this I believe that the Seagate Wireless Plus is the device that you have described. You may want to work on a better understanding of WiFi and the Internet, the proper nomenclature and the theory of operation.
Good luck with you project.
