FIVESPOT connected via wifi to non-wifi enabled computer. What do I need?

I have a fivespot.


I own several devices and would like to be able to use them simultaneously.  I cannot do this right now because the fivespot has to be plugged in via USB to get internet on my desktop computer.  My desktop is not wifi enabled.


What do I need?


Best Buy said I needed Belkin - N600 Dual-Band Wireless-N+ USB Adapter and it did not work.  I also bought Medialink - Wireless N USB Adapter - and it did not work.  I am thoroughly confused.  Can someone please help me?
