FEZ Spider & WiFi-Ethernet Bridge

i’m beginer in hardware programming and i’d like to test&buy FEZ Spider Starter Kit.
But i need wifi option.
So, may i use WiFi-Ethernet Bridge (http://www.ghielectronics.com/catalog/product/263) with FEZ Spider or i have to buy only WiFi RS21 Module (http://www.ghielectronics.com/catalog/product/282)?

Thanks in advance.

Both will work just fine. It is up to you. The module will give you a lot more options though, like searching for networks through code.
