Wifi module for arduino shield Recently I bought a B006RATC2E wireless shield for my Arduino One, but didn't notice that I had to buy a wifi module as well to let it work (bad surprise as the shield already cost me $30 + travel expenses to CR). Could someone be so kind to suggest me some compatible wifi modules for the shield?

I'm kind of newbie in this and when I search specs for Adafruit and XBee modules, the documentation is not explicit about the compatibility with Arduino shields, so I'm stuck.

I don't want to buy components that would't work together (my budget is limited). Is XBee XB24 a good module for the shield? Any other alternative?

Thanks in advance for any help!
Wireless doesn't necessarily mean it's WiFi.
You should get an XBee module that explicitly states that it's a WiFi module.

For a cheaper alternative you can check ESP8266 WiFi modules, which you can get for $5.
