Arduino Wifi Shield Hack with Ethernet Shield

Last week I really needed Arduino wifi shield to start a home automation project. But in fact wifi shield is too pricey. So I had an ethernet shield and a portable wifi modem like this. Mine is a little bit different but functionalities are the same. Make sure that yours has RJ45 ethernet output.

So, I realise that if I connect my wifi modem to internet and than with an ethernet cable connected to the shield ,I will have a wireless shield !
