Hi
I am looking for the same answer as Tonyzhang.
Which Wi-Fi shield is the best one for arduino (or other arduino "compaible" controller boards)
My defintion of best would be :
the one which have the more possibilities (supported protocols b/g/n..., supported encryption)
the fastest one (throughput speed, limited of course by the Arduino communication speed itself)
and maybe some other parameters i may have forgotten or not familiar with
Thanks
