I have a project where I am sending data to the internet. I am using the Mega 2560 and the Arduino WIFI shield. However, I will put this project in a box and the internet connection maybe weak. I was looking into a shield with strong signals and came across this link. Recommendations For You - DealeXtreme
The wifi I got is from this link http://arduino.cc/en/Main/ArduinoWiFiShield
I know they do different things and are best suited for they own application and comparing would be hard. I am just trying to find out for my application, where I am merely sending data to the internet and receiving data from the internet on a txt file on a server. Which device would be better considering I maybe 100 to 300 feet away from a modem or router? What ratings do I look for when determining these performance characteristics? Thanks.
