Arduino wifi sniffer Answered

Is it possible to connect an Arduino Ethernet Shield R3 (official) to a wifi router then connect to a different router though the first router? I want to do this so I can make a robot that when it finds a known network it connects to it then dumps the data from the sd to an online server. Can anyone help me with this? I have an Arduino Uno R3 (official) and an Arduino Mega 2568 (clone).


I want to use the router as I already have the Ethernet shield and arduino, and I can't get a wifi shield from sparkfun.

The shields are sold elsewhere.

You will need to look into converting the router to an access point. It will take some work to flash it with the new firmware so it will work how you need it to.
