i use arduino mega 2560 r3 and Arduino Wi-Fi Shield (antenna connector) i have interface cable and antenna
i test my wifi shield with example > scan networks when i open serial monitor it away print "WiFi shield not present"
i try to fix it. i change version ide 1.0.5 to 1.0.2 but it not work
please help me
Which wifi shield do you have? A link to that hardware would help.

this is my wifi shield
Insure the shield pins are connected completely into the Arduino sockets, and the shield's ICSP socket is connected to the ICSP pins on the Arduino.
Also insure there is no SD card in the slot.
You do have a Mega R3, correct? The wifi shield does not have "extra pins"?

yep all pins are connected completely into the Arduino sockets
no sd card in slot
i have mega r3 and i guess wifi shield not have a extra pins
i think my shield is broken so i connect led circuit to my shield it work but it cant scan network and mac address is 0:0:0:0:0:0
It appears the SPI bus has failed, or the wifi ICs have failed.
thanks SurferTim
now i try to fix this problem T T
Check the ICs carefully for solder bridges on the wifi shield.
Also check there is power on the shield's IOREF pin. I have a Mega 2560 R2 and the wifi shield has two extra pins that hang over on each side of the Mega. That setup requires a jumper from the 5v pin to the IOREF pin on the shield to get the shield to work. Without that jumper, it gave me the same response you are getting.
i try it but still not work
now i think my board is broken i will send it to my shop to change it
thank for help me mr surfertim
