Try a known working wifi card and wifi/camera cable. If it is not this (and it is not a software issue), it will be a logic board issue. Check the components in front of the wifi cable for any which have burnt (inductors, pins on connector, capacitors, etc) and check L3404 on the back of the board, using a schematic and board view, which supplies 5V for wifi to the card, which can commonly burn and stop the voltage passing through.
