Hello Alan!
First of all we must exclude a software issue. First, try to boot your Mac into the Safe Mode (press and hold the shift key immediately after pressing the power button to turn on your Mac).
If the issue persists, try to load your system from the external drive with known good system. Or, reinstall the system, using the newest available software your system supports.
If the issue persists, it’s related to the hardware part. The device doesn’t have detachable AirPort card like the MacBook Pro’s. The WiFi module is soldered to the logic board. So, in most cases the logic board should be replaced, but maybe you’ll find a good service center which will fix this logic board for reasonable price.
