Version K phaser mainboards and above have a replaceable Wifi module. These Wifi chips can be replaced if they malfunction. This is much more economical than replacing the whole mainboard if just the Wifi fails.

Please keep in mind that this article only relates to Revision K and above mainboards.
If you need to replace a phaser mainboard (of any revision), please read this article.


Replacing the Module
Start by powering off the phaser by inserting the key into the slot in the back sensor. The phaser is off when all the lights have turned off.
Disassemble Phaser
Remove the nozzle with a screwdriver or the head of the hex driver by slotting in into the gap at the front of the phaser. Then use the hex driver to unscrew the 6 hex screws on the bottom of the phaser. Ensure that the hex driver is set to 9 and is set to the reverse direction. The top plastic enclosure should now easily pull away.
Replace the Wifi Module
Unscrew the 3 screws holding the Wifi module to the mainboard. (HT1007 1.5mm hex drive screwdriver)
Carefully replace the malfunctioning Wifi module with a replacement one from your spare parts.
Fasten the 3 screws to secure the Wifi module in place.
You can now reattach the top part of the enclosure using the electric hex driver.
