Many high-end motherboards come bundled with WiFi and Bluetooth, usually via an M.2 module. Unfortunately, most of those are only designed for Windows, and are not compatible with Linux. Since these WiFi/BT controllers are modular, they can be swapped out - but there is often quite a bit of work involved to access them, as they are often situated behind other components and thus require removal of heatsinks and shrouds. This service line item covers the additional labor time involved to disassemble the board, swap to a different module, and then reassemble.
Please note that the price of the alternative WiFi module is not included.
