Replace factory Intel WiFi module with a macOS compatible one. Make sure that the card is of M.2 form factor. I replaced it with the BCM94360CS2 card. This works out of the box without additional kexts and has been stable for me thus far.
**If your laptop did not come with WWAN, you can purchase additional antennas to add to your laptop. This is useful when using WiFi/Bluetooth cards that have 3 antennas.**
However, there exists other alternatives with better WiFi and Bluetooth standards, but additional kexts are required. See [`dortania/Wireless-Buyers-Guide`](https://wifi.dortania.ml/).
