My 5G network disappeared on my MacBook Air, while my iPhone X and other devices find the 5G network without any issues. This happened after a software update. I have rebooted both the modem and router, checked configurations with my router, forgot the network and reconfigured it, etc. Nothing suggested online has worked. Can Apple please check the diagnostics and programming with the latest software update that doesn't show the 5G network?
