Wifi Card not installed, boot up issues too.
I believe I have the same issue as the post on top however it wasn't really well iterated, also I would like to fix it myself instead of giving free money to others for something I can learn.
Anyways, here's the issue description:
MacBook hung and shut down.
From then on, it would hang during boot and usually stops at PCI Configuration phase of boot.
Sometimes, it can't even get to the efi boot loader (aka white screen)
When it does boot, wifi card will have two possible issues.
Detected but unable to search for any networks,
Undetected and will state Wi-Fi: No hardware installed
Is there a method to diagnose the exact cause of the issue? Or if someone can confirm, what is the issue?
Wifi card died, or PCI, or motherboard.
Is this a good question?
