so I have come across this problem where after I reset and reinstalled my OS on my laptop, the WiFi button has been greyed out or gets greyed out when clicking it, and the airplane mode button has been greyed out and is enabled.
What I tried:
- Install the provided drivers by DELL.
- Performing a full BIOS update.
- Contacting DELL(This didn't work because I was out of warranty and I do not want to pay anything). -Installing Windows 10 on an SSD.
- Disabling the airplane mode switch.
- Updating Windows 10. o) Resetting BIOS.
None of the above options worked for me.
My Observation:
One strange thing I noticed was with ubuntu, both Bluetooth and WiFi where working perfectly without any issues, so my guess is DELL has some driver that connects the hardware and OS properly due to their oddly designed BIOS, so the normal intel drivers wont do.
EDIT
I noticed something new, so when installing windows again but this time 8.1, the WIFI was working, but after a restart, I was back to square 1. I have windows 10 right now.
