I got new laptop and activated additional drivers for some of devices (video, cpu firmware).
But after activation of custom drivers for the wifi adapter, I get an error. And now, no wifi devices appear the in connections manager (no internet) and the wifi card is not listed on the additional drivers settings page.
After, I get the same problem for Bluetooth. It was gone from the additional drivers settings page, but the Bluetooth device is still working.
How I can purge additional drivers settings?
- Ubuntu 16.04
- Dell laptop
$ lspci -knn | grep Net -A3 02:00.0 Network controller : Intel Corporation Device [8086:24fd] (rev 78) Subsystem: Intel Corporation Device [8086:0050]
I have deactivated Secure Boot, nothing changed
UPDATE: Problem NOT in drivers. It works before. Dell laptop came with all drivers The problem in Additional Drivers manager. After some manipulations it fails with error. Now, I tried to change driver for device with name oem-bluez-autoenable. After error, this device was gone from list, like it was before for wifi

Is it possible to fix it?
