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?

My hardware:

  • Ubuntu 16.04
  • Dell laptop

Update:

$ lspci -knn | grep Net -A3
02:00.0 Network controller [0280]: 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?

  • Could you post the full error message you got? – Grayson Kent Jun 20 '17 at 12:42
  • Disable Secure Boot. – Pilot6 Jun 20 '17 at 13:01
  • @Pilot6 hm, It was updated (UEFI) during last system update, before problems with wifi. And it can be a reason. But I can't deactivate it. After deactivation, it can't find device for loading. Should I reinstall the system? – demon101 Jun 20 '17 at 13:49
  • Secure Boot is disabled in the computer BIOS. You don't disable UEFI boot, but disable only Secure Boot. – Pilot6 Jun 21 '17 at 8:19
  • @Pilot6, with disabled Secure Boot nothing changed – demon101 Jun 21 '17 at 10:07

To purge the 'Additional Drivers' for wireless, please open a terminal and do:

sudo apt-get purge bcmwl-kernel-source

Reboot.

  • bcmwl-kernel-source not installed and can't be deleted – demon101 Jun 20 '17 at 13:08
  • Let's take a look at your exact wireless device; from the terminal: lspci -nnk | grep 0280 -A3 – chili555 Jun 20 '17 at 15:06

  • Driver works before, and stopped working, I think, this question is not a duplicate – demon101 Jun 21 '17 at 16:53
  • Please let us see: modinfo iwlwifi | grep 24FD and also: rfkill list all – chili555 Jun 22 '17 at 12:35
