Yes, I am fairly new to Linux. Long story short, I have the XPS13 dev. Went from 18.04 LTS to 19.04 and all working. THen upgraded to 19.10 last week and wireless stopped working. I have the Killer 1435.

I tried stuff from these sites with multiple reboots and it suddenly started working. Unfortunately I was so frustrated (and stupid) I did not log what I did to get it working.

Killer Wireless 1650 on Ubuntu 18.04 doesn't work

I did an update yesterday (sudo apt update && sudo apt full-upgrade -y) and after a reboot, wireless network stopped working. I have a LAN adapter and using it now.

If I go to SOFTWARE & UPDATES | ADDITIONAL DRIVERS, I see "Intel Corporation: Unknown: THis device is not working". There are three options. -Using iwlwifi driver backport in DKMS format for backport-iwlwifi-dkms (Open SOurce) *This is grayed out and I can not choose it to even test -Continue using a manaully installed driver *This I can click, but after reboot, it is unchecked. -Do not use this device *This is always selected.

Any help would be GREATLY appreciated.

  • Please edit your question to show the result of these terminal commands: sudo dkms status and also: sudo modprobe iwlwifi && dmesg | grep iwl Welcome to Ask Ubuntu. – chili555 Oct 23 '19 at 14:08
  • I have the same problem.

    sudo dkms status backport-iwlwifi, 8042, 5.3.0-19-generic, x86_64: installed

    sudo modprobe iwlwifi && dmesg | grep iwl

I was in the same situation, and i saw that despite the successfull upgrade to 19.10, the kernel was still on 4.15 !

So i just made :

sudo apt-get install --reinstall linux-generic

And boom ! It worked !
