XPS13 7390 wireless stopped working on 19.10 after update yesterday

Yes, I am fairly new to Linux, but I love it so far. 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.

Hi, welcome to the fora.

As a first and general experiment I always suggest a clean install of 19.10 using the LAN connection. After that apply all updates and reboot without LAN. Is there any change?
