Wifi works with Ubuntu, Manjaro but not with Mint 19.3

[Perikk]

I bought a Dell Laptop. It's
After i removed windows I installed Mint 19.3 (cinammon)
Wifi not present.
I had a usb stick with Manjaro 19.0.2 on it so i tried it. Wifi worked.
I made a stick with Ubuntu 19.10. Wifi worked.
I tend to conclude that it's the 5.3 kernel that is at fault.
Any ideas?

Use the Mint Update Manager, View/Linux kernel menu to install an older 5.3 kernel, then reboot and use Grub menu advanced options to boot into the older kernel. Ubuntu did some cherry picked updates for Intel wifi drivers in 5.3.0-40 that didn't work

[Perikk]

I 'll do it and I 'll post the results.
Thanks for taking the time

[Perikk]

No luck.
I tried 5.3.0-28 -26 -23 and 5.0.0-32
Is there something more i should do? I just booted (after choosing each one in grub) and checked to see if wifi is active.

[JeremyB]

I would install just normal Mint 19 with updates and that should work

[Perikk]

I ll try that as well.

So, i tired it with 19, 19.1 and 19.2
I couldn't even boot for some reason. This has never happened to me before.
Instead of booting with the older versions it gives me a tty prompt.
This happens even if i boot in compatibility mode.
With 19.3 it boots just fine. Just no wifi.
I guess i ll go with manjaro for the moment until kernel 5.4 is available.

You can try to install backported driver. viewtopic.php?p=1762336#p1762336

Reboot your PC after installation. You must disable secureboot from BIOS/EFI settings.
