Wifi during install but not after

Hardware Support
1

Hi there,

I've installed Zorin 18 Pro on my pretty new LG Gram and Wifi was working/connecting during installation but after installation on first boot there was no wifi.

I was required to plugin USB LAN adapter, install the latest Zorin updates, and reboot, to get Wifi supported.
Here's my laptop spec:

You can try to go back to kernel 6.14. At grub menu select "Advanced options for Zorin" and select kernel 6.14 to boot from and test if WLAN works then.

If the grub menu isn't displayed at boot press continuosly esc key (or left shift key) during boot to show it.

So, Your Wifi works now, yes?

If not, some Questions:

  • Are Secure Boot and Fast Boot in BIOS disabled?
  • If Windows is still installed: Is Fast Start-Up in Windows disabled?
  • Does Your System run in Wayland or X11? You can check that with the Terminal Command echo $XDG_SESSION_TYPE
  • Did You take a Look in the ''Additional Drivers'' Tab in Software & Updates if there is a Driver for Your Wifi offered?
  • Could You post the Output of sudo lshw -C network and rfkill list please?

Yes, it is working now after connecting with LAN cable and installing latest updates.

  • secure boot is disabled
  • Windows is installed, can't check right now if faststart is enabled
  • I'm running Wayland
  • I assume after I connected the LAN cable and installed latest drivers, it did install new Wifi driver. I didn't check it at the time though.
$ sudo lshw -C network

It seems that it has. From the Output, I can see that Driver and Firmware is loaded.

Right, the output is from after I upgraded using LAN cable. WLAN worked after that.
Is it expected with this wifi/laptop to have WLAN supported during installation but not on first boot after installation and this can only be fixed with an upgrade using LAN?
I think this could be an issue for first-Linux users.

I don't know ... when You have it installed during Installation, it should work directly ... maybe with the Update came some addtitional Stuff or there was something wrong during the Installation Process what the Update has fixed. Or maybe only the Ghost in the Machine, hahaha!
