Ubuntu: Wlan function missing?

Moin, I have just replaced Windows with Ubuntu on my laptop, but in the network area I only see cable connections and VPN, there's no trace of a Wi-Fi function.

Unfortunately, none of the search results helped me and I don't know Ubuntu well enough.

What could be the reason, or what can I do to make it displayed?

Vmtl is simply missing the appropriate driver for the WLAN. It's better to check something like this beforehand, it happens very often.

Connect to the LAN and install updates.

It is best to check which WLAN card is installed via lsusb or lspci and look for it specifically. Is Vmtl in linux-firmware-nonfree or something.

I know the built-in WLAN card (Intel 8265), firmware downloaded and now I can't get any further.

Where and how did you download the firmware? I need a little more information to be able to help you…: /

https://www.intel.de/content/www/de/de/support/articles/000005511/wireless.html Here I downloaded the corresponding one (9th in the list). Then I looked in the readme from the download, there's a command for the terminal in it, but it doesn't work for me because the file can't be found. I guess I still have to drag this into a certain folder, but I'm still overwhelmed with where exactly…

Correct. Downloads are usually stored in ~ / Downloads /. But in the text there's

Linux drivers are part of the upstream Linux * kernel. They are through the normal channels, distributions or the
http://www.kernel.org/ available.

Therefore the way you want to go right now is the typical "Windows way", downloading an .exe somewhere and wanting to install it. Under Linux this usually works via the package management and that is what the text says here. Try it

sudo apt update; sudo apt install iwlwifi-modules

It's strange that Ubuntu doesn't include them. At least under Linux Mint (which comes from Ubuntu), this is preinstalled and a meta-package. Hopefully that's enough.

Is the laptop very, very new or very, very old?

I hope that wasn't too instructive now. Was meant to be friendly.

I will try it out later, thank you very much! The laptop is at least not very old, but neither is it the newest of the newest. ASUS G505, if I'm not mistaken.

With pleasure. I hope this is enough. Sometimes hardware is really stubborn.

Unfortunately it didn't work. I entered the command, which he also carried out, then I should restart, boot, but still have no Wi-Fi in the overview. I just entered it again in the terminal, at least it tells me that it is up to date: "backport-iwlwifi-dkms is already the newest version (8613-0ubuntu2)."

Great. It's really annoying. Then maybe try the package from Intel. To do this, you have to go to the Downloads folder first, I think. Usually everything is saved there.

cd ~ / Downloads

And then run the commands as suggested. No guarantee that this will work.

Otherwise just try Linux Mint or Gecko Linux.

Unfortunately he says the same to me: "backport-iwlwifi-dkms is already the newest version (8613-0ubuntu2)."

Then I don't really know what to do from afar.

What I would do next: Try Linux Mint or Gecko Linux in live mode and see if it works.

Update: I did it. I tried it again, then it worked, I have no idea what I did wrong before, I probably took a wrong turn somewhere earlier and the reboot did not work properly.

Very good. Yes, sometimes you really don't understand why something works or not.

But it works now and that is the main thing. 👍
