No Wifi on OpenSuse Leap 16 KDE / Password not safed

Hello everyone,

I’m a Mint user since a few months (EndOf10) and quite happy with it. I’m still an absolute Linux beginner though.

Reading a lot about OpenSuse, I decided to give Leap 16 a shot. I installed that one on an external SSD so that I can still keep my Mint system untouched.

I solved the black screen problem with nomodeset. But now I got another problem but I still don’t want to give up:

I can not connect to my Wifi. Any time, I open the Wifi settings, the CPU fan is going crazy and nothing happens for about 10 to 20 seconds.
After entering the WPA2 personal password it still wouldn’t connect. Again, after a lot of time at the highest possible RPMs for the CPU cooler, it says that it can’t connect and will be disabled.

I found this threat:

I have somehow the same problem but couldn’t solve it by disabling the password safe.

I also tried to reboot every now and then after changing the settings back and forth. Nothing helped!

My system is:
AMD 3900X
32 GiB RAM
NVIDIA GTX 3060
ASUS Wifi Stick

Leap 16, KDE, installed the offline version on an external drive (128 GiB) used the partition presets, only changed the swap size to 34 GiB (I read that it should have 2 GiB more then RAM).

Any more information needed?

Can anyone help me?

Thank you!

Philipp

USB-Stick?

Sorry, I wanted to say ASUS Wi-Fi adapter.

I don’t know the product name. It is a recent adapter. It works perfectly in Mint.

The Name is not important, only the ID is important.
So post:

Do you mean this:

Bus (…) ID 0b05 : 184c ASUSTek Computer, Inc. 802.11ac NIC

Tank you

Is kernel-firmware-realtek installed?

Sorry, how can I post the whole list without internet connection?

Besides I also tried nmtui. It also says that connection failed. Wi-Fi couldn’t be found.

You can get an Internet connection by sharing your phone connection by tethering.
If you don’t know how to do this, you can easily find a guide on the Internet.

Sorry, I can’t - it’s an old desktop PC, no Bluetooth, Wi-Fi doesn’t work and I have no cable.

Maybe you can use an USB-Stick and anther PC for posting here?

Ok, I’ll might try…

What can one see on the complete list?

I mean, I think the problem is the password manager. It keeps asking about die Wi-Fi PW repeatedly. When I close the PW manager, while starting Wi-Fi settings it says that it must also start the PW manager again.

Also the hardware was recognized by the system and all Wi-Fi networks around here are in the connectivity-list. It just doesn’t want to connect somehow.

I double checked the PW several times - it’s correct.

I also tried to connect to a Wi-Fi hotspot on my phone. That didn’t work eighter.

My Wi-Fi stick works flawlessly in Mint 22.2, Zorin 18 and Ubuntu 24.04 (the latter two also installed on an external SSD for trial) out of the box - I tried all of them. Maybe the Debian based distros can handle the thing better. It’s also brand new - I bought it for Mint as my trusted old adapter didn’t work with any Debian-based distro.

I probably will stick to Mint for the moment since this system works for me (never change a running system) and my wife uses Zorin which is quite similar.

Thank you for the replies!

Have you installed kernel-firmware-realtek ?

Kernel-firmeware-realtek:

I don’t know. Are additional steps necessary after installing the system for that?
How (without internet connection)?

Use rpm to see ift it is installed and you get:

stephan@linux64:~> rpm -qa kernel-firmware-realtek
kernel-firmware-realtek-20251217-lp160.3.1.noarch
stephan@linux64:~> 

Yes, it is installed, but an older version:

kernel-firmware-realtek-20250717-160000.1.2.noarch

I just found this in the German forum:

It’s about the black screen problem and nomodeset.

I also installed Leap 16 with nomodeset (have still no graphics driver while no internet - that’s going to be the next problem to solve).

Would it be a good idea to deacitvate nomodeset first

update-bootloader --del nomodeset

and

update-bootloader

Or isn’t that possible without internet?

Without nomodeset, you will have a black screen. So what is your goal?
Btw, this command is wrong, see some comments further. It needs to be --del-option

Hm, I read that nomodeset is only for the installation process. It will seriously slow down the system when keeping the setup.

But it makes sense to install the NVIDIA driver first and then get rid of nomodeset.
I just thought that this might affect the Wi-Fi adapter, too.

But then no Internet, no NVIDIA driver…

You can only remove nomodeset, when you have the appropriate Nvidia drivers installed. Else: black screen without nomodeset.

First goal should be to get your wifi running. Installing the Nvidia drivers afterwards is a task of some seconds.

So if your adapter works perfectly in Mint, where is your problem posting the terminal output asked for by Sauerland?
