Can't connect to Wi Fi using the Live version of Tumbleweed

Trying Tumbleweed last version, Live ISO
openSUSE-Tumbleweed-KDE-Live-x86_64-Snapshot20250604-Media

When trying to add my WiFi, Wallet is playing with me

IF I choose the more secure wallet method, it ask to choose a key (none there)

If I choose the other method. Wallet crash or I go into some loop, I enter a password, it work, try to add my WiFi network connection and it doesn’t connect.

Am I missing something ?

For now I will follow what the forum suggested in a different thread :

“If you do not want to use a (this) password manager at all you can disable it in KDE system settings. Enter “system settings” in the search bar of KDE start menu, go to Personalization - Account Details - uncheck “Enable the KDE wallet subsystem”.”

My bet is that KDE Wallet got broken specifically in version 20250604. Everything you’re doing in live ISO won’t be saved to disk normally. So I think it’s safe not to use it until you’re going to install the system. Once you got it installed you can try my fix described here.

Actually it will. The only thing a Live USB cannot do is upgrading the kernel.

I did some tests in VM. I tried writing live ISO to a virtual 8 GB usb drive using KDE’s ISO Image Writer and it did worked. Files and settings persisted even after rebooting. Before when I was writing images using Rufus on Windows files would disappear after rebooting. Thank you for correcting me.

SO the way / tool you are using change the result ?

I often use Balena Etcher on Linux…

Bad ?

I started using Ventoy a bit but do not know the Pro and Cons of Ventoy

Ventoy is not recommended nor supported by openSUSE. Ventoy adds boot parameters to openSUSE images, which renders the system broken. Additionally there where recently security issues discovered with Ventoy (undocumented blobs).
When you open an openSUSE bugreport and it gets known that you used Ventoy for installation, the bugreport will be closed as invalid due to the above reasons.

You can use it, but do not expect any support from the openSUSE maintainers when issues due to this tool occur.

Seems that way. Rufus is blindly writing ISO to USB drive, KDE ISO Image Writer is seemingly more clever about it. One I had with Rufus ended up being read only. One KDE Image Writer made was both read and write capable.

Only one way to do it right.

Copy a pure unmodified binary copy to the USB device (not a partition on the device) No install helpers!!! I use the cp command. It works fine dd is also an option

Always dd here. And I even make sure there is “no remains” on the USB device by dd’ing /dev/zero to the 1st 50 MB of it, only then dd’ing the ISO to it.
