if zou want to do yourselves and loved ones a favour, zou could stay on the eterhnet cable, until better options come our way.

For now, that's how it's going to be - cable + Ethernet connection

Then, hope to find the right solution.

If anyway as the right solution to re-establish the Wi-Fi connection, please inform.

one possible solution for wifi-issues can be to get an ethernet cable;
works most of the times, sometimes it needs addtional gear (or software, packages, patientce).

Hello...
The sound issue is solved.
The Wi-Fi connection issue is still there.
I applied all the proposed solutions by IA, but they are not working.
Can someone advise, please ?
Thank you.

Hello

The issue already existed, but somehow I could make things work again,
by first connecting to a cable and then trying to run some corrections.
Then I got wi-fi again (I don't know how) and lost it now when using the system.
Decided to install again the system (not thru refracta) and the error message came again.
That's why I'm trying to fix it.
Thank you.

Did this error occur during installation, or sometime afterwards? That is, did installation complete and now the installed system has no wifi/sound ?
Also, which installer did you use (desktop-live, netinstall, ... ?)

On the excalibur installer iso, sof-tgl.ri is supplied by firmware-sof-signed_2025.01-1_all.deb
It could be helpful to check the shasum of the iso.

If this error is keeping you from installing, it's recommended to use (wired) ethernet, if it's available.
