boot from iso can't find wifi device

[geop]

Downloaded sparky rolling xfce version iso from sourceforge, and did check sha256. On iso boot, no wifi. Icon popup says "No network devices available".

Running dmesg -k, I found this:

[   10.853172] mt7921e 0000:01:00.0: enabling device (0000 -> 0002)
[   10.853413] mt7921e 0000:01:00.0: firmware: failed to load mediatek/WIFI_RAM_CODE_MT7922_1.bin (-2)
[   10.853423] mt7921e 0000:01:00.0: firmware: failed to load mediatek/WIFI_RAM_CODE_MT7922_1.bin (-2)

[   10.853435] mt7921e 0000:01:00.0: Direct firmware load for mediatek/WIFI_RAM_CODE_MT7922_1.bin failed with error -2

The last four lines of that are then repeated ten times, which is then followed by this:

[   11.725202] mt7921e 0000:01:00.0: hardware init failed

My system:

Framework-16
Processors: 16 × AMD Ryzen 7 7840HS w/ Radeon 780M Graphics
Memory: 32 GiB of RAM (30.7 GiB usable)
Graphics Processor: AMD Radeon 780M Graphics
Manufacturer: Framework
Product Name: Laptop 16 (AMD Ryzen 7040 Series)
System Version: A7

The laptop is currently running KDE Linux and KaOS with no wifi issues. Sparky was going to be my fun, experimental, distro.

Any suggestions?

Try to enable it manually:

Code Select Expand

systemctl start NetworkManager

Many thanks for the suggestion, but I've now tried that both without and with sudo, and in each case, it returned immediately to the terminal prompt with no output. The network icon popup still says "No network devices available".

I saw nothing in journalctl either.

Sorry I didn't reply more quickly, but I didn't see your reply until now because I failed to notice I had to explicitly request alerts. Fixed now.

OP here. I decided to install the latest weekly Debian-testing to see if the same problem occurred.

The installer, which is a netinst type and so needs a network, did NOT find my wifi device, but did give me a list of devices to install drivers for. I picked the mt7921e, the one mentioned in the Sparky error message, and the installer was then happy, and I was able to connect to wifi and continue the install.

(Once I booted to Debian-testing and logged-in, I just got a black screen, but that's a problem for a different forum. Since this was just supposed to be a fun side-experiment, I may just bail on the whole thing ... :-(  )

OP here once again. No resolution on the Sparky wifi issue, but Debian-testing is now working. I went back to the login screen and noted that it was set to XFCE  under Wayland, which I didn't even know was a thing yet. I switched it to plain vanilla XFCE and all is good.
