Comment 2 for bug 2039592

I had been helping this user on Ubuntu Forums: https://ubuntuforums.org/showthread.php?t=2491572

"English" is not this user's primary language, so let me help him explain this here.

This worked for him in 20.04. It is not working since he upgraded to 22.04.

For some unknown reason, lshw -C Network is not producing expected results on that device, so not a lot of human-friendly readable information is being shown.

His system sees his WWAN card as you can see in his attached WifiSyslog.txt:
жов 17 19:36:29 denis-HP-EliteBook-840-G1 kernel: usb 2-6: new high-speed USB device number 4 using xhci_hcd
жов 17 19:36:29 denis-HP-EliteBook-840-G1 kernel: usb 2-6: New USB device found, idVendor=03f0, idProduct=521d, bcdDevice= 0.01

жов 17 19:36:29 denis-HP-EliteBook-840-G1 kernel: usb 2-6: Manufacturer: Hewlett-Packard

What isn't showing up there in that log, is anything about a driver being attached to that device.

In the attached RfKill.txt, that device does not even show up in the list.

But his syslogs say this:
Code:13:26:44 NetworkManager: <info> [1696760804.3166] audit: op="radio-control" arg="wwan-enabledn" pid=2374 uid=1000 result="success"
13:26:44 NetworkManager: <info> [1696760804.3166] audit: op="radio-control" arg="wwan-enabledn" pid=2374 uid=1000 result="success"
13:26:44 NetworkManager: <info> [1696760804.3159] manager: rfkill: WWAN hardware radio set enabled
12:37:51 NetworkManager: <info> [1696757871.8350] manager: rfkill: WWAN enabled by radio killswitch; disabled by state file
12:37:51 NetworkManager: <info> [1696757871.8190] Loaded device plugin: NMWwanFactory (/usr/lib/x86_64-linux-gnu/NetworkManager/1.36.6/libnm-device-plugin-wwan.so)
12:37:51 NetworkManager: <info> [1696757871.8124] manager[0x55e016153040]: rfkill: WWAN hardware radio set disabled

So rfkill is seeing it and addressing it, the NNWwanFactory module is being loaded, but the device is not being left as enabled...

That is what I know about it.

Is anyone going to triage this soon? It has been 5 days now... When I refer a user to file a bug report, it's because I have faith that when I do, it's the correct thing to do for the improvement of Ubuntu, that something is wrong, it is not working as expected, that can possibly be corrected.
