Description Alessandro Bono 2023-07-10 17:37:12 UTC 
Hello, I was using Fedora 37 with kernel `6.1.13-200.fc37` and everything was fine. After updating to `6.3.8-100.fc37` my USB WiFi dongle stopped to work.

The device is `0ace:1215`: https://linux-hardware.org/?id=usb:0ace-1215 - It is a ZyDAS device. Switching to the previous kernel makes the device work again.

As you can see I have three kernel versions installed
```
$ ls /boot/config-*
/boot/config-6.1.13-100.fc36.x86_64 /boot/config-6.1.13-200.fc37.x86_64 /boot/config-6.3.8-100.fc37.x86_64
```

Furthermore, the problematic one doesn't have CONFIG_ZD1211RW set.
```
$ grep CONFIG_ZD1211RW /boot/config-*
/boot/config-6.1.13-100.fc36.x86_64:CONFIG_ZD1211RW=m
/boot/config-6.1.13-100.fc36.x86_64:# CONFIG_ZD1211RW_DEBUG is not set
/boot/config-6.1.13-200.fc37.x86_64:CONFIG_ZD1211RW=m
/boot/config-6.1.13-200.fc37.x86_64:# CONFIG_ZD1211RW_DEBUG is not set
```

I think it might be related to this commit https://gitlab.com/cki-project/kernel-ark/-/commit/5089d3b1b9b45575055be46a03dda13c62816584 - I don't understand if this has been done on purpose or if it is a overlook.

Reproducible: Always

Steps to Reproduce:
Boot the system with kernel `6.1.13-200`.
Actual Results:  
No WiFi panel is listed in GNOME Settings

Expected Results:  
WiFi panel should be present in GNOME Settings
Comment 1 Peter Robinson 2023-07-13 16:26:51 UTC 
Just to confirm whether it's definitely just the ZD1211RW  and not the USB_ZD1201 driver.
Comment 2 Alessandro Bono 2023-07-13 16:36:09 UTC 
The device is `0ace:1215` and according to https://linux-hardware.org/?id=usb:0ace-1215
it needs CONFIG_WLAN, CONFIG_WLAN_VENDOR_ZYDAS and CONFIG_ZD1211RW enabled. So yes, I
think it is just the ZD1211RW and not the USB_ZD1201.
