WWAN/LTE Card stopped working

[799]

Hello,

I have applied Updates to my Templates and also flashed Coreboot ony X230.

I haven't used my internal WWAN Card for a while as I was using WiFi.

The WWAN Card was working before (default template/Stock ROM) without a problem, now it doesn't.

I can pass the WWAN per sys-usb to my sys-net and I can see that it it present there (lsusb).

But I can't use Gnome Network Manager anymore to us it.

I have also tried to pass the whole PCI Controller which includes the WWAN Card as USB device to take sys-usb out of the equation, but I get the same result.

Do you have any idea where to start troubleshooting?

This might be a coreboot item. I noticed on the T420 (I think it was),
coreboot didn't support the WWAN slot.
