WWAN card stopped working after Windows 10 update

I have Dell 6330 with Windows 10. In the laptop I have a HSDPA-modem (DW5804) that worked until Windows 10 was updated with aniversary update. After that it returns error 651. Anyone experienced the same?

Hi ILPOSTINO_NORWAY,

Kindly check if the ethernet cable works?

Run the diagnostics by pressing F12 during startup and let me know the results

Also update the WWAN driver from the dell support website.

Also, please click my DELL-username and write me a private message with the service tag and your Name for case records.

Let us know if you have any other queries.

Both ethered / cabled and wireless network works fine. All the tests passed and the latest driver is installed.
