Current firmware for EG25-GC

I have a GPD WinMax2 with a Quectel EG25-GC LTE modem. I have issues connecting to the internet. When i connect and ping 8.8.8.8 I get the Error “General Failure” back.
I already updated the drivers to the Version 20.0.65.3

This is my card:

ATI1 - Quectel
EG25
Revision: EG25GGCR07A02M1G

Maybe a firmware upgrade can help? Please, can you send me the latest firmware for my LTE model? Thanks.
