Impossible to resinatll

Good day,

I bought the following product : https://sixfab.com/product/raspberry-pi-base-hat-3g-4g-lte-minipcie-cards/
and I succesfully installed this https://docs.sixfab.com/docs/qmi-interface-with-base-hat

I would like to add a PiJuice board, and as I installed Buster Little, I reinstalled my Rasperry with Buster Desktop.

Since, I can install the sixfab software, but I never can be connected. I reinstalled 4 times, and for the fift time I reinstalled the Buster Little, even even if the installation completed succesfully, I never can be connected.

i really sorry, but I do not have the Raspberry with me, but the error was due dhcp

Note, when yesterday, I installed the kernel

sudo apt-get install raspberrypi-kernel-headers

the version was

ls /usr/src

5…4.51

while previously, the version was

4.19.97

Do see any reason of a DHCP issue with the version 5.4.51?

Thanks
