I’m using the raspberry Pi 3G-4G/LTE Base Shield V2 with a Quectel EC25 Mini PCIe 4G/LTE Module.
I follow the procedure to activate the PPP0 channel and it goes fine but I can not navigate on internet ( it seems the USB communication line is frozen). The only way the base shield start to work well ( I can navigate on internet) is when I physically disconnect and reconnect the USB connector that connect Raspberry to the Shield ( whitout to power off the power ).
Please I need a procedure or any suggestion to activate the PPP0 channel and it continues to be active even if i power off and then power on the HW.
Thanks in advance
