I had successfully installed and tested the SIXfab LET module with the EC25-E, and I can get an IP address and I’m able to ping any internet IP.
However, after a few minutes, the wwan0 interface loses the IP address and disconnects, and by checking the status of the interface with ifconfig, it shows me this
wwan0: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500
unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 1000 (UNSPEC)
uame -r
4.19.58-v7+, I’m using a Raspberry Pi 3B and I’m not able to upgrade the Os, as the QMI will not work on newer kernels.
BTW, I’m using this in combination with a LoRA Hat
lsusb -t

Any recommendation to fix this issue?
Thanks
