Hello, I’m working with an EC25-AFXD Mini PCIe module plugged into a Mini PCIe to USB adapter board with a Verizon sim card going into a Rasberry Pi. About a month ago this setup was working perfectly and I was able to connect to the internet. More recently, this module no longer shows up as a network interface in Linux. I’ve included the output from ModemManger, NetworkManager, etc. Does anyone have an idea how to solve this? Thanks
