I have ZBT WE-826 Router with Sierra Wireless MC7354 mPCI-e Modem.
The router sees the modem and shows me the parameters of modem such as signal strength, SIM-card IMSI and phone #, but I don't have internet on router. Router does not get IP-address from Verizon.
I read somewhere that I have to use kernel 4.5 and above. I have 18.06.0 v with 4.14.54 kernel.
Do I need to upgrade kernel? If "Yes", how to do this?
