I have a wAP R ac (arm). I have installed a SIM Card and can go to the internet. Now I use a special Service APN and will start a PPPoE session, but I cannot select the LTE Interface. What can I do to select the LTE Interface?
It’s a Fallback solution, if DSL is down, i can get the same static IP from the provider.
A PPPoE interface can only be attached to an L2 interface. The LTE modem cards come in two flavours, one can only emulate a serial port whilst the other one can emulate also an Ethernet port, and this option is preferred unless disabled using /port firmware set ignore-directip-modem=yes and a reboot.
So if your LTE modem only supports serial port emulation, you must use /interface ppp (and maybe you can get the proper IP address if you use the correct APN and user credentials); if your LTE modem supports Ethernet emulation, it will show up under /interface lte and it might be possible to attach /interface pppoe-client to it.
the Option /port firmware set ignore-directip-modem=yes have I also test, but with a ppp connection also don’t work. I think the modem was not realy work with USB?
