Problem
Keine Internetverbindung, ungültiger APN verwendet oder die LTE-Schnittstelle empfängt eine falsche IP-Adresse.
Lösung
Standardmässig verwenden MBIM-Modems den vom Netzwerk bereitgestellten APN und ignorieren den manuell eingestellten. Bei einigen SIM-Karten kann das Modem einen unerwarteten APN aus dem Netzwerk empfangen. Um dies zu beheben, verwende use-network-apn=no zum APN-Profil.
/interface lte apn add apn=internet use-network-apn=no /interface lte set lte1 apn-profiles=internet
Problem
LtAP log messages indicate, that the SIM card is not inserted:
00:05:35 lte,async lte1: sent AT+CPIN?
00:05:35 lte,async lte1: rcvd +CME ERROR: SIM not inserted
Solution
The modem does not see any SIM cards inserted:
+CME ERROR: SIM not inserted
Please check if you are using the correct SIM slot. For the modem inserted in the bottom mini-pcie slot (this is the slot where modem that comes pre-installed in an LtAP lte kit is located) you need to use either sim slot 2 or sim slot 3.
The used sim slot needs to be selected in RouterOS.
CLI command to select the sim slot:
/system routerboard modem set sim-slot=2
