RB922UAGS-5HPacD and ME909s-120 works fine - V6.37rc32 / firmware 3.34 - 11.617.01.00.00 however RB953GW-5Hnt-RP board and ME909s-120 not!! - V6.37rc32 / firmware 3.34 - 11.617.01.00.00 - > NO lte1 Interface! /system routerboard settings set init-delay=5 -> does not fix that issue. I double checked ...

seems this workaround works with RB922UAGS-5HPacD but not with RB953GW-5Hnt-RP boards.

Greetings, Andreas

Same issue with HUAWEI ME909s-120 11.617.01.00.00 and RB922UAGS-5HPacD, RB953GW-5Hnt-RP boards, LTE modem not recognized (direct-ip).
I think it is time to get a fix for that, since a long time this is an open case.
