RUTC50 Modem issue since Update - Mobile 5GMM reject cause: N1 mode not allowed

Networking Solutions Issue
36

Hello,

I’ve also found this topic while searching for “URC Event: 5GMM reject cause => N1 mode not allowed”.

I have the issue on two RUTM30 devices for months now (see my topic here: RUTM30: cannot get IP connection (PAP authentication)).

In my case, the following does not fix the issue (I can’t get any data connection):

  • setting “Preferred network type” to “4G only” or “4G/3G auto”
  • using the modem firmware RG520NEBDCR03A06M4G

(I’m already in contact with the support, I’m not hijacking this thread, only adding myself to the list of impacted users)
