Cannot connect to cellular – Connect script failed

[Christos Mourouzis]

Hello,

I am trying to configure cellular connection on a Multitech Conduit IP67 Base Station – mLinux version. I have tried two sim cards. I inserted the sim card with sim contacts facing down and its cut corner to be up-left (while facing the sim port) – this is the only way that it clicks anyway.

I set correctly the APN. When I call pppd call gsm or pppd call leu1 with their default configurations I don’t have a successful connection. Instead I get the following in the log messages (/var/log/messages):

Am I missing something? The sim card for the aforementioned example does not require authentication.

Also, I would like some instructions on how to configure PAP Authentication for another sim card that I have because I can’t find any information in the datasheet or the website.

Thank you very much!

Hello Christos,

For help with this you could open a support portal case at https://support.multitech.com. They can provide better support than the forums.

Hello Jeff,

Thanks for the reply. I opened a case on the multitech support as you suggested. I managed to have some progress on my issue. Maybe someone could help with the following:

I changed the location of the gateway and I managed to get connected to the APN but I have a modem hangup (SIGHUP).

I need the instructions for authenticating my sim card (Simfony) because it requires a username and a password.

In the log file I get:

Even if edit /etc/ppp/pap-secrets or /etc/ppp/chap-secrets file with the correct username and password I can’t manage to get a successful connection.

Can someone please provide me the instructions for having a ppp connection with authentication?

Thank you very much!
