Question

Hi,

RUT240

FW R_00.01.11.3

Mobile overview keeps showing

Data connection "Disconnected"

Stat "Registered"

SIM card: Ready

What is the router doing in this mode?

What is this connection status even called?

What is the cause?

How can I tell the router that "Regeistered" but "Disconnected" is not a statisfactory status and automatically reconnect, looke for a new provider or do whatever elese is neccesary to get a data connection?

Currently I am doing the automatic modem reboot if the device can't ping google, but this seems like a bit of a hack.

Hello,

In this state, the router is Registered on to the operator but has no data connection. In this state, it works like a phone that can receive and send SMS messages.

What cause it should be looked at in more detail. please generate the troubleshoot file and send it to me via private message. Go to System → Administration → Troubleshoot.

Please see PM :)

I think I have solved this problem.

To prevent the modem using voice connections, I used the AT command

gsmctl -A 'AT+QCFG="servicedomain",1'

To be super sure that it runs every time, I added this line in /etc/rc.local

I also do a full reboot after 2 failed pings (every 15 minutes) to prevent getting stuck in a non-connected state. For some reason, just doing the modem reboot did not work as well.
