RUTX09 firmware update 7.04.4, no more connection through modem

Teltonika Networks
1

Dear Customer Support,
after upgrading firmware to 7.04.4, I’m not anymore able to connect via modem.
I have tried to downgrade firmware to 7.01.4 via webUI but this doesn’t solve the problem.
3G and 4G led are blinking in sequence.
In the system log file, downloaded through the System>Administration menu, I can see the lines below.
(It seems I’m not permitted to attach files to this post).
My modem is identified by the following FW version: EG06ELAR03A05M4G

Is there anything I could try to recover?
Thank you,
Luca

Hi, starting with simple things - could you double check if APN is correct? It seems that router is trying to bring up mobile connection using this APN:
iliad

Is that correct? Maybe it should be something else, for example an empty string or another generic APN value? I’ve seen some carriers accept any random string or an empty value, but then there’s carriers which do not accept anything except some specific APN string so you gotta look out for that.
