RUTX50 - Mobile Data Disconnected (UK)


(First post) Nice to meet you all and thank you for looking at my comment…

We recently got a RUTX50 and had 3/4 days of 5G bliss… however, we started getting dropouts soon after with the predominant error: Mobile Data Disconnected…

(Smarty network/Three apn… which is dialled in manually) external antenna… tried various fixes suggested here… we managed to get online for around six hours last night which was a recent record…

It’s strange… when it works, it works great… Apologies if I am vague, but I can provide as much more info as you need.

Thank you again!


To start off, make sure you are running the latest device and the internal modem firmware version. Currently, the latest RutOS version is RUTX_R_00.07.04.5, and the latest modem firmware is RG501QEUAAR12A08M4G_04.200.04.200.
If you are already running the latest version, I will ask you to wait for the issue to replicate, navigate to System → Administration → Troubleshoot, open the System Logs and copy the last logs around a minute before the loss of connection. This may help me identify the issue. Make sure to remove any sensitive information.
Finally, I’ll ask you to take a screenshot of the Status → Network → Mobile page. Make sure to hide IMEI, IMSI and ICCID.

Best regards,

Thank you so much for your assistance, Daumantas!

I can confirm the firmware is up to date… and I will get those logs for you shortly :slight_smile:

It seems like for some reason the modem stops responding and then after some time re-establishes the connection. This could either be a software, or hardware issue. To dive deeper into the issue, we would need a private communications channel, thus I’ll ask you to contact your sales manager, reseller, or fill out the Contact Us form here: Teltonika Networks - LTE Routers, Gateways & Modems for IoT
