Last week I added two Teltonika RUTX50 routers to the web control panel. One worked right away and is running stably, along with the five similar I previously added.
But the other one is extremely unstable. It took about five hours before the connection was stable enough to update the router’s firmware. It seems like it’s rebooting or losing the signal to the mobile network and keeps searching over and over.
I’ve tried a factory reset, and then there was actually a stable connection for about half an hour, but then it’s been unstable again. I’ve changed SIM cards and tried both SIM slots in the router, but it doesn’t make any difference. I’ve also tried placing the router in a different place, but that doesn’t make any difference either.
I have a similar router in the same location. It’s stable and without any dropouts. I’ve also tried several locations with the unstable router and it’s the same problem everywhere.
Yesterday I tried moving the router to another new location. After some time there was finally a stable connection, and it was connected all night. When I connected a computer to the router this morning, it started again searching for a signal from the mobile network and now it loses signal again and again.
First we would like to evaluate general state of the device prior to making any assumptions. Modem firmware upgrade, could be a potential next step that we will perform if necessary after all the information is available.
Could you check mobile signal strength by going to Status>Network>Mobile
You can see Mobile signal strength recommendations in link provided:
Please try switch of Auto APN and choose manual instead. If you don’t know which APN to use you could double check with your provider so he can provide this information to you. You can do that simply by going to: Network>Mobile>General
Also if you running an older firmware please update it to the device (RutOS) latest stable version.
If non of these options helps to resolve your issue we will send you request to hub spot platform.

I’ve already tried changing APN settings etc. The only option that provides a stable connection without dropouts is if I set “Preferred network type” to 4G/3G.
I’ve had six RUTX50 routers (the version without sSIM) and eleven RUT241 routers in the exact same location as this one. The 17 other routers have worked perfectly fine - only this one is causing problems with an unstable connection. There are many users here on your community reporting the exact same problem with this modem and this FW version.
To me, it’s clear that there’s a problem with this modem and a 5G connection, so if you can’t fix the error, you’ll have to have the retailer take the router back.
Thank you for your swift response! We will be conducting a further investigation into this matter and will need some additional information from you.
