Let me start by saying I am a big fan for the teltonika units and have recommended them to many people with off grid installations.
We have used the RUTX12 for about 1.5 years after 7 months the unit failed the standby light was on but nothing else. The RUTX12 we are using is a critical backup for us. We sent the RUTX12 back and waited 3 months for the repair. In this time, we had no choice to buy a backup for the RUTX12 we bought a RUTX09. After getting the unit back it ran for 6 months, and we have a fault again this time all the sim lights are flashing we tried everything to access and fix the unit. We are now using the RUTX09 again and we had to add in a wifi router as a temporary fix.
Now the unit is out of warrenty what are we supposed to do? Is there a know issue with these?
Thanks
Richard.
