Question

Just tried to install my new RUTX50, but cannot get the 4G/5G-connection working with my provider KPN. I used my (working) datasimcard from my Ipad which gave the same result. Tried the manual settings for KPN, upgraded the firmware, but this doesn't help either. What is the solution for this problem?

Answer 1

Hello,

   

Just to clarify, the iPad also does not connect to the carrier? In this case, this would most likely be the issue on the operator's side or a damaged SIM card. Also, does the device not connect to the carrier at all? Or just the 5G connection is not established?

However, if it does work on the iPad, then there are a few troubleshooting steps:

• Try setting the router to 4G + 5G mode. This is needed for 5G NSA operation;
• Set the APN to internet;
• Make sure the antennas are screwed in properly;

If none of these steps help, I'd like you to replicate the issue, navigate to System → Administration → Troubleshoot and generate a troubleshoot file. It can be attached to the original question and will only be visible to Teltonika moderators.

Both sim-cards work fine on 5G in the iPad. Tried the other settings that you suggested, but still the device does not make contact with 4G/5G. After applying the settings the device sometimes loses contact with the internal modem.

I attached the troubleshooting file to the original question. Can you help me out?

Hello,

  

The issue has been forwarded to our RnD department. I will contact you via private message if anything else will be needed.

Could also clarify if you are using the included PSU?

Thank you for your patience!

I am using the included PSU

By the way. I just tried a normal SIM-card from both Dutch carriers KPN and TELE2 and they both worked fine in the RUTX50. The SIM-card I want to use in the RUTX50 is a special data-simcard which has 12 digits in stead of 10. Maybe that's the problem?

Thank you! I've relayed the information to our RnD.

I'll let you know once we have a solution.

I succesfully excluded the 28-band from the list of bands of both the LTE as the 5G-settings. The RUTX50 now connects to the Internet using 4G.

You mentioned that KPN is the bottleneck in this issue, because they only use the 28-band for 5G. I am currently reviewing my mobile contract. Which are the Dutch providers that I can select to use 5G on my RUTX50?

Hello,

  

T-Mobile seems to also be using the n28 5G band, which has not been reported to cause any issues, so that should work fine. No n78 coverage seems to be available at the moment in the Netherlands.

As for KPN, many engineers are looking for a solution, so hopefully, it will get resolved soon.

EDIT: The T-Mobile n28 band seems to also have issues.
