Hi there, using RUT955, dual SIM mode. Can anyone throw any light on why my router's mobile connectivity is so unstable. The timestamps show it rapidly cycling through the same stuff all the time. Looking at the logs I see constant disconnects, reconnects, "Unknown" network type, "N/A" for mobile data. The Wifi connectivity also seems very unstable too. I have an excellent antenna connected (poynting Puck 5 in 1).  I know that the internet connectivity works as I have tested it on both SIMs and get excellent speeds. Obviously with a vehicle moving around that will vary. The below log was taken from a excellent coverage area today. Interesting, it doesn't appear to try switching to SIM 2 (I have it configured for when signal strength falls below -85dBm, No Network, On Network Denied, On data connection fail with a check interval of 5)

Hello,

I want to check the issue in more detail. Please generate a troubleshoot file and send it to me via private message. Go to System -> Administration -> Troubleshoot and click Download.

Hi Marius

Thanks for offering to take a look. I sent you PM , I cannot send the debug file, the private messaging system will not accept it. Can I email the .tar file to you?

Hello,

According to the troubleshoot file, I can see that the signal level changes slightly, but sometimes the signal quality (RSRP) decreases. However, this should not be significantly affected.

Did you try to reset the router to default settings? If so, then try to re-write firmware without "Keep all settings". Latest firmware you can find here:

Hi

Thanks for taking a look at this for me!

I have not tried to reset the router. I think what you are saying is do a reset to default settings (it already has the latest firmware on it, do I need to write the firmware again?), but then you want me to configure it from beginning and not use the restore file (backup on config)  ?

The problem is a bit odd, the signal level is generally OK. It's causing us a problem in our operational setting, we have considered trying a different manufacturer/router.

Hello,

Before overwriting the firmware, you can download the Backup file and after overwriting the firmware, upload the Backup file to preserve your existing configuration.

Your signal level is good, but SINR sometimes drops to 7 dB and RSRP at -91 dBm. These poorer signal quality parameters can cause the Internet to disconnect. You can read the Mobile Signal Strength Recommendations here:

https://wiki.teltonika-networks.com/view/Mobile_Signal_Strength_Recommendations

For better signal quality parameters, I recommend using both SMA mobile antennas. Also, if possible, move the router closer to the window to make it easier for the signal from the base station to reach your router.

Hi there

I can take a backup and then restore, but what if the fault lies within that config and restoring back may re-introduce the issue?

I had upgraded the firmware to latest back in march 2020. I am wondering whether to get a new RUT955 in case it is faulty in some way.
by
I doubt this issue is caused by the configuration. Therefore, it is worth trying to rewrite the firmware to reject the firmware issues. However, pay attention to the LTE signal parameters because, as I mentioned, SINR and RSRP seem to have a big impact on disconnections in your case.
