Tried searching the forum for help, but could not find anything that seemed related.
I upgraded my RUTX50 to firmware RUTX_R_00.07.07.3, and after the upgrade the internet connection stops working after around 1-48 hours (kind of random last few days). When it looses connection to Internet, the only thing that works is to reboot the device (Network → Mobile → Restart Connection does nothing).
I tried to remove a few 5G/LTE bands according to another post here, but it does not seem to do anything. When it has disconnected the GUI still shows that it’s using the same bands that it did when it worked. Have also tried to downgrade the firmware without success, also made a complete reset of the device with the same result.
Have you tried a factory reset and seen if that makes a difference?
Also … How are you checking which bands to try because when I saw a similar problem, it was because I’d be ticking along fine until atmospherics started having a say as to which bands ended up being useable.
Selecting which bands to use is very much a case of experimentation but can be guided somewhat by using a tool such as Cellmapper.
Install Cellmapper on your phone, insert the SIM of the RUTX into phone. Turn off WiFi and if a Dual SIM phone, disable the non-RUTX SIM.
Open up the app and it will scan for available bands … from then on, use this insight to try on the RUTX … as I said, a case of experimentation but worth a try.
Be aware that the app runs in background mode, so even if you close the screen, thinking the app is also closed, it will still be running and consuming valuable battery. Depending on your phone OS, you will need to close down the background app.
Thanks for your reply. I tried a factory reset (holding down a pin on the reset button for 10 seconds, right?) with not luck.
Regarding the bands I read somewhere here on the forum that a few of the LTE bands could be problematic. Tried removing them without success, and then I locked it to only use the bands I knew worked after a reboot (3 different LTE and one 5G) to test if the issue was caused by the router changing bands, but no difference. Now it´s set to automatic again with automatic reboot when the router can´t ping 8.8.8.8, so it reboots when it locks up, somwhere between 1-48 hours.
Pretty sure it´s firmware/modem firmware related since it has been working great for the last year, and problem started when i upgraded the firmware around a week ago.
Found another thread where someone could get a newer modem firmware to test with. If anyone from Teltonika sees this and thinks that it could solve the issue, please send me information on how to upgrade the modem fw.
10 seconds on the reset button MIGHT not be enough … checkout the instructions below for the RUTX50.
The reset button has two functions:
Reboot the device. If the reset button is pressed for up to 4 seconds, the device will reboot. Start of the reboot will be indicated by the flashing of all 3 signal strength LEDs together with the green connection status LED. Factory reset. If the reset button is pressed for at least 12 seconds (by default), the device will perform a factory reset and reboot. Signal strength LEDs indicate the elapsed time while holding the reset button. Start of the factory reset will be indicated by flashing of all 3 signal strength LEDs.
NOTE: the default button hold time value (min time 12 seconds, max time 20 seconds) can be changed in the router’s WebUI, from the System → Administration → General page.
With regards to the latest modem update that I’ve seen requested, I very much doubt that it will make a difference, but I’m always ready for an expert to prove me wrong.
I derive that you’re using the PING/WGET REBOOT … for info, in case you are unfamiliar with the options, it’s enough to do a ‘Modem Reboot’ not a ‘Device Reboot’, to get the RUTX to re-establish a new connection. Saves on ‘outage’ time on the reboot.
Mike was correct; 10 seconds is not sufficient for a factory reset. To perform a factory reset using the default settings, you need to hold the reset button for 12-20 seconds. However, it seems there may be additional complexities. Could you please share the troubleshoot file? Due to its sensitive nature, we will handle it on a separate platform. Instructions for accessing it have been sent to the email you used to register for this forum.
Thanks for all your replies @Mike - Will try the modem reboot as an alternative as well, however I’m leaving the summer house where it’s placed in a few hours, and another family is living here the coming week, so will try that setting (together with the nightly reboot if it does not work, so that I can connect to it when not here) when they have left.
Thanks @Marijus - I think I held the reset button for more than ten seconds. The router was reset to the same state when I first bought it, so I guess that would be equal to a factory reset. Thanks, got the e-mail and replied, and have the troubleshoot file ready to be uploaded.
From the file, it doesn’t appear that there are any issues with your mobile connection. I can see that you have set up a PING reboot as well. To identify the problem with your mobile connection, I’ll need to troubleshoot where the issue is occurring and when it’s visible. This means you’ll need to get troubleshoot file when the device loses internet connection before rebooting it.
Thank you very much for your help. I left the house where it’s located yesterday, and can only reach the device through VPN when it’s working, so I won’t be able to send you a troubleshoot file until I’m there in person next time (probably not until next year).
I’ll hope that it’s firmware related and fixed in the meantime. Thanks!
A major firmware release is imminent. If it does not solve the issue, please let us know. When you get the router’s troubleshoot file, please come back and create a new topic with this topic tagged too.
