I have an RUT240 configured in bridge mode. Every 60 minutes (pretty much exactly), the Ethernet interface disconnects from my firewall. I have spent many hours testing to be sure this is not a fault with my firewall or wiring. I have concluded that the RUT240 for some unknown reason is causing the Ethernet link to disconnect, them momentarily reconnect.

The modem is running firmware version: RUT2XX_R_00.01.11.3

Can anyone assist me with this problem?

I’m experiencing the same. Hope for a quick solution.

I'm currently having the same issue as all the above, bought this as it seems the best option for a 4G router with bridge mode, however looks like if this firmware isnt fixed soon it makes it fairly useless paperweight.

Any update on a firmware fix for this? Or if the test firmware is stable and working well?

This needs addressing sharpish, as I'm sure with Three's new unlimited 4G broadband in the UK, and considering the price is so for the monthly sub, a lot of people will be jumping on this band wagon.

Please can you let me know if there is a fix in the pipeline and soon, as if not maybe I'll return the RUT240

Hi there — I have been running the test firmware for a while now, and I would say that it is stable (it has been running well). Maybe give it a try. Yes, I agree, this has been ongoing for months now; not sure what the hold up is.

Hi Hayden, 

Thanks for the reply, just to confirm the test firmware is the one in the link below: 

Rut2XX Test Firmware
https://kaunas.teltonika.lt:444/d/4aec334a630a458fa7ef/

Which is Verson 00.01.11.255?

Thanks

by
Yes, that's the test firmware that I'm running on my RUT240.
by
At last, Teltonika have released firmware version RUT2XX_R_00.01.12, which appears to have resolved the issue.
by
im getting really poor performance using the new firmware, high ping and drop outs i wasnt seeing before. Anyone else?
by
Hi — Sorry, no; I am not seeing the same performance issue that you have mentioned with the new firmware. Maybe try rolling the firmware back to the previous version, and see if the problem goes away?

Hello. 

If you have no problems accessing the Web Interface of the device, It would be helpful that you can Change the user and password of your Router to a very generic ones, So we can replicate the issue in one of our routers with a set of files I am going to ask you to send to me via private message.

1.- We need you send a draw diagram of the topology you have implemented. The admin and password of the router 

2.- Please, use the device until it presents the problem and then after that without turning off download a Troubleshoot file, and send it to us (Again all cia private message)

https://wiki.teltonika.lt/view/RUT240_Administration#Troubleshoot

3.- A Backup File of the device.

https://wiki.teltonika.lt/view/RUT240_Administration#Backup

In this way we can advice what would be the right way to proceed and who you will need to contact in case this need further attention.

Hello. We have a test Firmware with some fixes. Its a test firmware intended for RUT9XX, so please don't implement it massively, it's for test purposes only
Can you please implement it and give us feedback?

Hi. Thank you for the follow-up message. I've had the test firmware installed for a couple of days on my RUT240 and it appears to have stopped disconnecting the Ethernet interface every 60 minutes.

Looks like your fixes have worked.

@hayden_spence

Thank you very much, We would really appreciate if you can provide a troubleshoot file of the new tests via Private Message.

Kind Regards

jpteltonika —

I've sent you the troubleshoot file as requested via private message. Let me know if you need any more information.

Im having exactly the same problem with same setup (bridge-mode, LAN cable plugged/unplugged and so on), and its affecting my gaming online and chromecasts pausing Spotify and TuneIn every now and then. Hope for a fix with FOTA soon.

Thanks

To jpteltonika in response to my comment four days ago.

The information is from a RUT240 (RUT24006E000 with serial number 1105559562) that is used "in production". Hence, it is not used to test the issue. The unit's firmware is RUT2XX_R_00.01.11.3. The unit is used in Bridge mode with mobile data connection as main (and only connection, i.e. no WAN Failover). 

Here's my view on what's causing the issue: 

1) the hardware
2) the software (firmware), or
3) the carrier

In the case of a general hardware or a software issue, you should be able to reproduce it without the need for log files.  

I'm not an expert, but the irregularity in the number of hours between "unplugged" and "plugged in" (sometimes shorter than the lease time, other times longer than the lease time) indicate a hardware or software related issue. 

  • Shorter than the lease time: I don't understand why the internet connection would be lost after an hour if the lease time is two hours. 
  • Longer than the lease time: Could it be that not all events are being logged? 

Further, perhaps you should consider changing the event text in a future firmware release because unplugging/plugging in the LAN cable isn't what triggers the event log entry. 

Searching the forum, I find one post from 17 July 2019 (Regular LAN port plugged/unplugged events, N.B. for a RUT950), one from 28 December 2019 (Cable unplugged), and one from 6 February 2020 (RUT240: LAN cable unplugged / terrible performance until reboot) all seemingly describing the same issue. This thread was opened more than seven weeks ago. The one from July soon 8 months ago. Hence, should it be a firmware issue, then it's not only affecting the latest version. Should it be a hardware issue, then either not all units are affected or the majority of the users haven't discovered the issue yet.

The router's product page describes it as delivering "high performance for mission-critical cellular communication ..." (my formatting). With such a statement, I believe it's fair to expect Teltonika to prioritizing investigating and solving the issue. Would I have known about the issue discussed in this thread (and in the others referred to above), I wouldn't have bought the unit, nor would I recommend it to be used for "mission-critical cellular communication". 

Should they, as implied in the comment from jpteltonika on 6 March 2020, consider it to be a carrier issue ("the carriers have the tendency to drop lease connections at a fixed time, some times at 3600 seconds others at 7200 seconds"), then they should probably not market it as to be used for "mission-critical cellular communication".

Should it be needed, I can send you log files. If so, please provide info on how to do that via private message. As moderator you should have access to my e-mail address.

Hoping for a quick resolution.

Hi again (see post to jpteltonika a few minutes ago): I've now created an account, and see the possibility to send a private message. Posting when logged in you should certainly have access to my e-mail address if you need to contact me directly.

Hi Börn, we are not allowed to contact via mail. The information exchange should be performed completely on this platform, it can be in form of posts or private messages.

Regarding the previous comment. When the complete circle of communication relies on multiple parties, as in the case of cellular communications, we only can ensure that we are going to do all our best to fix and understand the issues that are under our complete control.

At this moment we have engineers working to understand what is causing those connection dropouts in this specific case, and that information is obtained via log files, as we don't have control on the sim cards. We need this understanding because we have many success cases where this issues are not happening.

We can offer you better attention if you can contact your local sales manager and provide more insights of your specific projects, so we can offer you a handful number of solutions gained through our experience working with several clients with different clients around the world.

In the meantime we are working in some test firmwares so you can provide us with de feedback needed to help you to overcome this situation.

Best regards
by
To jpteltonika: The troubelshooting files have now been sent.

I installed the new firmware (RUT2XX_R_00.01.12) a few days ago and can't see any LAN cable unplugged/plugged in events. So far so good. I'm glad the issue could be resolved.

Thanks for your contribution. As of this moment, we're all still waiting for Teltonika to release a proper firmware update for this issue. I know nothing more than what is mentioned in this forum topic.

We have also exactly the same problem with same setup (bridge-mode, LAN cable plugged/unplugged every  9 minutes past the hour. But only in bridge mode !! / RUT950 - RUT9XX_R_00.06.05.3

Hi!

EDIT: Testing RUT2XX_R_00.01.12.1 right now, will reply later.

EDIT2: The RUT2XX_R_00.01.12.1 did not work either. Should I try the https://kaunas.teltonika.lt:444/d/4aec334a630a458fa7ef/ ? @jpteltonika

@MLehmann: How is it going for you? Did you get rid of the cable plugged/unplugged behavior?

Has anyone managed to solve this problem with a newer firmware?

I have RUT2XX_R_00.01.12.1 firmware but have not been able to solve the problem. This is becoming a major problem as the music and online gaming get interrupted every now and then.

@Teltonika: Are you still working on the problem?

I wanted to drop in to say I have a Verizon model RUT240 and am experiencing data disconnects  ranging from every 2 minutes to every 60 minutes but with my other modem (GL.iNet x750 with Quectel EP06-A) I experience zero problems with the exact same SIM card, APN, etc. I tested the 1.12.2 firmware today and it did not fix the problem.

I can access the Web UI and everything well, but the data connections disconnects and resets as above. Also, I have great signal at -55.
