RUTX50 5G connection dropout (att. AndzejJ)

I had a 24hrs smooth operations but last night it frose again and only a power cycle could bring it out. The thing is why is it freezing. In my case I have a solid power supply on a Teltonika charger and that cannot be the issue (I think). I might have connection issues with the tower. But even if I have no connection it should not freeze. I think the problem is in the modem somehow. Some kind of dead end check loop between router and modem which kicks in once it loses the connection. They (Teltonika) have been working on the sim card switching and failover but if you just have one sim card there is a risk that it freezes itself (requiring a reboot or power-cycle).

I can’t bring mine back. I am too late already. Its difficult to proof that the router is faulty. I know it is but it’s difficult to reproduce the exact circumstances where it stops.

My dealer basically said that I should bring the router in and “they will check it” - effectively it means I’m not getting a refund, because when they plug it in and it works they will refuse to take it back, saying “it works fine”. I could RMA it, but then again, I have to spend money on shipping it, getting an interim router and then wait for unspecified amount of time to receive router back - with no guarantee it will work… I might just as well use what I got until it fails completely and then splurge on another 5G box from another manufacturer.

Overall this was a pointless exercise in investing in “European innovation”.

You triggered something and I wrote a mail to the company where I bought my router. I think they should know:

Hi,

I feel the need to give some feedback on the Teltonika router (especially RUTX50) and a little bit of my experience with Teltonika as company.

I bought the Teltonika Router with your company somewhere end of March. A RUTX50 5G router ready for the future. It’s actually ready for the bin.

To get a feel of the issues and problems Teltonika routers (and the RUTX50 especially) have you should visit the Teltonika community https://community.teltonika.lt/ and read what users are struggling with including myself.

From my perspective it’s the potentially the most versatile router I ever owned but at this stage it’s ranking as the worst router I ever owned as well.

I don’t know what to do with it. As I am writing this mail I am at the other side of the world (a reason why I bought this router) but If I was not I would swap it for my previous Huawei router immediately.

I have been talking to Teltonika directly and it was rather disappointing as well. They have no solutions . The software is very very poor and the hardware is possibly faulty as well but very hard to proof. For sure and I have truck loads of examples that stability is just terrible.

You guys sell these things and I should hold you accountable as well but I probably end up in a yes no discussion for ever. I take my loss regrettably and these are not cheap routers.

Nevertheless I would advise you to walk away from these routers. Not worth it and you cannot sell these routers in good faith and with dry eyes to your respected customers.

Best Regards

Hi,

Welcome to the madness :smiley:

I’ve half-given-up on trying to fix it, but just out of stubbornness I’m collating observations whenever they are relevant or not.

To begin: the firmware on router is RUTX_R_00.07.04.5, the modem firmware is RG501QEUAAR12A08M4G_04.200.04.200, kernel 5.4.229.

Router is set to reboot every day at 03:00 and “reboot on ping” is on: int 3 min, timeout 10, int count 2.

After I have updated to 07.04.5 the 3 LED hangup thing was reduced to an extent, I have had it 3 times since update 3 or so weeks ago. Twice on the day after update, once since. Once modem lost connection but managed to reboot itself.

I have recently tried disabling all wifi on the RUTX50 and using R7000 with FreshTomato for the WiFi output. No idea if it makes any difference, it’s a recent implementation. The only logic behind this is to reduce any software conflicts if there are any by not having WiFi running.

In Stockholm suburbia I get about 210-300 Mbps in the evening, 130-160 Mbps during the day. XPOL-2 is hooked to terminals 2 and 3, bunny ears on 1 and 4. Signal is between -43 and -50.

Overall it works, more or less. As long as it does not get any worse, I can live with it, but Teltonika were next to useless with advice on how to actually fix it.

Hello,

We’re sorry to hear that you are experiencing issues!
Since this is a public forum, there is a limited amount of information we can use to troubleshoot the issue, however, here is some information I’d like to ask for in order to better understand the issue:

  • Insert the SIM card that works well and log into the CLI. Run the following commands:
    gsmctl -A 'AT+QENG="SERVINGCELL"'
    gsmctl -A 'AT+QCAINFO'
    Post the output in the next comment.

  • Insert the other SIM and repeat the same steps after the mobile connection is established.=

  • Make sure your device is running the latest RutOS and the internal modem firmware version;

@DelphiC Perhaps you could try blacklisting the n78 5G band to check if the issue reappears? This can be done by navigating to Network → Mobile → General, selecting the network type as 4G + 5G, adding all 4G bands, and all 5G bands except 78. Thank you.

Best regards,

Hello,

You are running the latest modem and device firmwares, so the “Update available” message might just needed a webpage refresh to disappear. The modem update was needed to address an issue with n28 5G band (which your device is connected to) on some carriers, so hopefully the modem update addresses any instability you have faced.

Now regarding the SIM cards, your old SIM card seems to not support 5G, as it uses the same primary cell for 4G, but does not connect to 5G. So the increase in speed you are seeing is because of 5G availability on the new SIM. This could be caused by either your carrier restricting 5G for the old SIM, or sometimes the SIM itself needs to be replaced to support the newer network technologies.
Let us know if the update helped!

Best regards,

Doing what you suggested result in “Network type” going from 5G (NSA) to 4G+ LTE and my speeds dropping from 210+ to unstable 75-110 Mbps down and from 60 to 20 Mbps up. As before, since original error is intermittent I’d have to keep device in this mode for at least two weeks to get any idea of stability.

Hi aguys,

After claiming the router & referring to this post, I just got my money back from my supplier. My Rutx50 journey is over. Cheers !

Good. Sounds your supplier people are decent and are actually doing their job.

@everyone else
I have managed to perform a “cargo cult” procedure some time ago and set settings that actually made the difference and stopped this issue from re-appearing, AFAICS!

Procedure: reset the to factory and re-flash everything from CLI (to RUTX_R_00.07.04.5), set ping modem reboot to on, 3 min/ 10 s/ int 2.

And for me, this worked:

B7 and B1 are the strongest LTE bands around where I am and 78 is what is in use for 5G. Speeds are 300+ down/100 up.

With that, I do not get “3 flashing LEDs death” any more. Router still looses connection every now and then, but is capable of soft-rebooting itself on its own, without power cycle from me. Also, when I’m in WEB UI under “status network mobile” WEB UI reports occasional disconnect/connect events but it does not affect anything as far as user experience goes.

Major disclaimer: I have no idea if it is settings, something my 5G operator changed in their network configs that made router start behaving better when talking to cell tower or it is related to latest firmware Teltonika pushed out (using RUTX_R_00.07.04.5 now). It was an entirely cargo cult procedure by end-user me. If you suffer from 3 LED death issue - try this. It might help, it might not. You won’t break anything… I think…

Well, thought I come back and say what I think about RUTX50 now.

Believe it or not, Teltonika DID fix most of the bugs. Hat’s off to you fellas. New firmware works a treat and I have not has a single issue since new version was dropped in.

I’d be the first to ***** about problems, but one has to give credit too. When I got the RUTX50 it was really half-brained as far as functionality and reliability went. Now it is the device I bought it as.

Thanks!

Glad to hear your router is working well now.

My router was working well November - December but now it’s near impossible to get 5G and on top of that my router hangs occasionally. I don’t use the wifi on my router as it’s connected to a Unfi Dream Router…it’s so strange it works for a few months and then everything starts to go bad again. Both my Netgear M5 and the iPhones we have in our family get 5G all the time without external antennas… Netgear M5 is the backup that now is the stable one…

One thing that actually makes me mad is that discussing this matter a while back with Teltonika on this forum they reply that they focus on stability rather than speed. Are they saying I bought a Volvo or is it a Lamborghini (according to the glossy brochure) but it only performs full potential when it’s really safe. As of now I’m standing on the side of the road with my Lambo watching Volvo and Fiats passing by…and when I’m lucky it’s stable and drives the Fiats pass by because I can’t get out of first gear…

Meh… that kind thing always sucks. What version of firmware and modem drivers are you running? I only got mine working normally after factory reset and then upgrading everything from there. Was a pain to restore all settings manually, but it was worth it in the end. Reg. 5G - I had some intermittent issues with speed when I had only 2 feeds from XPOL2 and used 2 bunny ears on the other 2 ANT inputs. Since I got second XPOL2 and have all 4 feeds connected to them the thing is blazing fast - up to 250-400 Mbps down, 90-120 up. If your signal is weak-ish and router keeps hopping between bands, you can restrict the bands it uses - it helped me a fair bit before I added second XPOL2.

Thanks for your reply I’m running the latest firmware and I have done several factory resets.

I’m using a Poynting XPOL-0001-V2-41 4x4 mimo on a pole on top of my house roof with the 5m included cables not extended.

I’ve been in contact with Poynting and they have been helpful with the installation. I’m pretty close to antennas in rural area. Mobile phone and Netgear M5 gets 5G indoors without antennas.

I’ve done field testing down town in Stockholm and areas with perfect 5G NSA and there I get 1Gbps down with Netgear M5 and IPhones but only around 400Mbps with Rutx50. Obviously connected with network cable…

I’m curious to know what modem is in the Rutx50 as it seems to act its own life not comparable to other devices. It’s as after upgrading the software it just does not want to do 5G, if I toggle settings 5G works for a while but always goes back to 4G…

I’m don’t want to return the modem to the reseller as they have said they will test it to see if something is wrong, and obviously they will plug it in and say it works and bill me for the testing. I’d be happy to send it to Teltonika for testing instead.

Since wifi is my core business and I’m working mostly from home I have been able to purchase the router in my company for testing so there is no actual loss. Unfortunately I would have had some use for these devices if they worked for my customers and employees in my company but now not so much…

I’ll reply later, not at PC now. Say, can you post screengrab of signal levels and bands? this one?

In all honesty, I don’t bother much with speed as long as it is >150 Mbps on the down - I can’t see the difference from 500 unless I’m pulling massive datasets or something else… But I can see if your are in the IT field and it’s your bread and butter then speed/throughput may be a big issue.

Thanks for your reply, it feels good to discuss with an end user :slight_smile:

True about speed but I do care about ping and ping is excellent as long as it stays 5G. I have two very demanding users here (my daughters gaming) and when 4 users/family members are streaming 4K it’s perfectly OK in 5G (when it works). We run medium size bank offices with 100Mbps and 20 employees so the speed incitement is just a selling argument from our fibre providers, fully agree with you. As you can see ping was 16 in 5G, fully acceptable even for gaming.

I’m beginning to think the RUT50X is hanging/becoming unresponsive because I do LAN LAN with port forwarding thru a switch to my WLC/ROUTER but that’s just theories so far.

What do you know after toggling settings I was on 5G for a while. Il post some pictures in 4g and 5G below. I tend to not allow LTE B8.

Hej,

It’s a bit weird. I never seen “that” when I was having issues. It looks like router just dropping a bunch of channels and ignoring them altogether? Never seen that happen while I was tinkering with mine. Say, can you try going to modem settings and mess with the bands a bit? Switch “Band selection” to manual and restrict to 5G, one LTE band and some useless 3G you are not using and maybe flip Low Signal Reconnect to “on”.

I “know” there is a bunch of shell commands for managing modem behavior though CLI, but alas, I’m not an expert in that. There was a couple of posts in the forum about it where Teltonika guys were giving advice on some issues, but that’s beyond my ken really.

This is what on the router now, firmware-wise:

There was also this issue reported earlier - RUTX50 internal modem firmware issue - #3. Regarding reset - don’t know what you have done when resetting - I did mine from CLI - RUTX50 Device Recovery Options - Teltonika Networks Wiki and also updated from CLI.

And to round it up - a really dumb question - are you certain that your 4x4 is OK? I mean that it has a solid electrical connection to the antenna sockets on the router? What would happen if you put router bunny ears back on? Have a look at this - RUTX50 with 2x2 MIMO antenna? - Crowd Support Forum | Teltonika Networks

PS. I’m also in Sweden. Right now my speeds are “reasonable” for middle of the weekend with people at home, plus I live in an area with a lot of signal bounce off the buildings, I’m sure if I had my 4x4 on the roof instead of a balcony with 2x2 #1 and #2 looking sideways at 45 degrees I’d be easily double that if not more.-

Thanks for your reply, good input I will be looking at resetting the modem.

I’ve tested disconnecting the antennas and it sure makes a difference so I’m sure it’s ok, as you see my signal strength is ok-good.

Router has been running ok for a while so I’ve connected it to my wifi, it’s actually not been hanging up for 5 days until today… it’s strange it all happened when we where downloading a few ps5 games. The router was still accessible so I tried resetting restarting the modem and this is what happened…

As you can see it stayed in disconnected although I restarted the modem several times. After rebooting the router it works again.

I really would like Teltonika to help here, I don’t want to send it to the vendor to have them test it 5 minutes and returning it saying it works. Especially now that it seems to brake down when it’s under heavy load…so much for reliability… please can someone from Teltonika advice here?

Oh, well, saying “all is good” as usually puts a hex on things… :sweat_smile:

One pane now says 5G is connected:

The other fails to see it:

Looks like came after latest update to 07.06.1. I’m not too fussed about it as router works just as before, speeds are fine, but one can’t help but wonder if there are just too many features on this thing - I’m pretty sure everything is working as it should internally, just reading the data gets mashed up.

Patching RutOS must be like herding cats.

Looks alright for me after update. RE: herding cats :slight_smile: it would be great with some release notes for us end users with issues to understand what to expect. Seems like Teltonikas firmware page is down, maybe there are release notes to be found I don’t know, this thread keeps being ignored…

I updated to the latest stable firmware and as you said once the 3 lights are flashing the web interface becomes unresponsive.
