I have the RUTX11 set to use the 4G / LTE SIM for Fail-Over only but in the last 3 weeks its using 100 MB (50 up and 50 down)?

I replaced an RUT950 with this RUTX11 and never saw the 950 use any data... how to I fix this on the X11?

thx!

I've tried several times early today and again just now to turn on TCP Dump file. It will not turn on... I select the button to turn on, choose the mobile interface from drop-down and click 'Save & Apply'... the screen refreshes the setting is Off again. Am i missing a step?

4G LTE now gets connected as roaming for quite a while but frequently changes to 'Searching'. The 4G signal is strong (see prior screenshots and new one attached from today. I'm pretty confused and frustrated as I have not touched the RUTX11 in a few days and it just started working, sort of??

Hello, 

To get the TCP Dump file you need to enable it in System > Administration > Troubleshoot > TCP dump file Enable it then save then wait for 5-6hrs and download the TCP Dump file then share it with me.

I installed it, it defaults to lan1. After 7 hours the TCPdump file is 0 bytes -- I cant even attach it to this post, the website will not allow it since its zero bytes.

Not sure what to do not, should I run it on one of the below interfaces instead?

Hi itek,

Could you share with me a copy of the troubleshoot file when the issue appears.

Thank you

I have, a few times now. The issue ALWAYS appears. It never works properly, it always uses 4G data when connected to a 4G network even when not in failover... as I've shown in every post with every graph and posted a few troubleshoot files and a TCPdump.

If your engineering team needs to remote in to look at it in-person I'm happy to schedule that. I'd like this fixed, right now I have it turned off because it costs me money to use 4G data. 

as a reminder, last message (way below on this page)...

Hello,

Regarding the issue, you are having could you share with me a copy of the troubleshoot file when the issue appears because the TCP dump file is just issuing pings. We need to get a copy of the troubleshoot file for analysis.

I'm getting frustrated. Can I talk to the person working on figuring this out? I've been VERY clear on what the bug is.

This has been going on for 1.5 months now and I provided you a troubleshoot file, in this thread, on July 29th.

Of course the TCP dump is showing Pings, I told you that is what its doing. PLEASE give this EXACT info below to the engineer working on this...

BUG:
When RUTX11 is NOT Failed Over it is ALWAYS Connected to 4G and thus sending Pings.
-- RUTX11 should NOT be Connected to 4G and NOT be sending Pings when its NOT failed over.
When I force it to 3G it stays Disconnected so 3G seems to work fine.

If this could be a hardware problem, send me a new RUTX11 and I'll test it and let you know. I dont have a spare one of these, they are expensive.

I've spent over a month trying all sorts of settings. Before the last time I sent the TCP Dump file I...

  1. Factory reset
  2. Bootloader flashed and using the latest firmware.
  3. Manually set up (did not restore backup) everything

Attached is the TCP Dump and Troubleshoot file from today. 
Failover was DISABLED then I ENABLED it and in the graphs you can see it started sending Pings immediately but before that was not.

Please fix this, it costs money to use data. At this point I cannot use Failover at all since it uses data when not failed over.

 Hi, 

Kindly try removing the IP address in the Failover settings for the Mobile interface it should look like this: 



Delete the default IP address in the Track IP field. 

Let me know the results

Mellow

by anonymous

Same result. As soon as I turned on Failover it started doing pings and using data. If you're engineers can't remote in to debug this and fix it the send me a new unit and lets see if you have a defect in your hardware

If all the settings are correct and your engineers cant figure this out then send me a new unit and I'll test it.

I've spent a TON of my time and I cant use this device as it was designed. Clearly there is a major bug with 4G Failover there is not with 3G.

Hi what was your fix for this as i  just think i got over a wifi issue but then noticed a few kb flowing through rx/tx in the interface tab for the sim card slot when not in failover to the sim? I thought the solution was in the advanced tab for the sim where i switched off "bring up on boot" thinking from the terminology used for bring up on boot it would mean on reboot the init would keep the sim powered but do nothing with the data until the failover kicked in . This didnt seen to be the case in rx/tx status a few kb of data was still seen flowing on reboot.

Now that wouldnt be a big issue with my current test sim as its totally unlimited .And some providers will actually switch off sim  / not roll over data etc  is unused for few months , forcing you to use pings . However for the final deployment of the router i may have to use a pay as you go sim with non of those terms  ,i.e in total reserve i.e nothing used from data until required or i decide to ping the sim manually . Im running the latest firmware on both os and modem so i dont believe that in itself will be the fix , Can you please share your fix . Thanks

Fix = factory reset and flash back to Firmware RUTX_R_00.02.05.2

... since doing that its been working perfectly for months.  Recent firmware releases have ton of bugs which many people have documented (4G usage, UI freezing, setting not saved, etc)

Hello, 

For the failover issue you are having with RUTX11 could you try configuring the flush connection settings? You can do it by navigating to Network > Failover edit the rules of mobile and wan.



So that where there is a failover happening all the devices that is currently connected will be also refreshed.

Kindly let me know the results

Regards,
Mellow

to be clear, the issue is not about Failover... the RUTx11 is using 4G traffic/data when not failed over.  Tshoot file ... https://community.teltonika-networks.com/?qa=blob&qa_blobid=17375583763514820083

Should it not simply 'register' on 4G and stay Disconnected until a failover occurs? 

No matter what I set -- IF it registers on 4G it Connects and uses data even (when not in failover!)
-- must be a bug, yes? 

Some testing I did...

"AUTO" also registers on AT&T
Forcing to T-Mobile does register but still Connects and uses data
Both always show as roaming.

Often it connects to 4G for few minutes (and eats some data) then change to Searching and connect to 3G and stay there unless I reboot or change a setting.

Changing settings...

1. Result = 4G, Connected, T-Mobile, Registered (roaming)  **data transfers

  • Manually set APN (no authentication)
  • turned OFF Deny Data Roaming
  • set Service Mode to 4G (band selection = Auto) 

2. Result = 4G, Connected T-Mobile, Registered (roaming)    **data transfers

  • changed :: Service Mode to AUTO
  • rebooted (unplugged power)

3. Result = Disconnected & "Searching", 'State' loops between 3G<->4G constantly, AT&T

  • changed :: turned ON Deny Data Roaming

4. Result = 3G, Disconnected, T-Mobile

  • changed :: set Operators to Manual and selected T-Mobile (same as what it selects when in Auto during Test 1 & 2)

 5. Result = 4G, Disconnected, Operator = N/A, Operator State = Unregistered

  • changed :: turned OFF Deny Data Roaming
  • changed :: Service Mode changed to 4G (LTE) Only

 6. Result = 4G, Disconnected, Operator = N/A, Operator State = Unregistered

  • changed :: turned ON Deny Data Roaming

 7. Result = 3G, Disconnected, T-Mobile, Registered (roaming)

  • changed :: Service mode = Auto

 8. Result = 4G, Connected, T-Mobile, Registered (roaming)    **data transfers

  • changed :: turned OFF Deny Data Roaming

Hello, 

First of all the issue, your device is using data when it shouldn't when you are on a Wired network not on Mobile data. 

Here is the result for mine: 

There is a 4.23MB usage I will check this with HQ and see what may be the cause for this one.

Hello,

Regarding this issue of yours would it be possible to leave the device turned on for around 6-7 hours and get a copy of the TCP Dump file for analysis.  

Looking forward to receiving the said file.

@Mellow

Now it will not connect to 4G if I try to force it to. In AUTO it connects to 3G and does not use data but nothing I do gets 4G to connect, only shows 'searching' with Deny Roaming On or Off, and forcing Service Mode to 4G

this graph shows when it was connecting to 4G and using data, then it changed to only connecting to 3G and not using data...

Hello,

Regarding your issue, it is best to do a firmware re-flash via the bootloader menu and check it again. Is this sim card used in roaming or no? Kindly make sure both mobile antennae are connected to the device and you have good signal quality from your Mobile ISP provider.

As mentioned once connected try to to make the device run for 5-6hours and get a copy of the TCP Dump file and share it with me for analysis.

I did a complete factory reset on the RUTX11, then flashed the new .07 Firmware

Then I ONLY changed I made was to add firewall rules to pass though needed traffic and Failover enabled... NOTHING else.

Now 4G LTE always show CONNECTED (tried Service Mode in Auto and 4G Only) even when not failed over. And there is traffic flow.

I went to get you a TCP Dump -- setting No Longer Exists! (see screenshot)

From the last screenshot of the Traffic, you can see a CLEAR pattern. Looks like a ping or something constantly going. I suspect it does when 'Connected' and detecting for a working connection? But the problem seems that it should not be Connected when not in Failover. Arg.

Hello, 

You need to install the TCPDump package in the Package manager (Services > Package Manager) in order for it to appear in the System > Troubleshoot.

OK, installed. set the Interface to "mob1s1a1". Will post file here in the morning... 4G is using a lot of data!

Hello,

More info for you, and new dump files attached.

https://community.teltonika-networks.com/?qa=blob&qa_blobid=15134661125039436015

https://community.teltonika-networks.com/?qa=blob&qa_blobid=16923267446137735547

I changed the ping time from 3 to 5 seconds and now I'm 100% sure the traffic is the ping. You can see on the graphs the distance between the spikes is wider than on the prior screenshot.

When I disable mobile under Failover menu (usage chart attached) no traffic is used, at all... but the mobile SIM stays in the 'Connected' state.

The issue is clearly that Failover is not working properly in this .07 FW or prior one at least. Thus, when NOT in Failover it keeps the mobile SIM 'Connected' when it should be 'Disconnected', and thus the traffic are pings that should happen ONLY when Connected in Failover.
