RUT241 Not switching to WiFi - mwan3/mwan3track bug - ifdown event fires on empty device

Networking Solutions Issue
1

Hello,

My RUT241 has not been switching from cell to WiFi. It’s been a long battle to actually figure out why this is happening. You’ll notice I run mwan3 use wan1 ping -c 20 1.1.1.1 with perfect success - so the wifi network is working.

Luckily, I come armed with knowledge!

Here’s what I notice:

  • wan1 pings 0% loss, and the tracker’s last word was “is online” (13:27:51) — yet mwan3 status says offline 39m. Tracker and route-layer desynced again.

  • The cause is right there: every ifdown fires with device (unknown), and at 13:22 it even logged Interface wan1 () is offline with an empty device. mwan3 can’t resolve wlan0-2 on the down event, so when the tracker climbs back to online the routing layer never follows.

  • Two things this capture adds: your ps is clean (no duplicate tracker), so the desync itself is the fault — not stray processes. And look at the gap: it sat offline from 05:52 to 13:22, ~7.5 hours untouched. Once it desyncs it stays stuck until something pokes the interface. That’s why you keep finding them parked on cell.

I have about 10 RUT241s and many times a day this happens. Feel free to give me things to run in the terminal to debug more - it will happen soon and will happen again!

Greetings, @frmssmd ,

Welcome to Teltonika Community!

Thank you for the thorough investigation and detailed logs — they have been very helpful.

SUMMARY

The logs confirm a desync between mwan3-hotplug and mwan3track. When wan1 drops, mwan3-hotplug fires an ifdown event with an empty device name (“unknown”), which prevents mwan3 from properly updating the routing layer. mwan3track then recovers and marks the interface online, but the route is never restored - leaving the device stuck on mobile until something externally triggers an interface event.

Could you please clarify the following:

  1. What firmware version are the affected devices running?
    cat /etc/openwrt_release

  2. How is the wan1 interface configured? (Protocol, and whether it is set up via WebUI or UCI/custom config)

  3. Are all ~10 devices affected equally, or only some of them?

Additionally, please run the following on an affected device immediately after the next desync occurs (wan1 shows offline in mwan3 status but ping via wan1 succeeds) and share the full output:

  1. Routing table:
    ip route show table all | grep -v ‘fe80|ff00’

  2. netifd interface state:
    ubus call network.interface.wan1 status

  3. Extended log (200 lines):
    logread | grep -iE ‘mwan3track|mwan3-hotplug’ | grep wan1 | tail -n 200

We will review the output and follow up with next steps.

Best regards,
V.

WebUI. I tried it keep it simple as possible. MultiAP is used for the WiFi WAN.

BTW: at the end there are some screenshots of how it is setup up in the webui.

As far as I can tell, yes. As of Monday AM, two of the robots had failed. I grabbed the outputs from both of those.

I’ll add a couple screenshots from the webui of robot B:

Thank you so much for your help! Hope this is enough to track down the bug. I did update to the latest version of RUT241 firmware on one of my robots - (not either of the two that failed) so if that one fails as well I will post here.

@Vilius Do you have an update for me? Was the team able to look at the logs?

Hello, @frmssmd ,

Apologies for delayed response and thank you for providing the detailed logs.

Based on the information shared so far, it appears that the WiFi interface successfully reconnects and mwan3track detects it as online, however mwan3-hotplug occasionally generates an ifdown event with an unknown/empty device name. This results in the routing state not being updated correctly, preventing traffic from switching back to the WiFi WAN interface even though the connection itself is operational.

To continue the investigation, could you please provide the following information after reproducing the issue?

  1. The output of:
mwan3 status
  1. The routing tables:
ip route show
ip rule show
  1. The complete MWAN3 configuration:
uci export mwan3
  1. The network configuration:
uci export network
  1. The wireless configuration:
uci export wireless
  1. Please confirm whether the issue can be temporarily resolved by manually restarting the WiFi WAN interface:
ifdown wan1
ifup wan1

or by restarting the MWAN3 service:

/etc/init.d/mwan3 restart

If either action restores failback functionality, please let us know which one resolves the issue.

This information will help us determine whether the problem is caused by the MWAN3 routing state becoming desynchronized or whether there is another underlying issue affecting the interface state.

I look forward to your reply.
V.

Whoops! Sorry for the delay.

Of the 13 robots near our WiFi - 3/13 were on cell.

The problem occurs on modems version RUT2M_R_00.07.22.4 and version RUT2M_R_00.07.21.3.

Logging into one of the modems - first on the webui to check the problem is happening:

Confirmed - I see wifi on standby, when connected.

After running

ifdown wan1
ifup wan1

I saw the multi ap status go to “starting”, and then the failover fixed itself, and then multiap status went to “connected”. See below.

With one of the other devices (this one Firmware: RUT2M_R_00.07.22.4), I connected and tried the mwan3 restart as well.

Hello,

Apologies for the delayed response.

If I understood correctly, restarting the interface resolves the issue. As a temporary workaround, you could consider creating a custom script that detects when the connection becomes inactive and automatically restarts the interface.

Please note that developing or troubleshooting custom scripts is outside the scope of our standard technical support.

If the issue still occurs with the latest stable firmware release, we will require additional information for further investigation, such as a troubleshoot file. Please be aware that troubleshoot files may contain sensitive information, including passwords, public IP addresses, serial numbers, and other device-related data.

To protect this information, we have sent you a secure form to the email address associated with your Community account. When completing the form, please enter 19680 in the Ticket ID field.

Please let me know once you have completed the form so that we can proceed with the investigation.

Thank you for your cooperation.

Kind regards,
V.

Hi, received the instructions, just need to grab the troubleshoot file when the problem is happening. Today or Monday. Thanks.
