Weird LTE Connection Downtime and DHCP Issues - RUTX11

NETWORKING SOLUTIONS
1

Hello All,

I’m experiencing a weird LTE connection issue with my RUTX11 router. I’m using a SIM card from an LTE-based home broadband connection, and my connection goes down for 1-2 minutes every day, once or twice.

This SIM card originally worked without any issues in a Huawei LTE CPE, but after I moved it to the RUTX11 router, this problem started occurring.

When I check the logs, I noticed that this issue happens exactly during the DHCP lease renewal process. The udhcpc attempts to renew the lease, and the log line for DHCP renewal is present. However, after a few seconds, it reports ‘mobile data disconnected.’

Could this be related to a busybox udhcpc bug? How can I resolve this issue?

I have attached the logs for reference.

Hello,

Thank you for providing the logs!
I’ll ask you to update the device to the latest firmware, wait for the issue to replicate, then via CLI/SSH run the following command:

cat /tmp/mobile/mobifd.log

And paste the information from the beginning of the disconnection. This log file is responsible for the mobile connection itself, and should contain more verbose logs.
Make sure to remove any sensitive information before posting them here!

Best regards,

Hi @Daumantas,

Thanks for the fast response. Pasting logs here. Please note that I tried to change few setting on the router. these also may be reflected in the log file. Please let me know if these logs are enough.

Hello,

Indeed, from the logs it’s seen that 3 changes in configuration were made (09:27:29, 10:45:40, and 10:50:20), thus the mobile connection was restarted. Could you wait for the issue with DHCP lease to replicate and take the logs then?
Nothing obvious is visible within the attached logs.

Best regards,

Hi @Daumantas

Attached new logs. Today, this happened multiple times and wan interface was keep flapping. My partner had to reboot the router to make it stable again and important logs may be lost during this reboot. Even I had configured remote syslog, modem logs are not forwarded

Hello,

While the disconnection event is not visible in the logs, I can see that the device cannot connect with the default APN to your operator. Please navigate to Network → WAN → edit the mob1s1a1 interface, disable the Auto APN feature and set the correct APN provided by your carrier. It may not eliminate the disconnection issue, but it should reduce the reconnection times, which may also help mitigate the original issue.
It could be that your operator simply refuses to renew your lease, which results in a reconnection, and as the APN is not set it takes quite a while to reconnect.
Let me know how it goes!

Best regards,

Hi @Daumantas thanks for the reply I searched my current provider APN settings but cannot find it anywhere. Mostly they mentioned that use the APN settings AUTO or DEFAULT for their TDD network. I checked the default huawei router as well and there’s no APN configured

Also when I reboot the router it will stay stable for few hours and then again start keep flapping the wan interface. Here another set of logs that I captured when it disconnect. I added it to zabbix monitoring to make sure I get notified when the wan interface go down.

Hello,

According to this article, the APN should be mobitel.
Additionally, I can see from the logs that SIM Switch even took place. Could you double-check that SIM switch is disabled if you are only using 1 SIM? This configuration can be found by navigating to Network → Mobile → SIM Switch.

Best regards,
