RUTX11 consumes mobile data despite Wifi priority (failover)

Dear Teltonika Team,

I set up my RUTX11 (latest FW) so it is permanently connected to my other home router via Wifi. This connection is in the first position of failover connections (name redacted in screenshot below), second is the RUTX11’s mobile (SIM1):

Despite that there are no connectivity problems with this Wifi connection, I observe under “Network > Mobile > Limits > Data Limit > Data used” that the RUTX11 permanently sends data via mobile (SIM1), value increasing continuously:

Have I misunderstood something, i.e. does the router consume mobile data even if its primary connection is via Wifi?

Thanks for your help!

PS: There was a similar post from another user about mobile data consumption despite WAN (not Wifi) connection; however, it was never answered:

Kind regards,

Hello,

Could you please share a screenshot from the Network → WAN section in the WebUI? Thank you.

Best regards,

Hello Marija!

Here it is:

The first WAN interface (192.168.178.64) is my RUTX11 <=> other router connection via Wifi. It gets its IP from the other router’s DHCP.

As you can see, there are high transmission rates (TX/RX) shown for this device, which looks ok to me.

However, for the second interface (mob1s1a1, i.e. active SIM1), the TX/RX rates shown are very small, which looks ok to me, too, because I expect them to be low because of the primary Wifi connection. But why does the previously shown screenshot for “Network > Mobile > Limits > Data Limit > Data used” have the ever increasing “Data used” values for mob1s1a1?

Have a good weekend, and thanks for your help!

Kind regards

Hi 7wells

My rut241 was doing exactly the same. I wrote a post about it but didn’t get any replies.

It now appears to be working as intended. I think in the settings for the WiFi wan interface in failover I set the WiFi wan to flush the other connections when connected, the others being left blank. That seems to have done the trick!

Thank you very much for sharing your settings and information! :heart: Have you set anything about flushing for the other interfaces that you use besides WiFi?

I had nothing set up about flushing for any interface, but now I have set flushing to “connected” (only) for my WiFi interface (i.e. RUTX11 <=> other router). I will check and see in the coming days if this helps. :grinning:

Flushing was just set for the connection (WiFi wan) that I wanted to take priority, with the others left blank. Initially it didn’t seem to be working, but it is now. Maybe after a few reboots :thinking:. The only other change I made previous to that was to give the rut241 a static address on the WiFi wan primary connection, but I can’t see how that would’ve made it work properly.

Hope you get it sorted. I seemed to mess around for days with mine, when it really really shouldn’t take that :joy:

Unfortunately, the new setting has not changed anything, i.e. there was again an upload of approx. 700 MB via mob1s1a1 (SIM1), despite the WiFi connection with my other router.

The high upload is due to nightly backups of my Home Assistant via RUTX11 to my other router. Of course, I do not want to spend on my mobile data plan when I have a WiFi connection.

I wonder what else I could investigate and change.

I should add that the WiFi connection between my RUTX11 and my other router goes over WireGuard, but that should not matter.

Do all devices connected to the rut11x use the mobile data connection? With mine it seemed to be mobile phones. I wondered whether because the WiFi wan and the rut241 had to use the same wireless channel that had something to do with it. Do you have seperate dhcp ranges set up?

Mine did just suddenly start working. I put it down to the flushing setting, which was the last thing I altered. Previous to that I was switching the mobile connection off when WiFi was in range. Not ideal!

Only one device (a Raspberry Pi) is connected via Ethernet cable to a LAN port of my RUTX11, and there are no further devices connected - neither via Ethernet, nor via WiFi. Except, if course, that my RUTX11 is connected via WiFi with my other router, and this connection is very stable.

Just a thought when I was thinking about the set up. This is my default failover rule. I might have altered something in here :blush:

Again I see about 700 MB data upload last night via mob1s1a1 despite an established WiFi bridge between my RUTX11 and my other router. Please find below more screenshots of my current setup. Do you have an idea what is wrong with this?

Hello! I’m still struggling with the same problem, i.e. despite my established and running WiFi connection, which is set as primary route in the failover settings, my RUTX11 prefers to send and receive data via mobile (mob1s1a1). This unnecessarily reduces my mobile data plan, and I would be very glad if you provided me with some suggestions what I could try. Thank you very much! :heart:

Dear Teltonika Team,

Have you seen my additional screenshots etc.? It is a bit frustrating that the RUTX11 uses mobile data all the time, while it has Wifi connection that has prio 1. Thanks for letting me know if you need more information from me! :+1:

PS: After FW update and restart, I observed in the event logs:
WAN (ifWan2) is down, switched to backup WAN (mob1s1a1)

Why does failover let it switch to backup WAN (mob1s1a1), whereas WiFi has a higher priority in the failover settings? At least to me this event message suggests that it switched to mobile (not to WiFi). Why?

Kind regards

This appears to be the same issue I am facing here: Strange WWAN data usage every day at midnight? RUTX11

Dear Teltonika Team,

The problem still persists. Maybe you could provide some more guidance how to set it up correctly. Thank you so much!

Hello,

Sorry for the delayed reply. I would like to review a troubleshooting file. I have sent you a form to fill out, and once completed, I will contact you privately regarding this. Please use “9204” as the ticket ID.

Best regards,

Thank you, I have collected and sent the Troubleshoot file.

Sorry for cross-posting (Strange WWAN data usage every day at midnight? RUTX11 - #10 by 7wells), but in case someone else has a similar problem, they find it here, too.

My router is already on the latest available FW (RUTX_R_00.07.09.3) for several days.

Interestingly, there is a ditch on 29 Sep 2024:

However, the same information in another (status) screen looks differently, i.e. no ditch shown on 29 Sep 2024:

How comes that the “SIM1/Mobile Usage” shows different values compared to “Status/mob1s1a1 traffic”?

I will check the form within due course. Thanks for that, too!

Hello @7wells ,

Please create a separate topic regarding this issue. Thank you!

Best regards,

Maybe I misunderstand something, but why should I create a separate topic? I created this topic myself, and it has not changed, nor do I currently have a new one. Thanks for your help!
