RUTM50- Connection Stage Unknown

Hello,

I have a RUTM50 router that is connected through AT&T Cellular 5g. I continue to get a Connection stage unknown. I have updated the firmware and I have checked with AT&T. All setting show correctly. Has anyone run into this? Is this an issue with the router or the service

Hello,

From your screenshot, I see that your device has firmware version 7.06.8. Could you please confirm whether you have tried upgrading it to version 7.11.1? If you have, does the issue still persist?

You can download the firmware image from this link: RUTM50 Firmware Downloads.

Best regards,

Yes I have factory rest the router and run the latest firmware update.

RUT_R00.7.11.1_WEBUI.bin

After the update issues remained.

Hello,

Could you please specify the version of the internal modem on your device? You can check it by navigating to System → Firmware → Update Firmware.

If an update is available for the internal modem, please proceed with the update.

Best regards,

I’m having a similar problem. I have two RUTM50s on AT&T Wireless Enterprise in the US. I upgraded to 7.11.4 recently and my mobile connection began dropping every two hours or so, and it requires a reboot to connect again. This was around the time I made some other config changes, so I can’t say for sure whether the issue is related to new FW. The indications are the same on both routers.

Hello @smb77 ,

Could you please try the steps outlined here: RUT240 Mobile connection drops every 2 hours - #12 by Marija and let me know if they help resolve the issue you are experiencing?

Best regards,

Hi Marija,
Explicitly disabling dhcp on mob1s1a1 resolved the issue. Thank you !
I do use these devices in an enterprise environment - for my records, can you elaborate on what’s causing mob1s1a1 to improperly run the dhcp client? Is it a FW bug?
Thanks,
Steve
