Mikrotik 5G R17 ax S53UG+ italy lte issues

RouterOS
1

Hi, i just purchased this model from mikrotik and i think there are some heavy issues on LTE interface. I’ve tried everything from downgrading / upgrading RouterOS, following docs and AI tips on how to setup a proper mobile sim installation, but still can’t get this router to connect to the internet.

I’m using a very mobile sim (WIND MVNO) from Italy

Symptoms:

commands like this one gets strange answers from the system..

firmware-upgrade lte1 upgrade=yes failure: Firmware update is not supported on this device!

also i get answers like “eSIM not supported!” while trying to setup an eSIM on this device.

At the moment im using 7.22.rc3 out of desperation but tried 7.20.7 longterm, 7.21.3 stable… same results!

is there any way to manually force upgrade firmware on this particular modem (maybe firmware/bios of the modem got corrupted?)

Model:

S53UG+5HaxD2HaxD-TC&RG650E-EU

Upgrading firmware has nothing to do with setting up a LTE connection (via sim or esim).

You normally first have it working, and only later if needed you upgrade the firmware.

Are you having a "modem failed" on lte1?

Like here?:

RG650E-EU - Modem Failed

Using that command

interface/lte set lte1 modem-init="AT+QCFG=?"

on the link you provided doesn’t get any bad results (no output on the screen)

Note: before getting your reply i just did a NetInstall of RouterOS 7.20.8 Long Term (first, installing routerOS alone with netinstall then adding the 7.20.8 LT wifi-qcom package afterwards.)

tried forcing “internet.it” APN (correct apn for very mobile ISP) (pic provided) but no luck.

trying ping 8.8.8.8 gets

SEQ HOST SIZE TTL TIME STATUS
0 192.168.224.1 84 64 633us net unreachable

4 8.8.8.8 timeout

Sometimes there is a disalignment between GUI and terminal with "use network APN".

Open terminal and run in it:
/interface lte apn export

you should get:
/interface lte apn
add apn=internet.it use-network-apn=no

I got this output. Hope there is some advanced user from italy of this particular device that can help me sort things out… the settings are mostly default configuration, i modified only LTE settings and wi-fi (and system clock/date)

maybe this is the cause of the issue? Why init modem with modem config query command?

BTW I have same device, no issues, but not in Italy, I think "modem failed" error is not related to country.

The default for use-network-apn is "yes", so if it doesn't show it is still "yes".

Then issue:
/interface lte apn
set [find name="very mobile"] use-network-apn=no

And try again with:
/interface lte apn export

the export should contain the "use-network-apn=no"

Try also cycling the interface, i.e.:

/interface lte disable lte1
:delay 3s
/interface lte enable lte1

i have tried your commands with no luck. tried to troubleshoot with the help of gemini AI and basically came to the conclusion the modem firmware could be broken or the modem not functioning properly.. or a software incompatibility with this specific modem version

Ah, well, if gemini concluded that, It Is settled.
