Can't connect with mobile (RUT260)

[stianj]

Hi!

Bought a RUT260 to use in our cabin to replace a Huawei B535 that broke because of too high voltage… At work I use a lot of different Advantech gear, but was really intrigued by the price of Teltonika, and the features looks to be on par with Advantech. Received it two days ago, just in time for bringing it to the cabin during Easter holidays.

But I’m unable to get it to work… Have tried with three different sim-cards (not that I really thought it would matter) - all of the unfortunately the same carrier (Telenor).

This screenshot shows the status:

I have tried with manually entering both APN and even the operator info - but does not make any difference.

I’m hoping I have received a defective unit, because I can’t for the life of me understood what could possibly else be wrong here…

Would greatly appreciate some feedback here before I RMA it…

Regards,
Stian

Some additional info…

Hi, did you tried to use empty APN?

[ReDiculum]

Since RSSI has no value, it seems that even the antennas do not have a signal. Maybe check first the SMA antennas, especially their small pin in the middle if it’s not broken

[iBoucher]

There won’t be any RSSI value if you are not connected on any base station. It doesn’t mean that antennas are broken.

Hi! Sorry for the late reply - Easter took all my time

It’s not the antenna connector(s), I’m also using an external antenna when at the cabin. But I have also (of course) tried with the antennas that come with the router. And while the reception at the cabin is not great, I have also tried it at home where reception is great.

I have tried to use empty APN as well. Here is system log when trying:

When I google the “GSM error” log message, I get some hits from Teltonika forum with a few users with similar problems, but not a solution anywhere…

Guess RMA is the next step here…

Is this expected behaviour?

root@RUT260:~# gsmctl -A AT+COPS=?
+CME ERROR: operation not allowed

Hello,

Just to clarify, what APN was tested on this device?. According to their site (Vad har Telenor för APN-inställningar? - Telenor Privat) the correct APN parameters to use would be:

• APN: services.telenor.se

• Authentication type: None

If these don’t work, could you test the SIM card in your mobile phone to make sure it’s activated and working? Since in your provided screenshot the router isn’t even registered to an operator, it could be that the operator denies the router from joining.
If the suggested APN was tested, we may need some additional information. Let me know if that’s needed and I will send you a form to fill out to get in contact with us privately.

Best regards,

[stianj]

Hi! Thank you for your answer!

Telenor Norway you can use APN “internet” and “telenor.smart” at least (probably more). I’ve tested both, and no difference.

But I have one question, when I’m trying to scan for operators, I don’t get anything - I should get results even with no/wrong APN?

The sim cards are good. I have tried three different ones. All of them have been used just before and just after.

Would be very happy to provide more information privately!

Regards,
Stian

Hello,

Even if no SIM is inserted, you should see the operators when you perform a scan. Could you make sure you have the correct antennas screwed into the MOBILE SMA ports? It’s possible to screw WiFi antennas into LTE ports.
If that’s not the case, does the area that you are in have a good coverage? Would it be possible to test the device in a different location?

Best regards,

[stianj]

Hi again.

I just get “Failed to get scan results” when performing a manual “scan for operators”…

I’m 110% sure I did not mix the antennas. I have also tried with external antenna with SMA connectors (not RP-SMA).

The area where I tested it first have quite bad reception (but not none at all, we have connection on phones, just not great), that is where I had the external antenna. But I first tested with the antennas that came with the router. I have later tested the router in two other areas with very good reception. The result is always the same.

So I guess RMA is the way now?

Regards,
Stian

Hello,

If you haven’t returned the device, could you try performing an operator scan without a SIM card inserted?
If that gives the same result, then it’s likely that RMA will be needed for this device.

Best regards,

[stianj]

Hi!

Sorry, that’s a no-go:

Can’t scan without sim-card it says…

(The RMA is approved, I just hadn’t sent it yet).

Stian
