MR1100-100NAS no B20, NO SCC Carrier aggregation

Hello,
I am using the MR1100-100NAS device.
Firmware:
MR1100-100NAS_23113828_NTG9x50C_12.05.05.00_00_GenericNA_01.02 (newest).

The device does not support the B20 frequency, the aggregation is also not working -

AT!GSTATUS? command shows PCC only, no Secondary Component Carriers (SCC).

Of course, carrier aggregation is supported by other devices in this place so it's the problem with NETGEAR's device.

Reset of the device does nothing in this case.
NETGEAR's technical department, please help me to solve the problem.

Also adding second screenshot showing aggregation that just doesn't work.

What are the other bands/cells what you miss ?

Re: MR1100-100NAS no B20, NO SCC Carrier aggregation

it seems this unit does not support B20,  from the first screen capture, you might need to check on specsheet from the vendor for 100NAS. As for aggregation, it would be depending on the carrier if they do support aggregation.

Re: MR1100-100NAS no B20, NO SCC Carrier aggregation

Thank You for your answers.
B1+B3+B7 should be aggregated and it's fully supported by BTS (checked with few other devices with the same SIM) - again, it's not problem with SIM, BTS or ISP.
None of aggregation is working, 2CA too.
NETGEAR'S Support, could You please tell me if aggregation on my device can be somehow blocked?
MR1100-100NAS should support also B20, it's officially confirmed by NETGEAR - I've checked and it's not so it seems to be an critical bug in modem's firmware.
Without aggregation the device is almost useless in normal conditions.

Re: MR1100-100NAS no B20, NO SCC Carrier aggregation

From the screen capture you provided, current firmware does not support B20, it might be limited by the firmware, need to wait for Netgear's official explanation if that was done in purpose or can be added in later firmware.

As for aggregation, when I was with Auto in "Band Region" option, it would not do aggregation all the time, depends on signal of what area I was staying. You might need to enable LTE Band lock function to force M1 to just land on the Bands you specified and then aggregation might be working.

from the datasheet, https://www.netgear.com/images/datasheet/mobile/MR1100_100NAS.pdf, it shows no B20 is supported, FYI.

Re: MR1100-100NAS no B20, NO SCC Carrier aggregation

Thank you for your response.
In fact, the document you sent informs that 100NAS has no support for B20.
However, when I bought this device I was guided by this official information, which seems to be more up to date - it's from the end of 2018 and it clearly states the support for B20:
https://kb.netgear.com/000060410/What-cellular-bands-are-supported-by-MR1100-Nighthawk-M1-Mobile-Rou...

 

It is simply pathetic that the company can not clearly determine what it produces and one of the information is misleading!

 

Unfortunately, forcing band lock with AT! BAND command did not work - again, only one frequency works at once and I am sure the command is typing correctly, for example for B1+B3+B7 aggregation:

AT!BAND=03,"LTE B1+B3+B7",0,45

 

NETGEAR SUPPORT, You are last hope for this device and for my respect for NETGEAR company.

Re: MR1100-100NAS no B20, NO SCC Carrier aggregation

Yes, you are right about the band support information, the one I have found might be out of dated, so updated firmware is required for your 100NAS to support B20. As for aggregation, I am having similar setting as you did, the aggregation is not done always, it was started with no aggregation but sometime after the aggregation is turned on, I noticed that 4g/4g+ is changed right next to signal bar on M1’s panel, might not reflect to what you are running into though.

Re: MR1100-100NAS no B20, NO SCC Carrier aggregation

Of course, I know that the aggregation is not done always because it depends of BTS.

But it's never done in my case. It's somehow locked.

 

@Blanca_O, could You please help to make my device usable?

Hi FCB90,
I'll maybe get a mr1100, but I'm worried about the b20,
Can you confirm that a firmware update resolved your problem?

Re: MR1100-100NAS no B20, NO SCC Carrier aggregation

Of course, NETGEAR's support did nothing in this case.

It's my first and last device from this company.

Back to the topic, I've exchanged my device to new one (both from ATT) and still, bands aggregation doesn't work.

It seems it's problem with ATT firmware (tried few versions, newest one too and none has worked properly).

Re: MR1100-100NAS no B20, NO SCC Carrier aggregation

Also B20 is not supported on both 1A1NAS and 2A1NAS from ATT.

NETGEAR lies to tell you that B20 is supported on these devices:
