RBM11G and Fibocom NL952-EAU modem randomly changing USB driver

Sat May 13, 2023 9:57 am

I'm testing out a combination of an RBM11G running 7.9 stable and Fibocom NL952-EAU modem.
Under normal circumstances, the resources look like the below. The modem is recognised as a USB Fibocom modem.

However after a seemingly random period of time, the LTE interface disappears.
Checking resources sees that the modem driver has changed from Fibocom modem to Qualcomm bulk.

What on earth is going on there?

@normis, Mikrotik may wish to investigate this?

This module is available in the Three Sercomm router, currently available for £30 on eBay so it's a particularly high performance module being sold particularly cheap with ROS support and there is apparently an issue with compatibility.

Likely going to be more complaints as this is being documented over on IspReview.

I'm hoping a contact at Fibocom will provide latest firmware.

Currently at, 19603.7000.00.04.01.04, suspect it's the same for all modules coming out of those routers.

Probably not.
MikroTik can't buy all the hardware in the world to test it and make itself compatible,
rather the opposite,
contact "Fibocom" to solve the problem, and see what they answer.

[…] then Mikrotik should remove it from the supported peripherals […]
https://help.mikrotik.com/docs/display/ROS/Peripherals
It is clearly stated:
MBIM driver. Revision: 19600.7000.00.04.01.05
If you have a different firmware version, why would MikroTik remove it from the list?
It is up to you to use the same firmware version,
and at the same time MikroTik cannot follow all firmware changes of every listed manufacturer...
Indeed, it should be noted that it is correct to indicate the compatible number...

Wrong example:
Motherboard makers are interested in running only TWO manufacturers' processors,
MikroTik doesn't care about being compatible with all the peripherals on the market,
there aren't just two like Intel and AMD, there's just a myriad of other manufacturers.
It is the manufacturers of the other peripherals who (if interested) have to deal with compatibility.

Also…they make modems themselves, so how do you think they care about running products made by other companies?
If you want a compatible and supported model, buy a mikrotik one.

Re: RBM11G and Fibocom NL952-EAU modem randomly changing USB driver

[…]
I purchased the Mikrotik product based on the fact it states the module is supported.
If Mikrotik determines that actually, it isn't, then that's fraud (I believe) and sale of goods by misrepresentation and opens Mikrotik up to civil lawsuits.
[…]
Talking about fraud and suing MikroTik really shows your poor understanding of things.
If you do not read first, it's not MikroTik's fault.
Before buying the module, did you ask the dealer what is the installed firmware version?
Of course not, and going to court because of your omission is certainly not as smart as buying a device without first checking if it is compatible.
MikroTik was clear, that device with that versions.
It's your failure if you didn't make sure before buying the product it was compatible or not.

[…] minor differences in firmware revisions […]
Do you have the source code of both firmwares to compare?
You don't know at all what changes inside (me neither of course).
You're just writing at random because for your, and only yours, mistake...

OFFTOPIC:
It's like Ferrari refusing to work on a car because a headlight bulb isn't OEM.
But did you know that, in practice, it really is like this?
You buy the car, but Ferrari repairs it only and exclusively if all things are Ferrari certified...



So in short:
1) You didn't make sure beforehand if the version is compatible
2) It is not the same firmware version
3) If it were the same firmware version, however MikroTik is not responsible for the bugs contained therein
4) The modem works at first, but then randomly stops, so if it works at first, how do you tell it's a MikroTik problem?
5) It could be a firmware change in the modem causing the random problems
6) You have not contacted the modem manufacturer
7) If the modem has firmware problems, it is not MikroTik that is required to solve them
8) MikroTik is not required to try all the peripherals on the market, and then of each peripheral each firmware, to verify its compatibility
9) MikroTik produces modems, which it supports.
10) You claim support for hardware produced by others, from a competitor company that also produces modems.

You could have avoided all this if you bought a MikroTik modem directly, instead of buying it from a competing company.
Nothing more, nothing less.

Just found out you were made up to a moderator here and was swiftly demoted.

There's even a thread online discussing your antics. Genuinely not surprised.

I almost 'lol'd but decided it wasn't worth the effort.

Nevermind. Oh and I had already been in contact with Fibocom who stated its down to Mikrotik whether their hardware supports Fibocom modules so go figure.

Nonetheless, Fibocom sent me hardware manual, AT commands and firmware for the module and it seems to be stable(r) now.

And as I've already stated - I've spoken to Fibocom who said it's up to Mikrotik whether their board support Fibocom hardware - an entirely reasonable claim and expectation.
I've simply asked for support on a product combination that Mikrotik said is compatible, irrespective of the firmware revisions - it's a fact they get updated with new features/security updates etc and it is a reasonable expectation that where updates are concerned, compatibility is retained. It's a basic fundamental of any hardware owner that has software control unless the product is EOL in which case I would understand a lack of support. A fact that you clearly have no comprehension of.

At the end of the day, It's down to Mikrotik whether they offer that support - and they are, via Email - so thanks to Mikrotik support for responding.

You don't speak for Mikrotik and you clearly really shouldn't do either as it has already, clearly, backfired for you and I feel sorry for you if the only contribution you feel you are able to add is to purposefully antagonise.

If there are any Mikrotik Moderators reading this, I would be quite happy for the thread to be deleted as I have no intention to persue this fruitless venture with this halfwit any further and support is being provided elsewhere and this thead services nothing of use currently.

Thanks!

Never wrote that I work for MikroTik, and I've never worked for them,
and in any case,
the fact that you have deleted all the post where you want sue MikroTik because the product, which you have not checked in advance, is not compatible,
indicate a lot about you without the need for me to invent things or search you on reddit,
and then you talk about personal offenses when you are the first to provoke, over and over again?

Have a nice day.

@dazmatic

Do you have the firmware that Fibocom provided you, as I have this modem and would like to see if I have the same issue.

Never said I wanted to sue - merely indicated that it's a risky business to state something is supported and then refuse support which you implied they would due to minor differences in firmware which would open them up to civil claims.

I deleted the posts because they're not relevant and a waste of all others time to filter through. You don't seem to be able to get the point and drop it.

I'm also trying to indicate that you should stop commenting on behalf of Mikrotik.

And I never mentioned Reddit - paranoid much?

@hecatae - where did you source your modem from? I'm aware of at least one other on another forum who's having a similar issue.

I'm not keen on sharing the firmware just yet, not least while I'm trying to look into what's happening but I'll try and keep this thread updated for future reference, if nothing else.

Mine switched to 'download mode' again today but caught it in time to export a support file, it's up on a support ticket with Mikrotik now so hopefully they'll look into it.

No, if you follow the forum, often spammer copy & paste reddit post of some years ago for add later spam links.
Not your case, of course.

Never said I wanted to sue
Of course, in fact you deleted the post, so you never wrote it.
Right reasoning.

I'm also trying to indicate that you should stop commenting on behalf of Mikrotik.
I didn't delete my posts, unlike you.
Where is it written that I would comment on behalf of MikroTIk?

Do you have to invent another nonsense every time you answer?
You are just a waste of time.

So, speaking to Mikrotik support they have suggested that the module is crashing and dropping to a (memory?) dump mode

Checking with AT+DUMPEN? shows that the dump mode is set to 1 and so the device will sit there waiting for a dump transfer.

Setting AT+DUMPEN=0 will disable the dump mode and allow the module to reboot and recover so I've been informed.

/interface/lte/at-chat lte1 input="AT+DUMPEN=0"

It's a temporary fix that will enable the module to continue to be used with minor interruptions. I'm conversing with Fibocom and Mikrotik for a fix.

It was honestly too easy 🙃


Anyway, quick update, the individual in Mikrotik support who has been helping is the same that Fibocom has been speaking too, so I'm hopeful for a resolution or at least a way forward.

I think next step is to try and get a dump of the logs from the module but that's not documented so I'm relying on them for that.
