We see that LTE was added to interfaces and that in 5.10 the port firmware command was added to support GOBI 2000.
Does this mean that support for GOBI 3000 (Sierra Wireless MC7750, MC7780 and Novatel Expedite E362 and E371) is close? What about USB devices too?
Very excited if this is true…please tell us more.
currently we have added only this LTE card for the LTE mode in v5.12:
BandRich BandLuxe C501
If the other cards is using the same driver as this one then we could try to add support for them. Contact support@mikrotik.com with the support output file attached and remote access details to the unit for debugging to check if it is possible to add support or not.
in addition to what uldis said, this is the driver we will use in v5.12:
*) lte - new interface type for LTE modems, currently modems utilizing
cdc_ether driver should work with this release;
if your other card works with the cdc_ether driver, we can try to add support for it.
It looks like Bandrich has a variety of USB and miniPCIe modules that are in the same “500” family and based on MDM9200 Gobi 4000 chips. There are flavors for almost all combinations of EvDO, GSM, HSPA, etc.
In particular we would be interested in the B13 version which is the C506 or M506. It is unclear from their literature if the M50x modules are USB only or full implementation of miniPCIe. We have requested data sheets.
So if the cards support EvDO and LTE B13 and use the cdc_ether driver, then the next question would be about roaming. Verizon, for instance, uses a modified eHDR authentication scheme which allows them to interoperate EvDO and LTE using the same client authentication system. This is a departure from standard LTE authentication. Does anyone have any idea about how to handle this in MT system?
Verizon does not make it easy. On Windows and Macintosh they actual have a user app (VZ Access Manager and windows driver) that swaps the EEPROM around when roaming between 3G and 4G, at least with the Pantech UML290 or the Novatel 551 that is how they do it. It completely disrupts communication when roaming. We have been locking modems to either 3G or 4G on a windows PC before installing to a MT based router. Not exactly what the customer wants, since the router cannot roam between 3G and 4G. We are looking for something that will work with MT and allow roaming between 3G and 4G. This Bandrich product line looks pretty good, but will is solve our issues?
it has built in ability to switch between 3G and 4G. in the LTE menu you will be able to set ‘preferred network type’. also it will fall back to 3G if there is no 4G
We have confirmed with Verizon that Bandrich modems are not approved for use on their network and they will not give you a SIM and approval to operate their modems.
We spoke with Bandrich and they have not been successful in getting their devices approved and are not even trying.
So, does anyone have an ideas on other LTE modems that will function similarly allowing switching from 4G to 3G and back on Verizon?
This is getting to critical point for our customers.
When will 5.12 ship? Will it include full support for LTE modems?
you can get a pre-release by emailing support, but as you said youself, if you can’t use Bandrich, there is no use
We have a major project that requires 4G LTE over Verizon in USA. There are only four modem options:
Cannot use Bandrich. Verizon will not be authorizing this modem.
The bottom line is that we have to support Gobi 3000 in order to work with Verizon LTE. We want to use MT, ROS and MIPS AR71xx processors for this, but the current support for LTE is limited to cdc ethernet drivers that are not compatible with Qualcomm management interface which runs on its own USB endpoint.
Ideally we need to support the Pantech UML290, since that is what we have used so far, just locking them to EVDO mode.
The Pantech has the following layout:
0 (2/2/1): CDC-ACM for AT commands
1 (10/0/0): CDC-DATA for interface 0
2 (ff/ff/ff): Qualcomm DIAG
3 (ff/fd/ff): NMEA
4 (ff/fe/ff): Pantech WMC
5 (ff/f0/ff): RMNET/QMI port
A team of developers has been working on patches to the cdc_wdm module of the Linux USB drivers in the latest kernel. This driver is part of the NEXT test release of kernel. They are very close to having this all working in linux (may already be working, but they need to test). Then all that needs to be developed is the user space application to manage it. What I was hoping was that MT could make this part of 5.13 release and grab the code from kernel driver, add some command fields to the PPP client dialog and get GOBI and in particular the UML290 supported. This will open up a huge market opportunity.
Assuming that this won’t happen we are also working on bringing this capability into OpenWRT and then putting that onto our RBs. We really don’t want to do that. It is a support nightmare, but we have to do something.
We can provide some support towards getting this done such as documentation. See attached.
MT, is this possible?

Clearly this is of interest as 891 views in one day…
MT, any response
I also, now have the option of using a LTE USB devices (Verizon) on projects now and agree this should be addressed as soon as possible.
email mikrotik. mikrotik staff is not following all forum posts.
If no one from MT is watching, then how did you know to respond?
What do I need to email beyond all of the information conveyed here? Happy to provide whatever is required to get the driver done.
Obviously nearly a thousand other folks are interested in the outcome.
we need a supout.rif file from the device with the specific modem, and we will see if we can add support for it.
supout.rif was sent
I sent the supout.rif two days ago and have not heard anything. No acknowledgement, no trouble ticket, nothing. Can someone at MT at least let me know you received it? Sent a follow up email that was not responded to either.
Thanks
you should receive at least automated replies with ticket numbers
Nope, nothing. I do get notices of postings to the forum, but nothing from support.
we haven’t received any emails to support@mikrotik.com from your email address. Could you try to send it from different email address?
Can you please check your spam filters and block lists for my domain cafedot.com. I have no issues sending or receiving mail to others.
I sent the support request from yahoo mail. Ticket#2012020366000461

Why can’t you use the Sierra Wireless module? I am interested in this post as well. I would like to see if I could use the Sierra module to connect an IP camera up to the router.
