What 3rd Party LTE Modems are compatible with the RBwAPR-2nD

I have a RBwAPR-2nD but it came without a modem. I have been trying to find an L11e-LTE, but none seem to be available separately. So I was wondering do I have to use a genuine L11e-LTE, or can I use any 3rd party modems? If so, does anyone have any experience of suggested models that “just worked”.

I have the “reverse” problem. I just purchased the RBwAPR-2nD US version with the R11e-LTE-US modem. Getting past the long story of no major carrier in the US having Mikrotik’s IMEI range in their systems, I was able to get one of the carriers to sell me a pre-paid plan and got a sim for the device.

UGH!

Full disclosure before anyone says “hey stupid, you just…” I have a LOT of Mikrotiks (love them!), but this is my first venture into using cellular as a backup device. Of course my first probably stupid act was to upgrade the software from the 6.40.3 that it shipped with. Could not get an IP address on that version so I upgraded through a couple of versions, eventually even trying 6.44beta20. Can’t even SEE the LTE in DHCP client to try to get it an address. The newer versions mostly see the network and say it is registered (Have to pick 3G, since placing it on auto gets an error because the card doesn’t support GSM). But getting past that, and of course the HORRIBLE technical support of the carrier who cannot seem to understand that there are things other than their “hotspots” or a tablet, I am now in hour 10 or so of playing with this and getting no where.

Probably should have just made a new topic, but it seems to me that the conversation is related since I will gladly chuck the R11e and put something else in if there is something that “just works”.

Ok…so after endless hours messing with it, someone I know who works at AT&T said that the APN has to say “broadband”. Changed it from the default of “internet” to “broadband” and it connects. Someone probably already noted this somewhere and I just didn’t see it, but in the US you need to have the APN say “broadband” for the AT&T network!

Have a look at the list here:

This list will be greatly expanded and improved once ROS7 and it’s far far far far newer kernel is used which will mean a lot more native LTE mode compatibility rather than a USB/Serial port mode and PPP being used.

A few years ago I tried an older Telit LE910 module which worked in PPP mode. I recently tried a much newer model LE910 and had no luck much to my chagrin as it needs to operate in LTE mode. Frickin’ hurry up with ROS7!
