LtAP mini series LTE missing.

Mikrotik Problem.PNG
Shown in the attached picture is the way I normally set up and the problem I am having with the LtAP mini series. I have set up a few of these with no problems. But have gotten 2 now with this same issue. As shown in the picture, after inserting the sim card I go to 1.Interface 2. LTE 3. LTP APNs and then create the APN for the provider. The 2 units I cannot get to work do not show anything in the number 4 area on the picture. Where as the others that I have set up have a “LTE” item on that line. I had to install the one I had that was working, and the new one I got is doing the same thing. Please help. I hope this is just a quick setting change.

side note. I have tried changing the sim slot to the top slot, and changing it in the routerboard setting, no luck. I try to set the APN manually in the quick settings, no luck. I am at a lost of what to do.

Apart from inserting the SIM, did you also insert the LTE modem itself in the miniPCIe slot inside the case?

The LtAP mini can be purchased without a modem or as a kit, with a modem. Depends which one you ordered.

I did not know there were 2 different models. I only inserted the sim. It is supposed to be a “kit”. It is the “Mikrotik LtAP mini LTE kit small weatherproof wireless access point with built in cellular modem”. That’s the amazon description. I have gotten about 4 or 5 of this same model and about half have the same problem.

Why you buy device not from distributor?
btw, this amazon auction should give you a modem r11e-LTE-US.

Check this:

Witchout r11e-* device means LtAP mini without modem.
You can open box and check the modem exist or not.

Open it up and see if there is a modem in the slot. There is no warranty sticker, it’s easy to open.

I think it has one. Please see attached picture to make sure I am right.

Run WinBox > New Terminal or just connect via ssh/telnet/romon/mac-telnet and share results from:

/system resource usb print detail
/system resource irq print where users~"usb"
/system routerboard modem print
/interface lte print
/interface lte export

Here you go.

At your place I will use warranty and turned this device.
Modem should be works out-of-box and only APN can not give automatical connectivity with internet but the devices is not work properly for you !.


But you can do few commands only

Reset to FactorySetting by:

/system reset-configuration skip-backup=yes no-defaults=no

or

This yes or no enable/disable detection modem as PPP or LTE device - perhaps this should be change to opposite. I have got the NO value. You can check the check box in WinBox of this.

port firmware set ignore-directip-modem=no
system reboot

or

Type of working the additional USB BUS but this is never changed until someone (previous user of device) not try use other modem etc. This is last hope option.

system routerboard usb set type=USB-type-A
system reboot

or

system routerboard usb set type=mini-PCIe
system reboot

If all those not change the discovery of LTE device then sorry.
Use warranty from distributor.

btw, You can buy $10 WWAN USB adapter and plugin this momem into adapter and use it at other MikroTik to checking purpose but this is just additional option.
I hope you have warranty because your device not work in normal proper way.

Good Luck

The LTE modem was not detected until LtAP mini switched power from micro-USB to power supply 24V 0.8A

13

The modem portion seems to be missing in ROS7.6, not sure what version it was lost in. I’m trying to figure this out so I can use USB Android Tethering for a special application via “set ignore-directip-modem=yes” and I’m not getting anywhere because this is no longer available and I can’t seem to find anything on where it was moved to or if this feature was removed altogether.

What.., Tethering is not about “not detect lte module inside”. The ignore-directip-modem is now in interface > lte tab > modem button > mode but maybe just read a official MikroTik documentation !
