Configuring LTE interface problem -- RBwAPR-2nD&R11e-LTE

Hello everyone,
this is the first time i try to configure an LTE interface in order to connect to a cellural ISP.

I am using the wAP LTE kit / 4G kit, in which i've inserted a mobile phone SIM card.
I also use this article, as a guide.
https://stevedischer.com/mikrotik-rbwap ... zon-howto/

My problem is that, after configuring APN........

........i no interface is created

Capture.LteInterface.PNG

Also, LTE scanner, doesn't return any result..

Customer claims the product is faulty, and i have to verify if so..
Any help?

Check if USB bus see the device:

/system resource usb print

Check if "ignore-directip-modem: no" in:

/port firmware print

Do you see the lte1 device anytime ? This is a new device from distributor or used ?

And the most important. lte1 interface should show in Interfaces > LTE even if you have bad or not set any think inside APN. The APN not enable lte1 because it's work only when lte1 is exist.

Hey SiB, thanks for the reply:

I got these results:

[admin@MikroTik] > /system resource usb print
 # DEVICE VENDOR                   NAME                   SPEED                  
 0 1-0    Linux 3.3.5 ehci_hcd     RB400 EHCI             480

[admin@MikroTik] > /port firmware print      
              directory: firmware
  ignore-directip-modem: no

Also there is no trace of lte1 anywhere...

And it doesn't show up in "Interfaces -> LTE" too....

Better open device, maybe you have version without modem ?!
Should be like this: https://www.youtube.com/watch?v=uuQgoxGtcnc

but maybe is like this :( ?

It does have a modem inside.. like your first picture.
Suppose that it is faulty indeed? Perhaps customer damaged the device with wrong use of POE or something? It used to work as he says...

Upgrade ROS and boot-firmware to the test version:

[marcin.przysowa@SXTR_LTE6] > /system package update set channel=testing 
[marcin.przysowa@SXTR_LTE6] > /system package update install 
y
# after reboot
[marcin.przysowa@SXTR_LTE6] > /system routerboard upgrade 
y
[marcin.przysowa@SXTR_LTE6] > /system reboot
y

Please power off RB.
Plugout modem (only from mPCIe socket without touching antenna).
Plugin modem in mPCIe slot.
Power On RB.

RB should detect the device at USB.

/system resource usb print

You can do restore default settings

[marcin.przysowa@SXTR_LTE6] > /system reset-configuration skip-backup=yes

Please check the USB settings. This is a stuff by why your ROS can not detect modem. Those one need reboot to activate:

[marcin.przysowa@SXTR_LTE6] > /system routerboard usb print default-config
[marcin.przysowa@SXTR_LTE6] > /system routerboard usb set type=
USB-type-A  mini-PCIe
[marcin.przysowa@SXTR_LTE6] > /system routerboard usb set usb-mode=
automatic  force-host
[marcin.przysowa@SXTR_LTE6] > /port firmware set ignore-directip-modem=
no  yes

You can buy cheap $10 USB WWAN adapter and plugin this modem to other RB or PC to check if will be detected.

Still no result - I think it's damaged.
