Hello,

I’m having trouble using 2 mPCI Sierra 7710 LTE modems. 1 modem is working properly, and the second is not responding. The system appeared 1 lte interface, and the second modem when trying to get information about the network displays an error - “Modem didn’t responding”. RouterOS 6.18

How can i fix it?

Hi tubus!

The problem:

[admin@MikroTik] > /interface lte print 
Flags: X - disabled, R - running 
 0 X  name="lte1" mtu=1500 mac-address=82:26:30:13:01:07 modem-init="ATDT" 
      network-mode=auto authentication=chap 

[admin@MikroTik] > /system routerboard usb print 
  type: USB-type-A

ITS SOLVED!

[admin@MikroTik] > /system routerboard usb set type=mini-PCIe 
[admin@MikroTik] > /interface lte print                       
Flags: X - disabled, R - running 
 0 X  name="lte1" mtu=1500 mac-address=82:26:30:13:01:07 modem-init="ATDT" 
      network-mode=auto authentication=chap 

 1    name="lte2" mtu=1500 mac-address=36:A3:1B:FF:02:07 network-mode=auto 
      authentication=chap

I tried to transfer mode. It does not solve the problem. Second LTE interface does not appear.

Did you put the cards into slots correctly? Did you wrap screws in the slots?
