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?

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