How to use RB411U and Sierra Wireless Modem 4G LTE MC8092

Hardware MikroTik hardware general
1

Scenario: RB411U + FW 5.22 + 4G LTE Card MC8092 (Sierra Wireless)
The LTE Info gives some error (see image belove)
Is the 4G LTE Card MC8092 supported?

Non penso funzioni la MC8092 in italia, tant’è che la riconosce ma ti da errore di segnale.

Da sito Sierra:

MC8092: Dual-band UMTS/HSPA+ connectivity,
dual-band diversity (900/2100 MHz)

Non è LTE, la lte mi pare sia la MC77XX

Ma il router lo vede come interfaccia LTE.

most likely those AT commands are not supported by this card that is why you have those ERROR values.
enable the lte1 interface and then check if it connects fine. If yes then add a dhcp-client on that lte1 interface.
For debugging enable async,debug logging.

Hi,

I have the MC7710 from Sierra Wireless and trying to make this card work on the RB411U
and I came across the same as you see, but if you query the modem without the question
mark it responds.. My modem is not registered to any network yet, so I do not know it the
modem responds differently when online.

From my terminal you see the difference:


[admin@MikroTik] > /system serial-terminal usb2 channel=3

[Ctrl-A is the prefix key]

AT
OK
AT+CSQ?
+CME ERROR: operation not allowed
AT+CSQ
+CSQ: 99,99

OK

The modem MC8092 is not 4G LTE.

Ipse dixit.
