I plugged huawei E3372 with Airtel India 4G sim on USB port 2, This dongle works perfectly on my PC and based on cisco recommendation the dongle firmware is correct.
I tried both in Auto and manual configuration but the connection doesnt works.

There is no info in the logs as to why connection can't be established.

Pls. help, attached are some screenshots.

Follow this guide. You gotta reflash the firmware to stick mode for CIsco to recognize it. I have an RV345 and the same dongle.

Anyone know if this bug is fixed in the new 1.0.03.24 software?
