generic MC7455 won't connect to network
Posted: Tue Nov 30, 2021 3:24 pm
Ok, have a mc7455 that was out of a BEC technologies LTE router. Generic firmware.
I've updated the card to latest f/w.
The card works in QMI mode in the BEC router fine (mbim it will not)
Put mc7455 in my rooter router and changed to mbim mode:
OK
Sim card and imei shows up fine. I put a EC25-AF (both qmi and mbim mode) in and it connects within 30 seconds.
