I am trying to locate the latest firmware for the Avnet/AT&T WNC 14A2A. I see the update manual referncing NQ_MPSS_IMA3_v10.58.174043 (LTE-M) and CM_MPSS_M14A2A_v11.50.164451 (LTE). But I also found a refernce to CM_MPSS_M14A2A_v11.50.171541. I dont know if 171541 is for LTE-M or LTE.
Is there a central site for latest firmware?
I am using 174043 to connect LTE-M. My issue in a strong signal area sometimes it will connect fine.
At other times it will not connect at all .
. I have tried hardware powercycle of the module that does not help. I have checked and verified the SIM status and the APN.
I have verified that the LTE-M device itself is not connecting - it is not an issue of the raspberry pi getting the IP address.
Thanks for your help.
