WE826-T2 and EM7455, not connecting
Posted: Sun Mar 24, 2019 8:44 pm
I'm terribly new so please forgive any mistakes and information left out. I have a WE826-T2 and an EM7455 modem. I'm using a sim card from my company laptop for testing and I was able to get it to come up and connect. It was terribly slow, so I tried to switch it to MBIM mode usning the following:
Afterward, the modem will no longer connect. I tried to set it back to QMI mode and nothing has helped. I reflashed my router and started all over again multiple times, to no avail. Here's the modem debug log, please excuse any copy and pasting errors, I tried to catch it as it scrolled through and i'm not sure if I got it all.
I tried resetting the modem multiple times but i have not been able to get it to reset again. My apn is vzwinternet. The modem is seen, however it fails to connect. My sim seems to be ok as when I query it I get the phone number back. If you need any additional information, please let me know.
Thanks,
Mike
