I saw some threads about the same issue, but none are resolutive.
I have EP06ELAR03A08M4G modem (Quectel) pre-installed in the AP1300.
After updating to 4.3.7 the connection sometimes drops for hours and then comes back.
This is annoying, since I control this modem remotely from a different city. The modem only has LTE connection (no backup) and it is used to provide internet access to IoT devices and IP cams for survelliance.
I tried set QCM, QMI, different APN settings but the issue is still the same.
Any chance to stabilize it ? It’s a problem for me to get it back to 3.x for now…since I live 500 miles away from that city.
Any hint is appreciated.
Thanks a lot for your help,
