We have been experiencing extreme periods of outages where our LTE Home Internet Gateway disconnects from cellular service and will not reconnect. In some cases it bounces back and forth from connected to disconnected repeatedly but will not remain connected more than a few seconds at a time.
We have a 5G router and during periods of LTE Home Internet outage our cell phones usually stay connected with 3 bars of 5G service.
The router typically is in a Tech Status of "5G_NSA", but it sometimes appears to to try to fall back to 4G LTE service unsuccessfully.
I have not been able to find any way to access the device logs. The outages do appear to be more frequent and severe in the evenings and on weekends.
The Internet Gateway software version is 214322 applied on 11/29/2021.
