My LTE home WAN connection drops at least once per day. I use it as a backup WAN with auto failover so the impact is negligible but it is not normal. I see other people on 5G experiencing the same thing with no fix in sight. I also can't update the firmware due to error that lots of others also get. There is no way I could rely on this as the only Internet connection to my home. Typically drops are only for a couple of minutes but they have been occasionally several hours. The only reason I know it is happening is by getting a notification from my Firewalla router where I have setup multiple WAN support.
