Hub 3 in modem mode is suffering internet outage every night for last week or so. Roughly same time between midnight and 1am.
TV remains on throughout and WiFi signal from Asus Router is fine, it's purely a loss of internet to the Hub 3. Green double arrow flashing for a bit then base light flashes green as though trying to reboot and cycles like this for the period of the outage.
Off for around an hour then seems to re-establish connection itself. Power cycle has no effect.
Online help identified an issue and progressed to engineer visit but would be good to avoid that if possible.
Kit ran as is in previous property for a few weeks then moved house. Worked ok for first couple of weeks then dropping every night, so the move is probably unrelated.
