Intermittent connectivity/latency spikes/disconnects

The issue that a few of us are experience (not sure why this particular thread has sharded so much in the forum) is a persistent latency spike between router and satellite. It's been proven - now by multiple users - to happen exactly every single hour. The time might differ (this we're unsure why - could be when it was rebooted or some other process). 

I've myself done extensive testing with multiple devices - and I can say with 100% certainty that without fail, every single hour to the microsecond, you'll get a 2-5 second "spike" in wireless latency from anything connected to the satellite. It's more pronounced in anything with a realtime connection (eg video conferencing, game streaming etc).

I've confirmed it is NOT an ISP issue - I've since switched ISPs and changed connection completely - brand new cable install with full fibre FTTP, new ONT etc etc. Also some of the apps/devices are using internal traffic only.

There appears to be some sort of process that runs, maybe it's some wireless check/sync between router and satellite, or some hw process -only NG knows.
