Perhaps you could post the modem stats (upstream/downstream & network logs). Then we might spot something that isn't right.
We'd be looking for upstream modulation fluctuations or high power levels.
The Forum Team take a couple of days to get to a post and any additional evidence you post here will assist your case.
I presume that they want to rule out your equipment as a drop out cause. But here’s the catch: it’ll be just your luck that when they are checking (the couple of minutes allocated to that task), all will be well and we are no further forward. If you are not using a Hub 5X, Do pls take my advice and post your modem stats particularly if you do it during an outage. The community is good at this and the elders know their stuff.
Regarding your setup-please describe it and reconfirm that both WiF and Ethernet cut out fot those 30 or so seconds. The BQM should have reflected the dropout and indeed it is too goodto be true unless you are on Full fibre ( and the I wouldn’t expect modem mode to work).
