Losing internet periodically

[Zorquan81]

Hello all. I've installed an opnsense firewall at my parents house. I'm really far away and I can't understand what I'm seeing here. The data is from a ubiquity key, as there are no open ports.

It's running on a jasper lake device, sitting right downstream from the provider modem.

I spent a few weeks with opnsense before doing this installation and believe everything should be working perfectly. There's no VPN, no vm, IDS/IPS. Stock, barring some power and CPU settings
