I’m a certified network engineer so I wasn’t too fussed with their support. I have a Dream Machine, a 24 port PoE switch, two APs (one U6 Lite, and one U7 Lite that I added later), and three cameras. We mostly just use the cameras to check on the cats when we’re out of town, but it’s nice to have the extra security just in case.
Is the setup a little excessive: absolutely. Is it awesome to know within seconds if there’s an issue with my network or if it’s just another ISP outage: also yes.
In the five years that I’ve had this setup, I’ve had exactly one issue with the network and it was just that one of the APs died after four years of continuous use.
That sounds like an issue with Mullvad to me. I haven’t used it personally, but a quick search pulled up some issues with Mullvad leaking location over ipv6 and even disabling it by default.
