I have a network cable from my secondary WAN port on my dream machine running to my first story roof where there’s a wall mount ready for starlink to be plopped in.
I discovered the same thing the hard way myself recently (in Norway); turns out that cell towers only has enough battery for ~24-36 hours (if you're lucky).
However, someone messing with the fibre to my house is a bigger possibility than power outage, so I'll probably end up with this 5G product. :)
I wish there were cheaper 10gb switch from Ubiquiti. The link Agg is good, but still pricey.
