On the downside it's not very configurable, like you can't even have separate 2.4 Ghz and 5 Ghz SSIDs.
But your parents probably won't care about that. Just get a three pack, set it up in 10 min, and you probably don't have to worry about it again (until Google abandons that product line like every other).
I don't like mesh and installed the same system that I have at home at my parents. Multiple APs connected to GW/switch with Ethernet.
I got eeros but Amazon hides everything behind a $10/month paywall. I used to run ubiquiti gear but that was too much work.
Is there something in between?
For me it’s telemetry mostly.
