Yeah no, I don’t understand how that could possibly be worth the trouble unless you value the tinkering for its own sake. I care about my router wifi reliability a great deal, connections that like flake out briefly for one second every day are rage-inducing. Speed when it does work, not as much.
The main thing for me has been to read Amazon/Newegg negative reviews very carefully on routers to see if even a single person is believably complaining about flaky connection. If so it’s a no buy. (I don’t care about the inevitable one stars complaining it didn’t work at all.)
Currently I’m on a Google WiFi (a single unit, not big enough place to need the mesh feature). I was a little worried about the only two bands and the auto band switching since I’m in a large apartment building, but it turns out to work perfectly. I chose it mainly for peace of mind around security thanks to the autoupdates.
