"a router that couldn't reconnect to the internet after cycling the power."
I had a TP-Link do that. It was a firmware bug and eventually they sorted it. But six months later. For consumers they won't wait that long.
I purchased this router several months ago and have had nothing but problems with it. It feels like a work in progress.
The first unit I purchased bricked after upgrading the firmware and after contacting Synology they recommended returning it for repair.
The replacement unit seemed to work OK until I powered it off. Upon powering up it would not connect to the internet - it saw the modem briefly but then dropped the connection. I did a complete Reset via the router control panel software and went through the setup process again. Everything worked fine until I upgraded to the firmware from Synology; again I had to do a complete reset to get it to connect to the cable modem. Similarly the same thing happened when I cycled the power.
To say I'm disappointed is an understatement. I have never had a router that couldn't reconnect to the internet after cycling the power.
