You are too kind. I had been a Linksys customer since they introduced their very first Wifi router. Velop was the end (AC2200 series for those who are curious). Every single firmware upgrade left me on the phone with support for HOURS. Even when it wasn't in meltdown I had all sorts of issues with nodes dropping off, not being able to connect to a node sitting next to me, compatibility issues, etc. I came back from vacation one day and my entire network was down. Surprise, surprise - they had pushed an update while I was gone. When I called support they said my nodes were too far apart. Yup, that's what happened - nothing to do with your crappy firmware update. Rather my house was replaced by a TARDIS while I was sailing in Belize.
After that experience, I disabled auto-updates and just let it run, but I still had tons of problems and when I called support their first answer was "well, you need to update your firmware." I don't know if it was the hardware or their development process or both but I will never, ever, ever buy a Linksys product again. Or WeMo for that matter.
I ripped all that stuff out last September and went with Unifi - a life-changing event. My RTL from my house to our MSP data center went from 150ms to 37ms. Packet loss dropped to zero. No outages, every firmware update has been a breeze (though I do not do automatic updates), Our game room doesn't go offline periodically, my ecobee stays connected, and the whole thing is a ton more secure.
Lessons learned from my adventure:
(1) stay away from consumer-grade stuff
(2) hard wire where possible
(3) no non-managed devices
(4) wireless backhaul is a compromise I'm not willing to make
