I've been troubleshooting for weeks trying to eliminate all variables (ethernet cables, switch, etc) and still happening. Anybody else ever seen anything like this? I have a lot of smart home IoT devices (60-70 connected at any given time) and wondering if I've hit some critical mass of devices that it can't handle very well?

Anyway, if I can't solve it soon I'm going to buy new gear. Any thoughts on Nest vs Nest Pro? I know Nest has been discontinued on Google's website, but you can get it pretty cheap on Amazon still. Anybody have another brand they just absolutely love. I'm not totally tied to Google, but just love the ease of setup and family control stuff.
