Nest cameras slow / disconnecting DNS fix

Just FYI incase this helps someone else, but my cameras were very unresponsive and losing signal often. I have very strong overkill wifi setup, so I knew that wasn't the issue. I had my network set to Quad 9 DNS.

So, after being frustrated by their dropouts for awhile now -- I decided to investigate further, and only thing I could think of was DNS. So I hardcoded the cams to Google public DNS & suddenly they're operating much better!

I have 2.5gb internet /w low ping, etc. so connection should never have been an issue. But apparently they weren't resolving properly via Quad 9.
