I have a brick home, but the Ring is mounted on a wooden door jamb that is now 5 feet from my closest WAP, which is literally right inside the door.  There is no tinting on my windows.  And even if there were then it, nor Tyvek would affect things given the configuration of my wifi described above.

As I said above, I believe the Ring is the best doorbell cam on the market.  But it's still crap.  And yes, a hobby kit.  A system that holds itself out as a security device should not have this many issues.  I have just gotten off the phone with Ring after 56 minutes.  Their port forwarding requirements are a joke.

Ummm, did I mention that I have worked in IT for the last 29 years?
