Problem: Ring Doorbell 2, Liveview shows black screen or some other error.

Solution: Uncheck Enable 20/40 MHz Coexistence.

Storyline:

I recently bought the Ring Doorbell 2 and spent hours and days trying to get it to work with orbi, following everyones suggestions with MIMU, Beamforming, Daisychain on/of, reserve a static IP address in DHCP.... NOTHING WORKED.

When I say it doesn't work, I mean specifically liveview. This would either come up with a black screen or error messages saying your device cannot connect to ring. For some reason it would work right after you ring the doorbell but a few minutes later it would fail to work. I could actually call from outside the network (ie use cell data) to liveview and sometimes it would work.

I talked to lvl 1 tech support as ring, that wouldn't let you go to lvl2 until you jumped thru the hoops at least 5 times. Finally a lvl2 tech told me that the problem might be because router might be trying to talk to the doorbell on the 5ghz that it would cause interference since ring is only a 2.4ghz. I figured it because they used poor antennas since my Rasberry Pi Zero W is 30 feet away from the router and still is able to get a full signal. In any case, it got me thinking to what the solution is.....This kind will be rude to your neighbors, but atleast in the mean time your ring will work until they get their tech together. Uncheck Enable 20/40 MHz Coexistence. I think what this does, is it doesnt bother with the 40Mhz which I think the ring is having problems negotiating with and strictly uses the 20 Mhz bandwidth. Anyway this worked for me, I hope this helps you because I totally wasted a bunch of time with Ring tech support who had no clue what it could be.
