This just started happening to me this past week. My RSSI was around -60, which seemed like a large value, so I got a Wi-Fi repeater and installed it near the front door. I then reconnected my doorbell to my network to ensure it was connecting to the repeater. RSSI now shows at -36.0. However, I was still unable to connect for a Live View, and recordings were still showing up black.
I saw another post that suggested removing the device from the app and going through the setup all over again. So, I did exactly that - deleted the device from my app, reinstalled the app, connected the Ring doorbell as if it were a brand new device .
This seemed to slightly improve the issue, but it’s still a long way from fixed. About 2/3 of my motion-detected videos are completely black. My Amazon Echo Show has so far been completly unable to make a connection when I ask it to show me the front door. I can get a connection from my phone once every three to four tries; when my phone isn’t able to show me a live view, I find later that there is a “Live View” event in my history that has a black video. The app on my Windows 10 PC has about the same failure rate as my phone (it will show “Connecting” for a few seconds, and then just drop back to the device view instead of showing video). Videos that are all black, are all black no matter where I attempt to view them (phone or PC, app or website). [None of these problems existed last week.]
The Ring app has a function to check the Wi-Fi speeds, so I did that standing right next to the doorbell, and I got just over 20Mbps download and 5Mbps upload, which is well over the 1Mbps recommended. I fixed the signal issue with a Wi-Fi repeater. The device health page is showing that it is hardwired at 100% battery, and the firmware (checked 55 minutes ago at the time of this post) is up to date. Everything looks like it should be working.
I see that this issue has been posted a few times, but most are marked as “Solved”; but the solution doesn’t seem to be working for me.
