It is not uncommon for devices like these to not be compatible with wifi passwords with non-standard characters in them (even spaces). Try it again with your wifi set to a (temporary) password that has only numbers and letters to rule this out.So, I ended up purchasing the LaView rebrand of this doorbell (http://www.amazon.com/dp/B07LFP9C9C) and I'm quite disappointed. I couldn't even set it up. The physical setup was incredibly easy, but when I went through the setup with the app, it just wouldn't complete. When I used the android app, it said that the device wifi password was incorrect (even though I was able to connect to the device's wifi network through my phone's settings just fine), and when I tried the iOS app out of curiosity, it sounded like it was going to complete the setup, but it kept saying that the wifi (assuming my home network) password was incorrect (it was not, I checked it over and over again, and tried to reconnect my phone with the same password with no issues). I've spent so much time just trying to get this setup, that I think I'm just going to return it as defective (perhaps it is and the wifi module/code is having issues). I might try moving the router closer to the doorbell to see if maybe it's just reporting the wrong error (I tried using the app signal tester, but it was completely in Chinese.........this app is garbage).
I use the RCA or HiVision app and they both work very reliably.
