All of My 12 cameras act this way plus Outdoor cam and Pan Cam.
Using Samsung Galaxy S9+
If Wi-fi is OFF, camera connection is flawless.
if Wi-fi is ON, no cameras connect.
Like others say “They used to work in the past” with wi-fi ON.
Suggestions?
Thanks, Bob
Hi, But there’s not enough info to help you. The cameras only work on WiFi. So, have no idea what you mean by WiFi off.
Thanks, Sam! I have no other information. except to define what I mean about Wi-fi off. Wi-fi off means Wi-fi is not connected to the network. Things that use Wi-fi, other than Wyze can not use Wi-fi because Wi-fi is off. I don’t know what further I could provide to further the explanation of the problem. When Wi-fi is ON, my camera’s are not connecting. When Wi-fi is OFF, they connect.
Appreciate your feedback.
Do you mean that WiFi is turned off ON YOUR PHONE?
If that is the case, have you made any changes to your WiFi network?
Yes, K6CCC. OFF on the phone. No changes to Wi-fi, it is as it was.
To be clear, you are referring to a home WiFi SSID to which your wyze devices are connected and not the hotspot offering WiFi from your Galaxy S9+, correct? And you’re saying that you can view cameras and manipulate other wyze devices attached to your home WiFi when using the carrier’s data connection but not when the phone is connected to the same home WiFi?
Assuming my synopsis is correct, are there any other devices in your household to use as a control test here? Like do you have a tablet or do others’ phones exhibit similar limitation? Also, is the phone limited from connecting to other things when using the home WiFi, or is wyze the only thing troubled?
He may be referring to OFFline screen?
Which returns us to this point…

Yes, A home Wi-fi SSID Not Hotspot. Hotspot is and has always been disabled
And you’re saying that you can view cameras and manipulate other wyze devices attached to your home WiFi when using the carrier’s data connection but not when the phone is connected to the same home WiFi?
Correct-mostly. Speaking about Cameras only. Can use mobile but not Wi-fi. I have not used other Wyze products in this due to other factors which are fixable, just have not gotten around to it.

Wyze cameras are the only troubled items. All other non Wyze devices work as advertised. Wi-fi ON = connection. Wi-fi OFF = no connection

Might be because your 2.4 Ghz and 5 Ghz WiFi segments have the same SSID (name)? Most Wyze gear supports only 2.4 Ghz.
Edit: maybe trade phones with this guy? 
Oh, also, why does your other gear stop working when WiFi is off on your phone?
I was thinking something along these lines with perhaps a meshed system that needs tweaked to allow proper functionality for 2.4GHz band exclusive devices like Wyze. I use a separate AP for my 2.4GHz radio only and my firewall/router 5GHz band is actually a different SSID but still on the same broadcast network as Wyze. I’ve used devices that manage things by either proprietary/provisional protocols that alienate either my Wyze or Roku stuff. Solution ends up being disabling the caterpillar drive and engaging normal propulsion screws… 
EDIT-1: @Bobbert, I also want to add that I have seen firmware from Wyze addressing better meshed network performance over the years. Probably a good idea to verify that all of your cams & wifi router itself are current.
This control test is key… If an alternate device SUCCEEDS on the same WiFi, I’d lean towards @Bobbert performing a network reset on his S9+.
If other devices exhibit the same trouble, I’d wager there’s some firewall rule or other restriction in place needing easement, possibly even this end-user’s phone inadvertently blocked. Orbis can block individual devices via their interface at layer 2 and I’m sure other spiffy home systems have similar granular facilities.
EDIT-2: Also, @Bobbert, this might sound like a styoobid question, but have you bounced your wifi router recently?
Wouldn’t it be great if we could just swap problems like commodities?! Imagine the supply & demand dynamic there…

Yes, Swapping phones with the gentleman might be worth it!
> Might be because your 2.4 Ghz and 5 Ghz WiFi segments have the same SSID (name)? Most Wyze gear supports only 2.4 Ghz.
How is it possible to have the same SSID for 2 Wi-fi connections? Mine however are:
Bohica2.4G and
Bohica5G
Bohica2.4G is my sole connection for Wyze devices
> Oh, also, why does your other gear stop working when WiFi is off on your phone?
Perhaps because the Wi-Fi is turned OFF. 
But you defined “WiFi off” to mean you’ve turned off WiFi on your phone.
That wouldn’t keep other home WiFi devices from operating properly.
If you are now instead saying WiFi off means turning off the WiFi radios on your router, then of course no home WiFi devices could work at all.
Anyway, many mesh systems use the same SSID for both frequencies but apparently that doesn’t apply to your setup.
No mesh Router
Not a cold boot but a couple of warm boots when changing some IP addresses
Higher-end routers do this. It’s a way to make connectivity seamless for all devices such that folks don’t have to worry about the radio bands.
Are you certain that your 2.4 & 5 GHz bands are on the same broadcast network? If each band uses a different subnet somehow, that could explain your inability to manage wyze with Wi-Fi enabled on your phone.
Have you tried using the 2.4GHz network directly from your phone instead of the 5GHz?

Yes

Another reason for this is that 2.4 GHz signal travels further while 5GHz might attenuate at the same distance. Smart routers intelligently determine what is offered to your device based on signal strength to mitigate this. Closer in, they keep you on the 5 GHz band for better performance, but might then move you over to 2.4 GHz if the signal wanes.
Here’s how I might proceed:
Have you tried forgetting your home Wi-Fi network from your phone? I would try that, wait a few minutes and then rejoin.
Maybe check to see whether or not you inadvertently enabled some security rule blocking access from your phone while attached to the same LAN.
Perform a network reset from your phone. You will have to rejoin any Wi-Fi networks of which it was aware prior to the reset is the main fallout from this.
