FUCH TAPO. seriously, wha da faaa is this sheit.

What the... 

I set up everything beforehand and then go to the location where I will use camera. Wall mount and try to change WiFi and it's not possible. Can't believe this. I'm pretty sure that seller don't take back camera because it's already used. This WiFi change feature is basic setup thing and now i have readed from here that TP-link has got feedback long time and it's not fixed????

  @celeritas_216 came back to check and see if this has been updated. I overcame this hurdle of using the camera in 2 homes by making the wifi password the exact same. Problem solved so I thought...now i went to add a new TP automation to Alexa and a new compatible light which required 2.4 so i connected it to 2.4 and updated the information only to have that command somehow take ALL of the TP cameras offline because they cannot connect to the network that they're supposed to remember. I did not change ALL of the cameras and this feature to change the network all at once is not supposed to exist. Yet somehow here I am with 5 cameras that I'm supposed to relink one at a time for an issue I do not know how I arrived at. These cameras need to be removed from the Amazon app as they are just more of the same advanced technology completely hindered by an outdated concern. 

  @njgirl  If your cameras all disconnect from home Wi-Fi suddenly, try to reboot your router, reboot the cameras, and check if they will reconnect to the home Wi-Fi.
