About a week ago both my 3rd gen cameras and saying week WiFi, bought in Jan 24 both have worked no problems since installing and WiFi router has not moved either. Have uninstalled both and then re-installed along with reset. Additionally when using the App it keeps coming up with OOPPS when trying to access the control centre and then authorised client devices and also Amazon account linking.  I have even brought one of the cameras into the room with the router and it is still advise week signal with a RSSI of 75, the camera is less then 5ft from router. We have checked our router, speeds and connectivity are fine for every other device we have in the house. One of our Bedroom Alexa is at the opposite of the house and has to go up the stairs and through 2 brick walls and that works perfect. Any suggestions from the community is greatly appreciated.
