We had a month-long internet outage and after our 5G internet service was reestablished by the provider with a new Wi-Fi password and modem, I can't get our TAPO-C520WS cameras to work. 

Here's what I've tried:

• Selecting them in the app and updating the wi-fi connection info

• Resetting both cameras multiple times, then trying again in the app

• Deleting the cameras from the app and adding them again

• Looking for the cameras in my phone's wi-fi list

The problem appears when the app says the camera should be flashing red and green.

----------------

Ours don't - they just flash red.

----------------

When I click on the 'not flashing red and green' link in the app, it says to reset the camera and then it should be flashing red - which it is.

----------------

But then the app just takes me back to the earlier page which wants the camera to be red and green.

And there's no info on how to proceed if the camera is just flashing red.

And the cameras are still not showing up in the wi-fi list.

----------------

FYI I can't reconnect my smart bulb either, but Google tells me it won't work with 5G.

----------------

FYI I'm in Australia with Optus, using an HFC internet connection.

Any help on how to proceed is appreciated.
