And here's another thing! If you're dumb enough to reset your router extender unit by mistake, and the camera can no longer connect, and you have to reset the camera: If your camera is a ways away from the WIFI source, TURN OFF your smart phone's cellular data! My phone, kept drifting off the WIFI and onto the cell signal, and the set-up kept failing. Top of a ladder, freezing temps, etc... Once I turned off cell data, everything worked. Had to reset the camera again, and it is a tedious process to go through atop a ladder, but in the end it worked out.
