I have a 4th Gen AirPort Extreme lying around I think of using to extend my WiFi to cover my back yard and pool. I want mount it on the ceiling of my covered patio. Anyone know the temperature range of these things? It gets hot here in Cali. I am worried about the heat even though it will be under a patio.. Also can I use a plastic bag to protect it from the misters on the patio cover or will that mess with the ventilation??
