At my house I have a WAP54G, POE module and a Hyperlink 100mw amplifier mounted inside of a weather proof plastic enclosure I bought at Lowes'. The cables going in (ethernet) and antenna lead are sealed with silicone. I had to remove the enclosure from the WAP so that it would all fit comfortably inside of the box. It sits outside just as it has for the past several months and it's connected to a Hyperlink 24Db dish antenna. I pick up my internet connection from a friend about 1/3 of a mile away through trees etc. It's working fine but I was concerned about how high the temperature would get inside of the box on a hot day so I decided to find out... What I did was take a wireless thermometer unit that I normally have mounted under my back porch to sense the outside temperature and send it to the inside unit(just one of those you can buy at Wal Mart etc and I put it inside of the enclosure and then screwed the lid down tight again. I did it last night and right now this morning it's about 70 degrees outside and my thermometer is measuring about 85 degrees. It's supposed to get to 90 degrees outside today so lets see how high the temperature goes. The unit is in a somewhat shaded area as afternoon comes around so let's see if it stays at 10-15 degrees above outside ambient air temperature. If so, I don't think the WAP will ever have a problem.
