I checked the voltage of the adapter that was supplied with my WAG54G. I have a lot of wireless dropouts (I think I tried everything). I don't know why, but I decided to check the voltage of the adapter. And surprisingly that one gave 15V instead of 12V. I cheked on what voltage the gateway started working, and found out it runs on 9V. Let's see what happens with the temperature and the dropouts now. So far, so good.
