I'm having a sort of "issue" when using a Wifi dongle for my Raspberry Pi, after about 3 minutes connected to a router, the dongle starts to heat up quite alot, almost like a mug of coffee, which I find to be very concerning considering that the dongle casing itself is plastic and I don't want to damage the dongle or the Raspberry Pi itself.
This happens when I connect to the Pi via SSH when it's connected to the router wirelessly, now the heating is an issue to me because I was thinking of attaching a USB camera to it, and use it as a web server so I can connect to my Pi and view my camera. Since where I want the camera to be is quite impossible to pass a wired connection, I thought using a Wifi dongle would be a good idea.
Anyone know why my dongle is heating, or if it's dangerous in anyway? I was planning on leaving my Pi on permanently, like a server. What are the dangers of a wifi dongle, that I intend to leave switched on for days at a time?
