I've had problems where my wifi connection on my Wrt54g router would randomly drop signal. I could be 1 foot from the thing and it could not find the SSID. I then noticed that the thing was getting quite hot! I flipped the router up so that the face is pointing down and the unit is sitting vertical as to allow air to pass through the vents. I stuck my 7dbi antennas upwards (angled) of course. So far the connection has not dropped once, and it has been quite a few days now. The unit is also much cooler. Anyone think this really could be it? Or maybe I've just been having extremely good luck the past few days!
