If you are having trouble with your TrendNet wireless router, check to see if it’s overheating. I was having trouble with mine dropping connections frequently and having to reboot a lot. I happened to feel it and it was super hot. It has some vent holes on the bottom and it was sitting on top of the warm DSL modem. I guess that was blocking the ventilation too much.
I propped it up on the edge so that the ‘bottom’ vents were now on the side and it is much cooler and hasn’t dropped any connections since.
