Siemens SpeedStream 2624 Is probably the best wireless router I have owned. It worked great until I decided to flash it to the latest firmware (no particular reason). It has been dead ever since.

SMC SMC7004AWBR 802.11b Router - I had an early version of this. It had to be rebooted every-so-often because it overheated. The bottom of it was metal. You could fry an egg on it. I have a few friends with the same one, only a newer design. They report no problem.
