Yes we are having the same problem. My info has it that it's the Thompson modem. It overheats very quickly then cuts out. The advice I got from someone in the know is to stand it on its side so it's as well ventilated as possible and if you can, cool it with a fan or aircon. I hear it has a 1 month warranty only. Makes you think doesn't it?..... I will be re installing my Linksys router as soon as possible.
