Why does my internet connection stall out when playing online scrabble or downloading streaming video?

I have tried replacing my ethernet cables thinking maybe that had something to do with it. I can do both of these things fine on a laptop computer that gets its internet signal from the wireless router. I've also checked all my internet settings and everything seems to be the same.|||An internet connection can become slow or stop working due to a number of reasons depending on the type of the connection. Many of the problems can be solved by making software changes or small hardware corrections. Detailed instructions at http://tinyurl.com/yl62gz
