Re: ''Kevcel's Tetris DS Tourney'' Officially started! i would only recommend buying that if you're running Windows XP. the device is not supported by Nintendo anymore. the software was last updated at the end of last year and it worked on Vista, but as Vista is continually updated there's no guarantee of future compatibility. i got it to work on Windows 2000 with a little effort. it may be difficult or impossible to use it on Mac or Linux. if anyone has a router that isn't officially supported for use with Nintendo products, it might be useful to google your router model and "Nintendo WFC". i was unable to connect through my D-Link router, but after changing the router's transmission rate it works great, and this doesn't seem to have any negative impact on my internet connection. i would exhaust the possibility of using what you have before spending any money. if you've tried everything and nothing works, i think it would be a good idea to buy a router that's gamer-tested and recommended for use with an array of gaming systems (while taking connectivity and reliability into account). this would be a good long-term solution. p.s. anymore, google, and internet are fake words.
