I was wondering, I have a garbage wi-fi connection at work, possibly becuase I don't know where it is, lol. Also it tends to fade in and out. Is there some accesory made by nintendo or a third party that will boost my wi-fi connections signal strength?

You can use a larger antenna but it won't really help unless the other end of the wi-fi link also upgrades the antenna. You could put a repeater in the middle.

You could also get Nintendo's USB wi-fi thingy if you have a computer nearby hooked up to the office LAN or some other decent Internet connection (and is running a Windows XP or maybe Vista, though I'm not sure if Vista will work, so you ought to check compatibility beforehand).

The Nintendo Wi-Fi dongle is really good. Its simple to install and easy to use. It means you dont have to change to WEP encryption just to connect your DS.
