As long as you have set the transmission rate on this Microsoft wifi router (MN-500) to 1-2 mbps, you should have little (if any at all) difficulty in using it with your Nintendo DS WFC. If you have a different Microsoft Wifi Router (such as one of their newer models MN-610, MN-620, MN-700, or MN-820), you may be able to get away with a higher transfer rate setting. To be on a safer side, we will focus on how to configure/use the original (MN-500) Microsoft wireless router -which, we believe, would also apply for most of their aforementioned newer versions.

To establish a wireless link between your Nintendo DS and Microsoft wireless router MN-500, you need to set both of them so as to use known/valid networking (IP Address, Netmask, etc.) parameters, identical data encryption (WEP vs. WPA, etc.) methodologies, and mutually supported wireless protocol (IEEE 802.11b Vs 802.11g, etc.) standards.
