Configuring most of the newer US Robotics Wireless Access Points, US Robotics Routers and USR Gateways to support the good old 802.11b (wifi) interface built-in Nintendo DS gaming consoles is not that difficult -thanks to the fact that all such USR products (including their MAXg/802.11g based devices) provide backward compatibility to IEEE 802.11b standards.

Considering that most of these newer USR wireless products have many advanced features (such as Stateful Packet Inspection firewall, Wi-Fi Protected Access WPA and WPA2, WPA2/802.11i, WPA PSK, TKIP and AES Encryption, WDS Restrictions, and support for MAC address authentication), you may have to disable (or slacken) some of these advanced features to allow traffic from your Nintendo gaming console to get through.

In order to setup wireless connectivity between your Nintendo DS and a US Robotics device, you need to configure one of the three Connection Save Files (on your Nintendo) such that it knows the specifics (SSID identity, Network Address, Netmask, Password, WEP Key –if any, etc.) of the USR product it is supposed to uplinked to. Therefore, your need to first discover (and if needed reconfigure) settings used on your USR device, and then use that information to configure one of the "connection save files" on your Nintendo DS.
