Most Motorola routers (including SBG940, WR850GP, and WR850G ver 3) work well with Nintendo DS. However, if you are running into wireless link connectivity/stability issues, you may want to try lowering the transmission rate setting on your Motorola Router to 1-2mbps.

In order to create a wireless link between your Nintendo DS and a Motorola Wireless Router, both of these devices must be setup such that they can communicate/interconnect with each other. Doing so would entail setting them identically -especially the networking parameters (NIC IP Address, Netmask, etc.), data encryption (WEP vs. WPA, etc.) options, and the wireless standards mode (i.e. operating in IEEE 802.11b Vs 802.11g mode, etc.) they are to operate in.

Worry not if this sounds too complicated, because getting it done is just a matter of two simple steps: Step 1. Verify/update wireless networking/security parameters on your WR850G/SBG940/WR850GP router, and Step 2. Create a matching connection profile (using one of the three Connection Save Files -CSF 1, 2 or 3) on your Nintendo DS.

Therefore, this document first focuses on how to discover/configure various wireless networking/security parameters (SSID, Username, Password, WEP key, IP Address, MAC Address, etc.) on your Motorola Wireless Router, and then points you to step by step instruction on how to create and save a connection save profile on your Nintendo DS.

To use the configuration utility embedded within your Motorola WiFi Router, you need to connect to it using the HTTP protocol. Launch a web browser (Internet Explorer, Opera, Firefox, or Netscape, etc.) on your computer, type in http://192.168.10.1 (default IP address for its LAN/NIC Interface) in its URL/Location bar, and then press Enter on your keyboard.

If presented with a user authentication (login) screen, try the following:
Default Motorola Wireless Router Username: admin (lowercase)
Default Motorola Wireless Router Password: motorola (lowercase)

If you cannot login using the above, it may be so because (a) you are not typing your password correctly, (b) your CAPSLOCK key is on, (c) someone has changed password on your wireless router, and/or (d) the firmware (a set of instructions stored on an EEPROM microchip) encoded within your wireless router is corrupted. Consider resetting your router to its factory default settings if you are stuck.

IMPORTANT: Secure your router (by making use of a strong password, WEP Key, MAC Address filtering, etc.) if you wind up resetting (wiped clean) your router to its factory default settings -unless you want to make your entire WLAN susceptible to scammers.

Login to Your Motorola Wireless Router, and Proceed as Follows:

• Retrieve/Change SSID on Your Motorola WiFi Router: From the Wireless tab, go to Basic to review or change SSID.

  Default SSID on a Motorola Wireless Router: motorola NNN (where NNN is the last three characters of the MAC Address printed on the bottom of the router)

• How to Access or Change WEP Keys on a Motorola Wireless Router: To access the WEP information, go to the Wireless, and then over to the Security section of your router's setup utility.

  If you are trying to diagnose/solve WLAN connectivity issues, use a 64-bit (instead of using a 128 bit WEP key or WPA) data encryption key. To avoid complications due to WEP Key mismatch (typing errors, etc.), use a simple 64 bit WEP Key (i.e. a 10-digit Hex WEP Key such as 0123456789 or 7777777777, etc.) during diagnosis or initial setup. Write it down carefully because you are going to need it for configuring a Connection Save File on your Nintendo DS.

• To Verify or Update DHCP Settings on a Motorola Router: Go to the Networking tab, then to DHCP Server area.
  
• To Verify or Update DNS Settings on Motorola Routers: Go to the Internet tab, then click on Basic area.
  
• To Verify or Update Broadcast Settings on Motorola Routers:
  Go to the Wireless tab, then click on Security.

Now that you have verified and documented various settings (such as password, SSID, WEP key, LAN interface IP Address, Mac Address, etc.) on your router, you are ready to proceed to the next step of creating a matching Connection Save File (CSF 1, 2, or 3) on your Nintendo DS using the same. Check out How to Configure Nintendo DS WiFi Connection Save Files to Work with Your Wireless Router for step by step instructions.

For further information on wireless link configuration/diagnosis, please check out additional documentation available at this site and/or at manufacturer's support site. Consider upgrading the firmware on your router -if available. This document applies to the following Motorola WiFi Routers: WR850G, WR850GP, and SBG940.
