Actiontec wireless router model # GT701-WG seems to be compatible with Nintendo DS –especially if you have the latest firmware running on your GT701-WG. Actiontec GT704-WG, on the other hand, is known to have issues communicating with Nintendo DS WiFi interface.

You will greatly improve your chances of making your Nintendo DS successfully connect to an Actiontec wireless router by ascertaining that you have the latest firmware/software running on your router. This is especially important if you did not purchase your router directly from a vendor recently, but received it packaged (i.e. bundled with a DSL service from a DSL provider such as Qwest, etc.) with a broadband service. Check with your broadband service provider if they have a custom-firmware upgrade available for your router.
