La réponse de Nintendo à mon mail : Hello and thank you for contacting Nintendo,
If you´re wondering if your wireless router is compatible with the Nintendo
Wi-Fi Connection (WFC) service, please don´t worry--it most likely is. Most
routers that support the 802.11b wireless communication standard (or 802.11g
routers that are backwards compatible), with either no security or WEP security,
are compatible with the Nintendo DS and the Nintendo Wi-Fi Connection service.
If you need more details on using your existing router with our service, please
visit the following section on our website:
http://www.nintendowifi.com/consumerservice/routerSetup.do
On this page you can search for your router by manufacturer, then by model
number to get in-depth manual setup instructions to get connected to the WFC.
If you don´t happen to see your particular router listed here, head to the Tech
Support area and click on Getting Started. There is a step-by-step procedure to
get you hooked up.
If you have additional questions or concerns, please let us know!!
Sincerely,
Nintendo of America Inc.
