From Nwizard:

"For those still stuck on landlines, tied down by pesky wires, Nintendo has the solution. Nintendo will soon be producing a router that will allow access the Nintendo Wi-Fi Network on both the DS and the Revolution. The router plugs into a USB 2.0 port and transfers your computers internet connection wirelessly into your next-gen Nintendo devices. Nintendo feels this is a easier and better solution than providing an accessory to allow a hardline connection, and I tend to agree.

Details, pricing, and release date have not been announced."
