Yesterday, I have configured a Belkin Wireless DSL/Cable Router for using with my Pegasos. Of course not via a Wireless PCI card (that is plugged in my PC, but there is a DRIVER for it). I simply plugged an ethernet patch cable into the back of the router (has 4 such ports), this product also acts as a switch. All I did was configuring Miami (not even MiamiDX) and the router is being configured via a web page interface.

I am preparing a tutorial about how to share your cable/DSL connection to a Pegasos, so if you are interested, I may be quicker :))
