[quote name='ps2rich']Any tips or tricks for use with the 360? [/QUOTE]
Plug one end into your 360 and the other end into your router. They are not a piece of networking equipment per se. Any configuration will be at your router and the network protocols it uses to talk with your console.
The best way to explain them, is that they are a single ethernet wire, cut into two pieces, that still works. There is no set-up, no configuration, other than just plugging them in and turning them on.
