What does the Xbox 360 Wireless Adapter Do?
It allows your xbox to connect to your router wireless. This means you can connect to xbox live without using an ethernet cable. However the wireless adapter won’t work if your router can’t pick up wireless connections (it should be able to though). The Wireless adapter is good and useful, as it means you don’t have to get a ridiculously long cable to go through your house to get to your router (if you are far from your router). But the connection isn’t always as good, I have one and now and then my connection isn’t perfect.
