X-Box 360 Doesnt Access WiFi

I own an X-Box 360 that allows internet access through an Ethernet port. I have shifted houses so I do not have internet access through Ethernet anymore. To ensure that my X-Box is up-to-date as possible, I bought a Wi-Fi (iogear) to be used by plugging it to the Ethernet port, then pressing the wps button. I have done this steps repeatedly but they are not working. What am I missing out? How is the adapter supposed to work?
