To set up the wireless display, connect the laptop or computer to a nearby Wi-Fi router. If you use a laptop that is new and hasn't yet been set up with a Windows Live Connection, then the best way to go about setting this up is to go into the control panel and click on 'network settings' then click on 'internet options'. Once you have done this you will see a series of three boxes - one for the SSID, one for a password, and one for your network's name. Give the name a nice name like'sbmi1' without any spaces in it, and click on 'OK'.
Now you have to connect the WiDi adapter to your Windows Live Connection. To do this you should click on the start button on your computer then right click on 'Network settings' and select 'wireless networking'. Finally, you should click on the 'additional adapters' tab on the main window then click on the Wi-Fi adapter you have just added.
