WIRELESS NETWORKS
All Windows PCs include a feature that can save your current wireless network’s name, password, and other information to a USB stick.
According to Gizmodo, you can use the USB to quickly connect to your wi-fi network on other computers without typing the password over and over again.
And, it even quickly connects an Xbox 360 to your wi-fi network – select the Windows Connect Now option while setting up a wireless network on your Xbox.
Unfortunately, this only applies to Windows.
