	Aside from identifying your box, the service would also use your SSID to determine the manufacturer of the box you connected with. This would be used to tailor the user's experience depending on what box they had, such as showing the proper Internet Terminal name and remote layout during registration and adding a set of favorites determined by the manufacturer after registering for an account.

			The SSID's checksum is validated by the box and if the checksum is invalid, it will refuse to boot.
