The Easybox 805 is a pure DSL router and can NOT be used for cable internet via the TV cable connection.
Where did you get the device from? If you received it from Vodafone, then you definitely didn't order cable internet, but rather a DSL connection (via the telephone line).
There is no installation code or password for cable internet because the devices log in to the CMTS and are activated via the CM-MAC.
