The PC does not have to be left on and it is not stored in the modem. The modem with still sync and 'work' without an autentication - the authentication just allows you to pass data and use it...simples.

Ah, so the user name and password is stored in the router and it is the router that passes that info to the modem, like when we used to have ADSL modems on the USB ports and had to get windows to authenticate.
I know that a ADSL router/modem will sync before any authentication, but will not pass data.
I get it now. so in theory you can just connect a computer to VDSL modem and get the Os to pass the authentication, sort of like we did in USB modem days? Not advisable due to lack of firewall and also not being able to use multiple devices but it can be done.
