      Actually, though, I have heard different; that provided you are on the same exchange, then "who's account it is" is based on the username and password and not the actual line you are using.

      I think the username and password are used for authentification and to prove you are using their router (They didn't originally think anyone would be able to get them out!). This is of course only true on LLU, if on the connect package the username & password are used to route across the BT network and for account authorisaton.
      This is only what I believe I have no proof but it seem to make sense.

      Ok, So if your on the same exchange or not, You can use the same login to handshake, So what does this store, Is this purely for CHAP reasons, Or does it control what sync you get?

      I mean, If someone has Base and you have Max, Can giving them your login fool the system into thinking they are on Max now aswell?
      As really all LLU lines go into the same box, So I would think its something from there that changes the sync ect?

      In the early days when my mum’s router didn't arrive I used my router which is used for my MAX service on her line (different exchange) and it only connected at 2meg as she has base so it’s the line that that determines the speed. All lines may go to the same "box" but they go to separate DSLAM's (I think that’s the word) and each one is configured separately.

      I only got involved in this conversation because I thought it silly to frighten the OP by saying it was illegal to borrow a router whilst waiting for their replacement.

      Actually, though, I have heard different; that provided you are on the same exchange, then "who's account it is" is based on the username and password and not the actual line you are using.
      The ADSL settings (G.dmt or ADSL2+, speed caps, etc) have to be applied before the login process, so those are all set individually for each phone line. This is because you can't actually login until an ADSL connection has been set up - how would the modem send the username and password otherwise?

      Having established an ADSL connection of the appropriate type and speed, the modem then sends the username and password, which handed off to an authentication server which gives a simple yes/no answer to whether the modem should be given an IP address. The authentication server will record the time and date, the username and whether it gave a yes or a no answer.

      Assuming the authentication server can a "yes" answer, the DHCP server will then assign an IP address to the modem, and record the time and date, along with the MAC address of the router and the IP address that it assigned to it.

      Now, imagine an unauthorised access is made to someone's bank account, and the bank's customer has made a complaint. The bank will have recorded the IP address that the unauthorised access was made from and will pass that on to the police, who will then track down which ISP "owns" that IP address, and liaise with that ISP to see who was using that address. Now assuming the IP address was a Sky address, Sky will examine their DHCP records and be able to see the MAC address of the router. Now because the account username is the MAC address of the router followed by @sky.com it should be an easy matter to work out which customer was responsible for the unauthorised access.

      Now what happens if the customer was using a non-Sky router? The MAC address won't correspond to a Sky customer login, so Sky would then have to go to the authentication server records to work out would username was used to authenticate the connection.

      If Sky didn't have a connection username and password that was unique to each customer, they would have much more difficulty identifying who was responsible for the unauthorised access to the bank account if the miscreant was using a non-Sky router.

      So that's why they have unique connection usernames and passwords.
