You'll configure your router to operate in dual mode, so that you can start with an ADSL plan if you wish, but be able to upgrade later to a VDSL plan without having to reconfigure your modem (plug and play). Your router will work in VDSL mode as well, should you be starting out with a VDSL plan.

  4. If the modem is fresh from the factory, use the default user name and password to gain access
    1. user: admin
    2. password: admin

If the modem was previously configured for someone, the password would be the previous user's DSL-Password. If it is unknown then do a reset to factory default, using a paper-clip in the reset hole on the back. Hold for 6 to 9 seconds to reset. The user name and password will now be as above.
