Add WAN Service for ADSL

This section is for configuring your router to operate in dual mode, so that it will handle either VDSL or ADSL2+ connections without any reconfiguration required to go from one mode to the other. ADSL plans include the following NCF DSL Plans:

  • Freedom 6/300
  • Freedom 7/300
  • Freedom 15-1/300

Configure as bridge

  2. Connect an Ethernet LAN cable to one of the yellow rear ports
  3. In the browser's address bar, enter the IP address for the modem interface page: 192.168.1.1
  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.

  4. Click on Apply/Save
  5. Done!
