Modem Configuration (DSL) TP-Link 8950ND

The TP-Link 8950ND modem

This is the procedure NCF uses to configure a TP-Link 8950ND modem out of the box or after a factory reset. To learn more about configuring your particular modem, consult the manual.

Note that the interface for the 8950 is quite different from the 8816, 8901G and the 8951ND and the set-up procedure is also quite different.

Configuring as a Router

  1. Connect power and turn on the modem with the black button on the back.
  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: http://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 20 seconds to reset. The user name and password will now be as above.
