The TP-Link TD-W9970 Modem Back

The TP-Link TD-W9970 is for use on service over 25 MB/s on networks using Bells' DSL infrastructure. NCF sells these modems for members on 25 MB and faster service.

This is the procedure NCF uses to configure a TP-Link TD-W9970 modem out of the box or after a factory reset. To learn more about configuring your particular modem, consult the manual.

Configure router for Dual Mode ADSL/VDSL operation

Your router can support both ADSL mode and VDSL mode. If necessary, you could switch between ADSL plans and VDSL plans without having to buy a new router or even reconfigure your existing one.

Settings for VDSL

We will start with the mode used for VDSL connections. These include the following NCF DSL Plans:

  • Freedom 15-10/300
  • Freedom 25/300
  • Freedom 50/300

Getting Started

NOTE: If the modem is brand new, "user name: admin and password admin" will gain access. If the modem is not new, it is recommended to reset the modem to the factory defaults by holding down the reset button with a paper clip for 6 to 9 seconds and then do step 1.

1. Once you access the modem browser at and login (user name: admin and password admin), click the link high-lighted in red.

You are done adding the ADSL settings. Now, skip ahead to Wireless Configuration.

Configure as bridge

Do this only if you prefer to use your own external router rather than the one built into your TP-Link unit.

  1. Connect power and turn on the modem with the 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:
  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.

  1. Click on Advanced Setup and WAN Service and click on Add
  2. The defaults are fine; click on Next.
  3. Click on Bridging and ensure the 802.1P and 802.1Q are set to 0 and 35, then click on Next.
  4. Click on Apply/Save
  5. Done!

  2. The SSID is set to NCF plus a random number, such as NCF_123456. It is recommended you not use your first or last name, or street address as this information is broadcast and other people in your area will be able to associate the signal with which home it is coming from.
