RTA100+ - How do I Change the ADSL Modulation?

Share |

Please do the following steps to set the ADSL Modulation on the modem to G.DMT:

  1. Click on the Start Menu, and choose "Run".
  2. Type in "cmd" without the quotes. Press Enter on the keyboard, or press the "OK" button.
  3. Type in "telnet 192.168.1.1" without the quotes. Press Enter on the keyboard.
  4. You should be asked for a "login". Type in "admin" without the quotes. Press Enter on the keyboard.
  5. You should be asked for a "password". Type in "admin" without the quotes. When you are typing the password, the actual letters that you are typing may not appear on the screen. If this happens, this is normal, as this is how the Telnet application works.
    Simply carefully type the password, and then press Enter on the Keyboard.
  6. Type in "dsl config gdmt" without the quotes. Press Enter on the keyboard.
    A message saying "Set Done" should appear.
  7. Type in "commit" without the quotes. Press Enter on the keyboard.
    A message saying "Set Done" should appear.
  8. Type in "reboot" without the quotes. Press Enter on the keyboard.
    The modem will now reboot. Please wait for approximately 2 minutes, then close this window that is currently open.

After doing this, the ADSL Modulation on the modem will be in G.DMT mode.
