Adtran gateways come from your provider

Adtran makes equipment for internet providers, including the SDG series of home gateways that many fiber and DSL providers hand out. You rarely buy an Adtran router yourself, so the login details usually come from the provider.

How to log in

  1. Connect to the gateway by Wi-Fi or cable.
  2. Open 192.168.1.1. Adtran’s SDG user guide gives this as the default address; the sign-in page appears.
  3. Sign in with the username admin and the password from the gateway label or the one set during installation. One UK provider’s guide, for example, describes the password as the one set up at installation.

The older Adtran models in our database, 1004W and 1004WB, use admin / admin. Treat that pair as a starting point only: provider units are usually set up with their own password.

Plume-managed gateways

Some Adtran SDG units run PlumeOS firmware. Adtran’s guide says to follow Plume’s documentation for those units instead of the SDG guide, so check with your provider which app or page manages your Wi-Fi.

When the login fails

  • The page does not open. Check your default gateway; the provider may have set another address.
  • The password is rejected. Ask your provider for the admin password before resetting.
  • A factory reset (hold the Reset button on the back for several seconds) restores the defaults, but it can also erase the provider’s connection settings.
