Type this, not a search

// address bar

Address bar

http://Ntt.setup

  1. Use the browser address bar. A search box will look up Ntt.setup on the public internet and miss the router.
  2. Type http://Ntt.setup with no www and no https. You must be joined to this router's Wi-Fi.

  • Type in the address bar, not a search engine

    Enter 'http://ntt.setup' directly in your browser's address bar—searching for 'Ntt.setup' will not take you to the router admin page.

  • Do not add 'www' or 'https'

    Ntt.setup is a local hostname; adding 'www' (e.g., 'www.ntt.setup') or 'https://' will cause the page to fail to load.

What is Ntt.setup?

// briefing

Ntt.setup is a local web address that gives you access to the admin panel of your Ntt. router. This address only works when you are connected to the router's network — it does not resolve on the public internet.

Compared to a numeric IP address, Ntt.setup is easier to remember and is provided by the manufacturer as a convenient alternative for accessing the settings page.

This hostname is specific to Ntt. devices. Other manufacturers use different addresses — check the sticker on your router for the correct URL.

The default login credentials for devices accessible via Ntt.setup are typically username user and password admin.
