  2. After the network name table is displayed, click [Hidden network] then click [Connect].

  3. In [Network name], enter “keiomobile2x” and click [Next].

  4. In [Security Key], enter “welcome!”, then click [Next].

  5. Finally, click [No].

  6. Start your Web browser※, enter “https://wifi.keio.jp/” in the address bar, then access the ITC’s web page.
    ※ Using Firefox, the certificate does not download automatically, so access using either Internet Explorer, Edge, or Chrome.
