We are making available the following configuration script for Windows: SIN Net Setup – Windows (version 1.2)

  2. Run sin-setup.bat with a double click.
  3. Press Enter and then choose 1 - Configure Wi-Fi connection by pressing number one on your keyboard, followed by Enter.

  4. After a short wait, you should see the login fields. Please fill in your SINIS login e-mail (all lowercase!) and password and confirm by OK.
  5. If you followed these instructions and your password was correct, you should get connected. If not, there might be a hidden window in the background, which will ask you to verify the server identity. Please check that the certificate is issued by AAA Certificate Services, the host name is radius.sin.cvut.cz and/or the fingerprint of the certificate is the same as at Certificates - verifying our network identity and click Accept / Connect.

Sometimes the login needs to be repeated two or three times. You may want to verify that your email and password is correct.
