FAQs: Guest Portal

Why is the captive portal (or splash page) not coming up when I try to access the wireless network?

This could be caused by a few issues. If the splash page is not coming up when you try to access the wireless network, try the following suggestions:

• Ensure that the Mist Portal FQDN for your regional cloud instance (such as http://portal.mist.com , http://portal.eu.mist.com, and so on) is permitted through the firewall. For FQDN and port details for all cloud instances, see Juniper Mist Firewall Ports and IP Addresses for Firewall Configuration.
• Verify that the client has a valid and working DNS entry, which is needed to resolve the client captive portal URL.
• Check the WLAN setting to see if the guest portal is configured correctly. You can use the custom guest portal option on the Mist WLAN page to design a splash page in the Mist Cloud. For more information, see Add a Custom Guest Portal to a WLAN.
• Ensure that the client is receiving a valid IP address. To verify this, look for the client in the active Wi-Fi client list, and select it to see the details and client events.
• Use Marvis Conversational Assistant (if enabled) and troubleshoot <client mac address>.
• Ensure that you are connected to the correct SSID.
• Sometimes, Windows systems or Apple CNA browsers do not load the splash page automatically. In such cases, open a browser and try entering an HTTP URL such as http://neverssl.com manually. This applies if the client has an IP address.

If the above suggestions do not help, contact Mist support.

Note that the splash page might not come up if the guest is already authenticated.
