No device- or browser-specific settings are used in the guest WLAN.
The WLAN controller sends an HTTP 302 response containing the captive portal page address to the endpoint on the guest WLAN. The endpoint or its browser must follow the link in the HTTP 302 packet. If the redirection works on iPhones and laptops, it means that ClearPass and the Wi-Fi controller are configured correctly.
Verify that Android devices are assigned the correct role on the Wi-Fi network, that they receive a valid IP address, and that they can resolve the FQDN for the landing page via DNS. They must also trust the ClearPass HTTPS certificate-a publicly signed certificate should always be used here.
