How do I allow guest Wi-Fi access when Captive Portal services are unavailable during Wi-Fi Cloud upgrades and maintenance?
During Wi-Fi Cloud maintenance upgrades when Captive Portal splash pages are unavailable for Guest Wi-Fi access, you can configure your Captive Portal settings on your guest SSID to allow temporary access until the upgrade is complete.
You can use these methods:
Disable the captive portal and use a WPA2 PSK password for the Guest Wi-Fi SSID instead of a portal
With this method, you can disable the captive portal and use WPA2 security with a passphrase for guest Wi-Fi SSID access.
The AP Hosted Splash Page for Click-through portal option allows your guests to use simple click-through authentication utilizing a portal based on the AP itself.
Increase the Login Timeout on the Captive Portal
Client devices that authenticate to the Captive Portal prior to the maintenance window will continue to have Internet connectivity via Guest Wi-Fi as long as the login timer does not expire. Increase the Login Timeout of the portal to ensure that client devices will not timeout and attempt to reauthenticate during the Wi-Fi Cloud maintenance window.
