Which unified AP mode continues to serve wireless clients after losing connectivity to its Cisco WLC?

FlexConnect mode allows an access point (AP) to autonomously handle client authentication and data forwarding even when it loses connectivity to the Wireless LAN Controller (WLC). This is crucial for branch office deployments where WLC connectivity might be intermittent or unavailable. The AP caches client information and continues to operate as a standalone device, ensuring uninterrupted wireless service. Local mode APs require continuous WLC connectivity for all operations; if the WLC connection is lost, clients cannot connect or pass traffic. Mesh mode APs are used for extending wireless coverage in areas without Ethernet cabling and still rely on a backhaul connection to a WLC, directly or indirectly. Sniffer mode APs are dedicated to capturing wireless traffic for analysis and do not serve clients.
