 In a scenario where a customer has multiple Wireless LAN Controllers (WLCs) running N+1 redundancy with Access Points (APs) equally distributed, the critical APs must have priority in case of a WLC failure. If critical APs remain unregistered during a WLC failure, it indicates that the AP failover priority is not enabled globally on the backup WLC. Enabling AP failover priority ensures that critical APs are given precedence over other APs, allowing them to register with the backup WLC first.

 In a wireless design that requires bridging wired IP surveillance cameras through a mesh AP, the cameras should connect to the AP operating in Mesh AP mode (MAP). This mode allows the AP to function as part of a wireless mesh network, providing connectivity to wired devices like IP cameras in areas where it’s difficult to run Ethernet cables.

 In an outdoor mesh network designed to cover sports fields, a 5 GHz, 14-dBi patch antenna is suitable for the RAP for backhaul connectivity. The higher gain and directional nature of a patch antenna help in focusing the signal over longer distances and in specific directions, which is ideal for connecting various points in a large outdoor area5.

The sticky client issue occurs when a wireless client device clings to a suboptimal access point instead of roaming to a better one with a stronger signal. Enabling Optimize Roaming on the Cisco 9800 Series Wireless Controller can alleviate this issue. This feature prompts clients to roam by disassociating them when their signal strength drops below a threshold, encouraging them to seek a better connection.
