What is the maximum number of APs supported on the 4402 and 4404 wireless LAN controllers (WLCs)?
The limitation on the number of supported access points is based on the hardware that you have. The 4402 WLC with two gigabit Ethernet ports comes in configurations that support 12, 25, and 50 Light Weight Access Points (LAPs). The 4404 WLC with four gigabit Ethernet ports supports 100 LAPs.
Note: Mesh access points are also available in both indoor and outdoor deployments. For more information on number of access points (including mesh APs) supported on each controller model, refer to Table 8-3 Mesh Access Points Supported by Controller Model in the Controlling Mesh Access Point section of the Wireless Lan Controller Configuration Guide 6.0.
You cannot increase the number of supported access points with only the configuration of the access point.
