Cisco Cisco 4404 Wireless LAN Controller

The controller GUI requires the following operating system and web browser:

Windows XP SP1 or higher or Windows 2000 SP4 or higher

Internet Explorer 6.0 SP1 or higher

Internet Explorer 6.0 SP1 or higher is the only browser supported for accessing the 
controller GUI and for using web authentication.

Software is factory installed on your controller and automatically downloaded to the access points after 
a release upgrade and whenever an access point joins a controller. As new releases become available for 
the controllers and their access points, consider upgrading.

The Cisco WiSM requires software release SWISMK9-32 or later. The Supervisor 720 12.2(18)SXF2 
supports the Cisco WiSM software release 3.2.78.4 or later, and the Supervisor 720 12.2(18)SXF5 
(Cisco IOS Software Modularity) supports the Cisco WiSM software release 4.0.155.5 (with Cisco IOS 
Software Modularity).

To use the Cisco WiSM in the Cisco 7609 and 7613 Series Routers, the routers must be running Cisco 
IOS Release 12.2(18)SXF5 or later.

The Cisco Wireless LAN Controller Network Module is supported on Cisco 28/37/38xx Series 
Integrated Services Routers running Cisco IOS Release 12.4(11)T2, 12.4(11)T3, and 12.5.

When you use the controller in the Catalyst 3750G Wireless LAN Controller Switch, the 3750 should 
not run Cisco IOS Releases 12.2(44)SE2 and 12.2(46)SE due to defect CSCsu02630.

To find the software release running on your controller, click Monitor and look at the Software Version 
field under Controller Summary on the controller GUI or enter show sysinfo on the controller CLI.

When you upgrade the controller’s software, the software on the controller’s associated access points is 
also automatically upgraded. When an access point is loading software, each of its LEDs blinks in 
succession. Up to 10 access points can be concurrently upgraded from the controller.
