Can I use the WiSM module with a Cisco Integrated Services Router (ISR)?
A. No. Cisco WiSM cannot be installed on Cisco ISRs. They are compatible only with the Cisco Catalyst 6500 series switch and a Cisco Catalyst 6500 Supervisor Engine 720 (all Supervisor Engine 720 versions are supported). .The WiSM is also supported on Cisco 7600 routers that run only Cisco IOSĀ® Software Release 12.2(18)SXF5. You can install the wireless LAN controller module (WLCM) on the Cisco ISRs. Refer to the Cisco WLAN Controller Network Module Feature Guide for more information on the WLCM.
