Controller Requirements
Note
The 801 access point (the access point embedded in the 88xW ISR), the 1250 series access
point, and the 1140 series access point have a hardware limitation where beacons can only
be output at intervals that are multiples of 17 milliseconds. When these APs are configured
for a 100-millisecond beacon interval, they transmit beacons every 102 milliseconds.
Similarly, when the beacon interval is configured for 20 milliseconds, these APs transmit
beacons every 17 milliseconds.

Note
Only Cisco Aironet 1200 Series Access Points that contain 802.11g (AIR-MP21G) or
second-generation 802.11a radios (AIR-RM21A or AIR-RM22A) are supported for use with
controller software releases. The AIR-RM20A radio, which was included in early 1200
series access point models, is not supported. To see the type of radio module installed in your
access point, enter this command on the access point: show controller dot11radio n, where
n is the number of the radio (0 or 1).

Software Release Information
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.
