Cisco Cisco 2106 Wireless LAN Controller

You can install this software release on the following Cisco Wireless LAN controller platforms: 2100 
series, 4400 series and Wireless Service Module (WiSM) for the Catalyst 6500 and 7600.

You must install release 4.1.190.5 or 4.1.191.24M to operate the 1522 mesh access point in your 
mesh network. Release 4.1.192.22M is required for the 1524 mesh access point.

Release 4.2.x and earlier 4.1.x releases will not support 1520 series mesh access points.

A 1522 mesh access point operating with release 4.1.190.5 is only supported in the US and 
Canada. 

Release 4.1.191.24M (and later) provides international support for 1522s, 1240s, and 1130s and 
support for the UNI-2 band in the US.

If a 1522 mesh access point is operating in a network, and you downgrade the software release 
within your network to a non-mesh release, the 1522 will not reconnect and might become 
stranded.

If 1522s are going to be installed in a mesh network that is also operating with 1510s, then note the 
following:

The network must first be upgraded to a version of 4.1.190.5 or 4.1.191.24M.

All 1510s must be upgraded to the new mesh release and associated with the controller (joined) 
before any 1520s can be added to the network.

A 1522 should not be added to the network until release 4.1.190.5 or 4.1.191.24M is running on 
the network to ensure proper communication between 1510s and 1522s.

Mobility groups functionality is supported when operating with 4.1.190.5 or 4.1.191.24M and 
all 4.1.x versions of non-mesh controller software.

A 1510 can be a parent to a 1522 mesh access point in release 4.1.191.24M; however, in release 
4.1.190.5 the 1510 can only be a child to a 1522.

Upgrading to 4.1.191.24M or later provides full interoperability between 1510s and 1522s. 
Release 4.1.190.5 does not provide full interoperability. Refer to the 

 for upgrade path specifics.

If 1524s are going to be installed in a mesh network, then note the following:

Release 4.1.192.22M is required for the 1524 mesh access point.

A 1524 is only supported in the -A regulatory domain in release 4.1.192.22M. This includes the 
following countries: Argentina, Brazil, Canada, Chile, Paraguay, Puerto Rico, United States and 
Venezuela.

If you are operating with indoor and outdoor access points in your mesh network, then note the 
following:

Series 1130 and 1240 indoor access points can operate as mesh access points.

All other indoor access points (excluding 1250) operate as standard, non-mesh access points.
