we operate 1240 access points in LWAPP mode and with several mobilty groups. Now there is a need to integrate 802.11n access points. As I can see there are 1140 and 1250 series supporting the n-standard.
I understand that 1140 series only supports CAPWAP whereas 1250 series supports CAPWAP and LWAPP. Since I can't mix CAPWAP access points and LWAPP access points in the same mobility group and there is only one mobilty group per module I would need an additional module when buying 1140 series access points?
Is there any way to upgrade 1240 to CAPWAP? Unfortunately, I can't find any hint in the documentation.
The 1240 AP will be running a CAPWAP image when it joins a 5.2. or 6.0 controller. You can have 1140's and 1240's joined to the same 6.0 controller and have all the controllers in the same mobility group.
Firmwares 5.X and 6.X support CAPWAP while 4.X supports LWAPP. The 1140 is supported starting from 22.214.171.124 (hence the reason why the 1140 operates only in CAPWAP).
If you want to operate the 1240 alongside the 1140 and 1250 the common denominator is firmware version 126.96.36.199 or later.
NOTE: 188.8.131.52 and 184.108.40.206 upgrades the firmware of the radio modules of all the AP's it support. Especially the 1250. The radio module's firmware upgrade will allow users to use the 1250 to operate BOTH radios when powered using 15.4w. Very useful!
