I currently have 3-4402 WLC controllers running 220.127.116.11. We have 45 APs that are spread out between 3 locations. Because I am new to wireless management on Cisco WLCs I need to know if there is a benefit to upgrading to more current code revisions. We currently have a mesh bridge running on two 1030 indoor APs. These are not supported on newer code releases, so I am looking for benefits great enough to warrant purchasing two new bridging APs that are supported on current code revs. Any help/insight would be greatly appreciated. The current code is working fine and we are not doing any Wireless VOIP either.
