I have a cisco wireless controller 4402 with 1020 LWAPP access points install. I did an upgrade of the software to 184.108.40.206 today. I got and error and reset the sytem. Forgetting that the access points may have been updating their software. Now i cannot detect any access points. Is there anyway to get the access point to communicate with the controller again?
"Release Notes for Cisco Wireless LAN Controllers and Lightweight Access Points for Release 220.127.116.11
February 10, 2009
Note Unlike controller software release 18.104.22.168, the 22.214.171.124 release is supported for use in Japan.
These release notes describe open and resolved caveats for software release 126.96.36.199 for Cisco 2100 and 4400 Series Wireless LAN Controllers; Cisco Wireless Services Modules (WiSMs); Cisco Wireless LAN Controller Network Modules; Catalyst 3750G Integrated Wireless LAN Controller Switches; Cisco 3201 Wireless Mobile Interface Cards (WMICs); Cisco Aironet 1100, 1130, 1140, 1200, 1230AG, 1240, 1250, 1300, and AP801 Series Lightweight Access Points; and Cisco Aironet 1130AG, 1240AG, 1522, and 1524 Mesh Access Points, which comprise part of the Cisco Unified Wireless Network (UWN) Solution."
Now, you need to check on the controller.If the current software version is 188.8.131.52 then it will obviously not detect 1000 series APs.If the image on the WLC is something prior to 184.108.40.206 let me know so that we can try some other steps.
