i'm trying to upgrade a autonomous ap AP-AIR1242AG to lightweight, but evertime i start the tool the process is stopped, because the the tool can't reach the controller. The Tool recommands that i should permit Telnet, but it is allready permitted.
i can reach the management interface by ping, but anything else (web, ssh, telnet) doesnt work
the ap has the the version 12.3(7)JA1
controller (wlc 5508) 220.127.116.11
Upgrade Tool 3.4
Can anyone help me to solve this problem?
