Hi I have a problem
The access point is reply when I ping it from WLC. But until know it can't join, even discovery packet isn't arrive in WLC. How this could be? Please help. Need advice.
WLC software version = 184.108.40.206
Management interface address = 192.168.120.10 /24
Model = 5508
Access point software = 1240 Software (C1240-RCVK9W8-M), Version 12.4(21a)JA2, RELEASE SOFTWARE (fc1)
AP Model = cisco AIR-LAP1242G-E-K9
Interface address = 192.168.121.151
Make sure you haven't disabled the option to accept MIC certificates from the AP. See security page on the controller and AP policies. Make sure that MIC is ticked.
Quick question, are there other AP's on this controller already?? If not double check the date and time on the controller to make sure they are right. if no ap's are on this controller also check the AP Policy under security and make sure it will accept Manufacturer Installed Certificates.
you can try to telnet to the AP using it's DHCP address and the default UN: cisco & PW: Cisco
Like Leo mentioned, console into the AP and attach the output of the whole boot up and join process. Like 5 minutes... This will help us understand why the ap is not joining.
