Hi AP can ping the WLC with ver 8.10. But cannot join it. Please see below message from the AP. Cisco Matrix shows it should join wlc. The new AP ios version is 8.9.100 when using command show version, Maybe I need to upgrade ios ver for the AP. Based on the below Table 6, do you think if 15.3- can be used? Anyone can help to understand if this is correct way? Thank you
