Hi,
I haven't encountered this problem before. On my WLC 2504 I've tried now software versions 8.0.100.0, 7.6.130.0 and 7.4.121.0 (as per recommendation from other supportforum-posts), but still get this debug error when I'm trying to join ap models 1142 and 2602:
(Cisco Controller) >debug capwap errors enable

Does anyone know what is failing here? Surely the ap's should be "known" in these software versions?
