But it does not describe AP2800. please help me check.
3/Factory reset.
result: AP still not working
4/Change AP version. (8.3 & 8.5)
result: AP still not working
5/Try to register a different version of WLC. (8.3 & 8.5)
Result:AP still not working
6/Decode AP corefile, And i tired to did topic for similar case/defect. I found similar SR: 689055350 There are many defects, and this SR did not solve the problem.
Initializing decoder...
