EWC 17.6.1.13 notebook directly connect to AP. Ping to ip AP OK! NSI key copy-past to CiscoSE.

Hello ArshadsafI tried to connect to the AP, but not successful.:-(  

Thank You, Ric.

Thanks Ric.Indeed, as I myself did not guess. Of course, you can't do this without client support. But then I would be satisfied with a ping from the AP radio interface to the client to exclude the wired network segment.As I understand it in WLC ping...

but then it's a ping WLC to the client. And the losses may not be in the radio. I thought only the radiolink was being tested. Like RF-ping.
