Hi
I am joseph from Delta State Nigeria, I'm a field tech, I was ask to go install at a customer end, my experience yesterday was funny, as I keep getting some error message while trying to attach to our AP less than 5KM.
Below are some images of the Error message.
what might be the possible cause?

Hello Joseph,
You may want to do a spectral analysis at the SM location, to see if there is interference in the selected channel.

Do the logs on the AP or SM give any hint as to WHY it's failing? You may need to enable all syslog levels under Configuration-\>System, make sure Info,Notices,Warnings,Errors,Alerts,Emergency are all checked to get the most out of logging.
The errors in the log should help explain. (maybe WPA2 with passphrase mismatch, maybe range limit exceeded, or client limit exceeded, etc)

I would suspect it's just an interference issue - at that signal level, some fairly strong interference could easily be enough to stop it from registering.
