Issue/Question
When I attempt to connect to WKU-WIRELESS or WKU-SECURE, I get an error message:
The Wi-Fi network "[WKU-WIRELESS or WKU-SECURE]" could not be joined.
Try moving closer to the wireless router. Alternatively, run Wireless Diagnostics to troubleshoot.

If the signal is weak, the error may be accurate. However, if the signal is strong, a system preference file may be corrupted.
