• Consider a possible physical security issue.
• Is there power to all devices and are they powered on?

• If connectivity still fails at this point, perhaps something is wrong with the AP or its configuration.
• When the user PC is eliminated as the source of the problem, and the physical status of devices is confirmed, begin investigating the performance of the AP.
• Check the power status of the AP.
