Suppose an end user tried to join a wireless network several minutes ago. The WLC Client View screen shows the client to be in the Association state but not the Authentication state. Which one of the following best describes the client’s current condition?
- The client does not support any of the 802.11 amendments.
- The client has an incorrect pre-shared key.
- Spanning Tree Protocol is blocking the AP’s uplink.
- The client failed to receive an IP address.
Explanation: The client has not yet passed the Authentication stage, so it must have failed to authenticate itself correctly. If the WLAN uses WPA2-Personal, then the client’s pre-shared key could be incorrect.
