Clients with High Wi-Fi Security Key-Exchange Failures

The Clients had excessive Wi-Fi security key-exchange failures insight can be accessed from the Global, Site, Access Points, and Clients context. This insight provides information on excessive Wi-FiWi-Fi is a technology that allows electronic devices to connect to a WLAN network, mainly using the 2.4 GHz and 5 GHz radio bands. Wi-Fi can apply to products that use any 802.11 standard. security key-exchange failures observed in the network. When this failure occurs, users connecting to Wi-Fi using PSKPre-shared key. A unique shared secret that was previously shared between two parties by using a secure channel. This is used with WPA security, which requires the owner of a network to provide a passphrase to users for network access. or 802.1x authentication, experience higher EAPOL Key exchange failures. This insight is categorized under connectivity since the users are unable to connect to the WiFi network. This insight displays the following information:

• Insight Summary
• Time Series Graph
• Cards

Insight Summary

The insight summary provides the following details:

• Reason—Displays the possible causes of Wi-Fi security key-exchange failure in the network.
• Recommendation—Displays the possible recommendation against each failure to resolve the same.
• Failures—Displays the exact number and percentage of failures that occurred against each failure reason.

Time Series Graph

This time series bar graph displays the number of Wi-Fi security key-exchange failures that occurred in the network during the selected time period. You can hover your mouse on each bar graph to see the exact number of failures.

Cards

The cards vary based on the context that you access the insight from. Click one of the cards to view further details:
