CWT Troubleshooting & Maintenance Procedures 2

Question 1

A wireless client shows strong signal strength but experiences frequent disconnections. What should you check first?

Accepted Answer

Check for RF interference sources near the client

Answer

Frequent disconnections with strong signal often indicate RF interference rather than signal strength issues.

Question 2

During maintenance, you discover an AP's firmware is two major versions behind. What is the recommended action?

Accepted Answer

Review release notes, test in a lab environment, then upgrade during a maintenance window

Answer

Best practice is to review release notes for breaking changes, validate in a lab, and schedule upgrades during low-traffic windows.

Question 3

A site survey report shows a persistent -85 dBm noise floor in the 5 GHz band in one area. What does this indicate?

Accepted Answer

A significant source of co-channel or adjacent-channel interference

Answer

A noise floor of -85 dBm in 5 GHz is elevated and suggests a significant interference source degrading SNR.

Question 4

Users report slow Wi-Fi speeds only during business hours. Which troubleshooting step is most appropriate?

Accepted Answer

Analyze channel utilization and client count during peak hours

Answer

Time-correlated slowdowns point to capacity issues, so analyzing channel utilization and concurrent client load during peak hours is the right first step.

Question 5

After replacing a failed AP, roaming clients do not reconnect to the new AP. The most likely cause is:

Accepted Answer

The replacement AP is using a different SSID profile

Answer

If the SSID profile or WLAN configuration on the replacement AP does not match the rest of the network, clients will not associate.
