Question
A network administrator recently deployed new Wi-Fi 6E access points in an office and enabled 6GHz coverage. Users report that when they are connected to the new 6GHz SSID, the performance is worse than the 5GHz SSID. The network administrator suspects that there is a source of 6GHz interference in the office. Using the troubleshooting methodology, which of the following actions should the network administrator do next?
- A. Test to see if the changes have improved network performance.
- B. Use a spectrum analyzer and check the 6GHz spectrum. Correct
- C. Document the list of channels that are experiencing interference.
- D. Change the channels being used by the 6GHz radios in the APs.
Explanation
The administrator has already established a theory of probable cause (6 GHz interference), so the next step in the troubleshooting methodology is to test that theory, which is done by scanning the 6 GHz band with a spectrum analyzer. Changing the AP channels would be implementing a fix before the cause is confirmed. Verifying improved performance and documenting findings come after a solution has been implemented.
