After a courthouse AP firmware change, Beacons suddenly advertise an unexpected country code and tighter power constraints. What should the WLAN expert validate first from the capture?
Select an answer to reveal the explanation.
Short Explanation
Beacons are the courthouse bulletin board—country, power limits, rates, and security all hang there in the Information Elements. After firmware day, read the board before blaming clients or guessing the GUI is gospel.
Full Explanation
Beacon Information Elements advertise regulatory country/power constraints, supported rates, RSN, and modern PHY capabilities such as HE. A firmware change can alter those advertisements and change client behavior or EIRP limits. Experts validate IE content against the intended profile before broader redesign.
