After a municipal library upgrades APs to Wi-Fi 6/7, a capture shows rate and PPDU fields the analyst does not recognize from the old HT/VHT era. What is the expert next step?
Select an answer to reveal the explanation.
Short Explanation
Upgrading the library APs is like switching the bus fleet to a new engine—the old dipstick still fits, but the gauges read different units. When HE/EHT shows up, map those PPDU labels to Wi-Fi 6/7 capabilities instead of calling the capture broken.
Full Explanation
HT, VHT, HE, and EHT describe successive PPDU families with different rate and capability encodings. After a Wi-Fi 6/7 upgrade, unexpected analyzer rate fields usually reflect HE/EHT PHY context rather than random corruption. Experts map captured PHY types to advertised BSS capabilities before changing design or rolling back firmware.
