A Wi-Fi 6 AP in city hall shows high PHY rates and low wireless retries, yet users report slow large transfers. The AP Ethernet uplink is a Fast Ethernet (100 Mbps) switch port. What should the engineer conclude?
Select an answer to reveal the explanation.
Short Explanation
Fancy Wi-Fi into a 100 Mbps straw is a firehose into a garden hose. If the air looks healthy, check and upgrade the Ethernet uplink.
Full Explanation
Modern WLAN PHYs can exceed Fast Ethernet. When wireless retries and MCS look healthy but bulk transfers are slow, inspect the wired backhaul speed, duplex, and switch capacity. Matching the AP to Gigabit or multi-Gig uplinks removes a common non-RF bottleneck; crippling the PHY or tweaking beacons does not fix a saturated 100 Mbps link.
