In early Intel AX200 drivers (pre-2020), OFDMA uplink was essentially disabled in many OS builds because the driver’s buffer reporting to the access point was too slow, causing the AP to fall back to legacy EDCA. Yes—your "Wi-Fi 6" connection was actually running in 802.11ac mode because of a driver decision .
Here’s an interesting technical piece on the — specifically, how it’s secretly the bottleneck (and savior) of your network performance. The Driver’s Dilemma: Why Your Wi-Fi 6 Adapter Is Smarter Than Your Router Thinks You’ve bought the shiny new 802.11ax adapter. It promises lower latency, higher throughput, and better congestion handling. But plug it in, and… meh. The magic isn’t just in the chipset—it’s in the driver , a piece of software so overlooked it might as well wear an invisibility cloak.
The most underused ax feature is Target Wake Time. Why? Because the driver must coordinate with the AP to set wake intervals that don’t collide with beacons or other STAs. A good driver (like in Apple’s proprietary com.apple.driver.AirPort.BrcmNIC -based ax implementation) can improve battery life by 40–60% in IoT scenarios. A bad driver just ignores TWT entirely.
