A few questions to figure out the cause of the performance delta: - How do you measure the throughput? - Are you using bridging between cable and wifi? - What is the system load in top while you're running the test? - Please show me the relevant output from /sys/kernel/debug/ieee80211/phy1/netdev:*/stations/*/rc_stats while running a throughput test.
