I am connecting to a Buffalo WZR-600DHP running
OpenWrt 18.06.2 r7676-cddd7b4c77 from a Thinkpad T430 (with an Intel Centrino Ultimate-N 6300) running Linux 4.20.
wlan1 on the WZR-600DHP is configured with channel 48, width 40MHz, power auto, WMM Mode enabled.
iw dev wlan0 station dump reports
rx bitrate: 300.0 MBit/s MCS 15 40MHz short GI and
signal avg: -39 dBm. However, speed tests and
iperf3 only report ~50 Mbits/sec. Is there any way to improve the performance to get closer to 300 Mbits/sec?
With debugging enabled on the T430, I see the following messages in
dmesg (which may or may not be relevant):
wlan0: Open BA session requested for XX:XX:XX:XX:XX:XX tid 0 wlan0: BA request denied - HW unavailable for XX:XX:XX:XX:XX:XX tid 0
Suggestions appreciated. Thanks for reading,
