i dont see any detail about the configuration. a iw dev info [ifname]
would be helpfull at least and your hostapd/wpa supplicant config too
for sure.
(remove passwords from config, if required)
the operation mode of your ap is also not clear. is it ht40, vht 80,
channel. all the details
Hi Ben
Much thanks for the help. Switching my TCP congestion control from
cubic (default) to reno resulted in an TCP upstream throughput
increase from 15 Mbps to 175 Mbps. I am getting 283 Mbps with UDP.
283 Mbps still seems low for my setup (4x4 AP with 80 MHz channels,
3x3 STA). I'll try and
Adrian (and anyone else who chimes in),
Thank you for your help. I'm a bit new to this so I really appreciate your
help. Please let me know if enabling any additional debug logs or taking any
additional steps would be helpful. The wireless chip I am using is the AR9888
which is an 802.11ac
If UDP works noticeably better, then you probably need to use a different
TCP congestion control.
Thanks,
Ben

Hi all,
I'm using a QC9880 802.11ac NIC with Ubuntu 14.04 LTS and getting
really low upstream (STA to AP) throughput. The specific NIC is the
Compex WLE900VX.
Testing using iperf3 in TCP mode I cannot achieve much more than 15
Mbps. Downstream throughput is roughly 145 Mbps. I get nearly the
Precise information was not kept on written record :-((
The arguments could depend on the 802.11 mode used. Only one configuration was
tested:
802.11n+a, BW 40 MHz, 1 stream using wired antennas => we can assume the bit
rate was 150 Mbps, we want 30% throughput
So, the iperf was set to UDP,
