Everything seems ok and slight throughput improvment observed after multiple tests. However, same TX throughput cap at 300 mbps.

Hi everyone,
May be a clue about the 300mbps throughput issue. I used iw dev wlan1 station dump command and it seems that "long preamble" is selected, even if "short preamble" is selected in wireless settings. Could it be the cause of TX throughput limitation ?

Station xx:xx:xx:xx:xx:xx (on wlan1)
inactive time: 10 ms
rx bytes: 3248208593
rx packets: 2494772
tx bytes: 1099823319
tx packets: 201409
tx retries: 21278
tx failed: 0
rx drop misc: 3
signal: -53 [-54, -53, -53, -61] dBm
signal avg: -52 [-54, -52, -53, -59] dBm
tx bitrate: 975.0 MBit/s VHT-MCS 7 80MHz short GI VHT-NSS 3
rx bitrate: 1300.0 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 3
rx duration: 28467523 us
expected throughput: 514.892Mbps
authorized: yes
authenticated: yes
associated: yes
preamble: long
WMM/WME: yes
MFP: no
TDLS peer: no
Powersave: no
Compression: no
DTIM period: 2
beacon interval:100
short slot time:yes
connected time: 624 seconds
Radio Name:



EDIT: I tried to disable "short preamble" in settings and click "apply settings" then enable it and click "apply settings" but it doesn't work. Seems that Long preamble is always on. Is it possible to activate it by command line ?

short preamble is only for IEEE 802.11b Rates

hostap manpage says

Code:
# Short Preamble
# This parameter can be used to enable optional use of short preamble for
# frames sent at 2 Mbps, 5.5 Mbps, and 11 Mbps to improve network performance.
# This applies only to IEEE 802.11b-compatible networks and this should only be
# enabled if the local hardware supports use of short preamble. If any of the
# associated STAs do not support short preamble, use of short preamble will be
# disabled (and enabled when such STAs disassociate) dynamically.
# 0 = do not allow use of short preamble (default)
# 1 = allow use of short preamble
#preamble=1

everything looks normal

you can run the following command on the router

Code:
watch -n 1 iw dev wlan1 station dump


and then start a speedtest, then you see how the TX rate behaves

bitrate, Mhz, MCS and NSS are interesting

you can see quite good if something breaks away (NSS are the spatial streams)

but unfortunately only on the router side, and no idea if it helps

Thank you very much for your help ho1Aetoo, i'll try to do that. I just tried a throughput test on a xiaomi redmi note 8 pro with similar result: Around 310 mbps RX rate and a third of that rate for TX throughput (around 110 mbps).
