Wireless DL double slower than UL

Tue Mar 23, 2021 10:37 pm

What can cause trouble such as this: I have a 3x3:3 client connected to wAP AC,
download speed maxes out at ~390Mbps,
while uploading as high as 650-700 Mbps.

The host I'm trying to reach is a 2Gbps wired NAS

wAP AC shows CPU underload when DOWNLOADing to wireless client - ~50% CPU,
and 100% CPU with 600 Mbps when UPLOADing.

And the tragedy is that I need to DOWNLOAD only, 99% of the time......

At what rate (both up and down) is the device connected?
Could you also provide the wAP ac's configuration? /export hide-snesitive file=anynameyoulike

Rates are 877 to 1300 mbps, jumping all the time. But even when they change, IRL throughput stays stable. Generally, rates stay withing MCS7-9 range.
The signal is strong and the connection is stable - CCQ 90-100%, 98% most of the time;
Client signal is -40 dBm all the time, always 3 spatial streams.
Noise floor -100 -120 dBm all the time

It's not connection or radio problem. It feels like artificial cap or glitch, for all I can say.

wAP AC is factory configured, without single settings made by me,
and run by CAPsMAN. Though, while standalone AP Bridge, it behaves the same.

/caps-man configuration
add channel.band=5ghz-n/ac channel.control-channel-width=20mhz channel.tx-power=18 datapath.bridge=bridge datapath.client-to-client-forwarding=yes datapath.local-forwarding=yes disconnect-timeout=10s mode=ap multicast-helper=full name=HIDE SENSITIVE USeLESS rx-chains=0,1,2,3 \
    security.authentication-types=wpa2-psk security.encryption=aes-ccm ssid="" tx-chains=0,1,2,3
add channel.band=2ghz-g/n channel.control-channel-width=20mhz channel.extension-channel=disabled channel.tx-power=12 datapath.bridge=bridge datapath.client-to-client-forwarding=yes datapath.local-forwarding=yes disconnect-timeout=10s mode=ap multicast-helper=full name= \
    rx-chains=0,1,2,3 security.authentication-types=wpa2-psk security.encryption=aes-ccm ssid="" tx-chains=0,1,2,3
add datapath.bridge=bridgeGuest datapath.client-to-client-forwarding=no datapath.local-forwarding=no name= security.authentication-types=wpa2-psk security.encryption=aes-ccm ssid="Guest"
P.S. Maaan, they broke terminal console with this new font for good!
