Is anyone else seeing this? Router is about 4 meters (13 feet) from laptop with no obstructions. Laptop card is Intel BE201.
Flint 2 (GL-MT6000) running OpenWrt 24.10.4 WED is enabled. Wireless setting on router is Width = 160 MHz.

Try to boot some linux like fedora from USB drive and check again. Should be 2400 maybe 1 MCS down both ways and transferring at least half of it.
Are you thinking it might have something to do with the Window's Intel Wi-Fi drivers?

Yeah, try to upgrade them while at it.

Got it ;--)
Please connect to your OpenWrt device using ssh and copy the output of the following commands and post it here using the "Preformatted text </> " button (red circle; this works best in the 'Markdown' composer view in the blue oval):
Remember to redact passwords, VPN keys, MAC addresses and any public IP addresses you may have:
ubus call system board
cat /etc/config/network
cat /etc/config/wireless
cat /etc/config/dhcp
cat /etc/config/firewall
Windows has lots of power management,
On Windows tinker with adapter settings:
Transmit Power to Highest.
Roaming Aggressiveness to Lowest.
Disable/enable Throughput Booster.
Power plan to high performance.
If Windows part doesn't work then try these on Openwrt:
Network > Wireless > Increase wireless operating frequency width to max
as @brada4 said, disable WED temporarily.
The output is in the order requested separated by -----.

disable WED temporarily: are you and @brada4 recommending this for debugging or may it be contributing to the issue?
@brada4 and @AlanDias17
Do my iPhone results also indicate a problem?

Nope, iphone has to be static for nreamforming to stabilize. Put it on the desk and 2nd test will be better.
Correct. I disabled it as requested.
i think openwrt system log when laptop reconnecting is also needed. maybe the wifi card negotiate down the bandwidth or something ? seeing your iphone is doing just fine connecting both rx and tx at 160mhz
Can you try running iperf?

- option channel '13'
+ option channel 'auto'
I’ll make the change, but that’s 2.4 GHz. I have only been looking at the TX/RX at 5 GHz.
I think changing Windows Power Mode to “Best Performance” made a difference. I am now seeing consistent values like:
tx bitrate: 2401.9 MBit/s 160MHz HE-MCS 11 HE-NSS 2 HE-GI 0 HE-DCM 0
rx bitrate: 1921.5 MBit/s 160MHz HE-MCS 9 HE-NSS 2 HE-GI 0 HE-DCM 0
iPhone sitting on my desk for the last 3 hours shows:
tx bitrate: 2401.9 MBit/s 160MHz HE-MCS 11 HE-NSS 2 HE-GI 0 HE-DCM 0
rx bitrate: 1441.3 MBit/s 160MHz HE-MCS 7 HE-NSS 2 HE-GI 0 HE-DCM 0
