No matter what i try, uploads are always less than half of the download speed. Sometimes not even a quarter of download speed. Tested with iperf3. I don’t have this issue using a mt7922 on a mini pc with crap antennas.
I have tried this:
Linux:
Openwrt, more than one version.
Frank’s Debian kernel and image. 6.11 and 6.12
Cards:
BE14
MT7925e
Qualcomm QCNCM865
Antennas:
Patch antennas
Antennas that came with the BE14 card
etc.
Wifi6 and 7, etc.
Am i missing something?
am using the latest snapshot from mainline openwrt. speed and performance are acceptable.
testing has been done using wcn6850 as client wifi card.
here are some logs:

Thanks for the report. Nice speeds. What card in the R4? Is that a BE14 or a qualcomm one?
BE14, Qualcomm card is 5g modem (RM520-EU) from quectel
