Just got myself a Banana Pi R4 Lite with WiFi 7 BE14 NIC and after fiddling around with it I got it to work just fine with latest OpenWRT 25.12.4, but one issue that kills all of joy of this great hardware: when I do iperf (or Librespeed) testing on my LAN i get great speeds up to a 1 Gbps over air, but when i go over Speedtest to test my WiFi I get approx 20 Mbits down and 40 Mbits up and I can not wrap my head about why is it behaving like that.
During my troubleshooting I tried:
- all of the Offloading modes and disabling offloading;
- moving WLAN to a different subnet from br-lan;
- all of the above with WED ON and OFF
with no success. I have not yet tried to install ImmortalWRT, I heard it behaves better with Mediatek hardware that Banana Pi and BPI NICs use.
I would appreciate any help, because I was not able to find answers on forums or github (or maybe I was googling it wrong…)
