My Linux box is also available for testing purposes I just tried this on one of my Meson8b boards to see if it's some problem with the MMC controller driver (meson-mx-sdio). Here are my steps: - (boot the board) - ip link set up dev wlan0 - (wait until that finishes, it takes a while because it seems to load the wifi firmware) - iw dev wlan0 scan - (wait a few seconds, then it shows many 2.4GHz wifi networks) - wpa_passphrase MY_24GHz_WIFI_SSID > /tmp/wpa_supplicant_conf - (enter the passphrase and press CTRL-D) - wpa_supplicant -iwlan0 -c/tmp/wpa_supplicant.conf -Dnl80211 & - (wait a couple more seconds for it to connect) - dhcpcd wlan0 - then I ran iperf3, see the attached result - then I ran dmesg | grep -Ei "(rtl8723bs|wlan0)", see the attached result with these commands wifi is working "fine" for me. my definition of fine: it connects to my AP and traffic can flow. transfer speeds are on the low side (with 15Mbit/s and 5Mbit/s) but I have no reference (for example from a vendor kernel) so I can't say if that's to be expected. I am not sure about any "desktop" tools and their behavior because I don't use these. can you please try the steps above and attach the output of the "failing" commands (together with the dmesg output)? Best regards, Martin
