[opensuse-arm] RPi3 poor WiFi performance
Hi everyone, I've just installed Leap 42.3 on my RPi3 last night and had some bad WiFi performance. The SSH connection was nearly unusable. 21/21 packets, 0% loss, min/avg/ewma/max = 409.441/1454.630/1399.198/3025.166 ms At the end simply switching off the power_save option did the trick to have a working connection again. Details got discussed here [1]. #> iw dev wlan0 set power_save off The question is now, if we could disable power saving by default. There is already a patch [2] from the raspberrypi.org guys that is exactly doing that.

+1 from me... Especially when it's a device that's connected to the mains 90% of the time -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

The question is now, if we could disable power saving by default.
Wouldn‘t it make sense to do that in a distro agnostic fashion? For example you could maybe provide a device tree property which disables the power saving mechanisms? Or just patch the upstream driver to detect the rpi3 and do it automatically? Alex
