my "problem" is, that the power-save feature of the integrate wlan on Raspberry Pi 3 is enable by default in LibreELEC 7.0.0 and maybe, it's a bug?
Last week a have "upgraded" from Rasperry Pi 2 to Pi 3 and using the same SD-Card with LibreELEC 7.0.0 (which was upgraded from OpenELEC 6.0.3 on Pi 2). But I'm not sure, maybe the following issue is solved in LibreELEc 7.0.0 (with a "fresh" installation, without ballast from OpenELEC or Pi2).
I have found the solution in the OpenELEC forum (OpenELEC Mediacenter - OpenELEC Forum - Raspberry Pi 3 wlan issues (1/1)). But the name of the addon in LibreELEC 7.0.0 is "Network Tools".
The current power-save status of the integrate wlan in the Pi 3 can see with the following command (by default it's activate):
With the command
you can disable it. But it's only temporary. After a restart of LibreELEC it's enable again.
With the script "autostart.sh" (it should contain the last command) you can do this automaticly. You have to put it on the SD-Card (/storage/.config/). Now the power-saving of the integrate wlan on Pi 3 is disable by "default".
But is this a bug? Can somebody confirm this?
For me it's working now and I have no problems, but maybe other users have same problem and that's why I have open this topic.
