Description dan.g.tob 2016-02-25 19:15:09 UTC
code is currently out of tree
Comment 1 Larry Finger 2016-02-26 15:40:28 UTC
The driver in that tree only works with patches to the kernel that are included in that repo. So far, no one has taken the time to convert the vendor's peculiar code into the form necessary for the driver to meet even the low standards of the staging tree. You will need to clone that repo and build your own driver.
Comment 2 carlos.valin 2016-07-01 01:45:13 UTC
WORKAROUND: sudo apt-get install build-essential linux-headers-generic git
git clone https://github.com/hadess/rtl8723as.git
cd rtl8723as
sudo make install
sudo depmod -a
sudo modprobe r8723bs
Comment 3 Larry Finger 2016-11-09 15:29:29 UTC
I had forgotten that this bug was open. It should be closed as INVALID as it is not really a bug. Thus far, no one has done the work needed to get this really awful code into anything that could be merged, even in staging.

One additional problem is that the driver only works on devices attached to BayTrail processors. Most CherryTrail systems do not recognize the device.

The concern of the OP is real, but not having a driver in the kernel is a deficiency, not a bug.

8723be wifi driver has been merged into staging for 4.12. currently very broken, but this bug is about merging only.

it stopped working starting from 4.14 (regression) https://bugzilla.kernel.org/show_bug.cgi?id=197137
