[Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]
I know this thread is now two years old but the problem with this
hardware almost drove me nuts ...
I am here on a HP Pavilion Laptop with beatsaudio. No Model Number -
nothing.
The Wifi card is: (in Germany!)
--------------------------------------
lspci -nn | grep -iA2 net
02:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter [10ec:b723]
--------------------------------------
I am now under kernel:
4.4.0-21-generic
-------------------------------------
Before I tried everything I could find to get my wifi up but I do not
even see one spot. So no connection at all. I even cloned git and
compiled the driver - which worked fine.
By the way the BT seems to be fine - although I have not checked cause I
do not need BT.
---------------------------------------------
Here is what I tried:
rfkill list all; hciconfig -a

1: phy0: Wireless LAN

-------------------------------------
I added the options sugested in rtl8723be.conf
options rtl8723be fwlps=0 swlps=0
But this did not help either.

In my disappointment I tried this:
>From https://bugzilla.kernel.org/show_bug.cgi?id=83641#c1
"There is a new version of this driver at GitHub. You will need to have
the package with the kernel headers installed.
git clone http://github.com/lwfinger/rtlwifi_new.git
cd rtlwifi_new
make
sudo make install
This version of the driver will be submitted for inclusion in kernel
3.18. I ran it for 39 hours with no disconnects."
---------------------------------
no errors but no change.
---------------------------------
Checked this link:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1461174
---------------------------------
Then I tried several params and finally this worked somehow.
sudo modprobe -rv rtl8723be
sudo modprobe -v rtl8723be msi=1
I now was able to see wifi networks - hoorayyyy!! :)
---------------------------------------------------------
I then tried to connect to my network - but failed.
I am sitting 1 m next to my router.

Then I changed region to Germany:
echo 'KERNEL=="regulatory*", ACTION=="change", SUBSYSTEM=="platform",
RUN+="/sbin/iw reg set DE"' | sudo tee
/etc/udev/rules.d/regulatory.rules
and then I was able to connect. My options are now:
options rtl8723be fwlps=0 swlps=0 msi=1
Now it runs perfectly! Thanks to all!!
