[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[Peter Ludwig]

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!)

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:

I added the options sugested in rtl8723be.conf

options rtl8723be fwlps=0 swlps=0

But this did not help either.

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[Peter Kabiri]

What worked for me was enabling the MSI parameter (message signal
interupt). I have a lenovo Z50 laptop. My wifi would work with all wifi
laptop manufacturers but i was having a problem with a Lancorm wifi
router at a Hotel I once stayed.

what i did was this. I scrowled to the file "sw.c" in the folder

"/home/peter/rtlwifi_new/rtl8723be"

Then in the sw.c file, I added the variable ".msi_support" (which was
missing) and initiated it to "false" under the data type "rtl_mod_params
rtl8723be_mod_params" i.e

static struct rtl_mod_params rtl8723be_mod_params = {
.sw_crypto = false,
.inactiveps = true,
.swctrl_lps = false,
.fwctrl_lps = true,
.msi_support = false,
};

Since msi_support is by default disabled, we have to appropriately
initialize it as disabled(hence false),

I then complied the code, ie

cd rtl8723be
make clean
sudo make install
sudo modprobe rtl8723be

after that I set the msi parameter to 1, in the file "rtl8723be.conf" which can 
be found under
"/etc/modprobe.d"
i.e
options rtl8723be fwlps=N ips=N swenc=Y msi=1

You may have to reboot the computer and wait after for a couple of
minutes after restarting the browser for the msi to be triggered.

This worked for a lenovo z50. Depending on your pc, you may toggle and
choose instead an msi of 0

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[Jelle]

Hi,

I'm experiencing the same issue as @avirup-das. I have the RTL8723BE on
my HP Stream 11. I verified the wifi works great in Windows (8) so the
internal card is okay.

Using Xubuntu-amd64 15.10 with new installed kernel 4.3.0 (same results
as in kernel 4.2.0)

Wifi does work and the laptop connects to the network, but my wireless
controller reports a very weak signal from my laptop. Ubuntu also
reports a weak signal with connection to the AP. I can only connect to
wifi when sitting next to the AP. (All my other devices can connect fine
from a certain distance from the AP.)

Signal is stable (very near the AP) when sitting in the same place and
there's no interference. Bandwidth/speed is between 1kb/sec and
100kb/sec max.

 # iwlist wlo1 txpower
returns Tx-Power at 20dBm (100mW), so that seems okay.

I've tried;
- Using newest lwfinger git driver: Getting the above results
- With and without the modprobe config options (tried on and off 'ips', 'msi', 
'fwlps' and 'swlps'): "msi:Y" results in no connection, msi:N does give above 
results. No difference setting other options.
- Use ndiswrapper to use Windows drivers for this card: This doesn't change 
anything to the above.

[Avirup Das]

Hi all,

I am very new to Linux and facing similar issue with RTL8723BE on HP-
15AF006AX.

At first, the system couldn't recognize any Wifi network.

Tried the rtlwifi_new. Now, the wifi does connect, but only withing a
range of 1M from router's antenna. The connection drops are very
frequent.

Next i have tried to add 'options rtl8723be fwlps=0 swlps=0' to the
"/etc/modprobe.d/rtl8723be.conf". No luck. The connection keeps
dropping.

I have Ignored the IPv6 settings and checked for the Power Management to
be 'Off'.

Are we expecting this bug to be fixed in near future? Else I might have
move back to Windows.

The line in #78 that ends with modprobe. should continue like this:
modprobe.d/rtl8723be.conf

But you can always just create the file and put this in it:
options rtl8723be fwlps=0 swlps=0

@Thomas, have you tried editing the driver settings as suggested in #78?

Note: there is a line in that post that got split at modprobe.d. It
should read:

Edit the settings for the driver:
echo options rtl8723be fwlps=0 swlps=0 | sudo tee 
/etc/modprobe.d/rtl8723be.conf

[y s]

Can we try to see why the power save drops the connections?

If I try to log debug messages by

   sudo rmmod rtl8723be
   sudo modprobe rtl8723be debug=5

where will I see the debug log? Can I post it here for people to figure
out what's wrong?

@Adam, I can open a new bug, but my problem is disconnecting wifi with
rtl 8723be on 14.04.02. Wouldn't it be a duplicate?

I am just trying to understand how launchpad works. Or did you mean open
a new bug to discuss how to debug the wifi card drivers?

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[Peggys Mouse]

No solution but here's the workaround that finally worked for me...
(Ubuntu 14.014 stock kernel)

Download the latest driver (you might have to install git first):
git clone http://github.com/lwfinger/rtlwifi_new.git

Change into the new directory you just created:
cd rtlwifi_new

Compile and install the new driver:
make
sudo make install

Edit the settings for the driver:
echo options rtl8723be fwlps=0 swlps=0 | sudo tee 
/etc/modprobe.d/rtl8723be.conf

It's probably a good idea to take a look at that file to make sure that
worked. Some people say the swlps=0 part of the command above is
unnecessary. I'm not sure but it doesn't seem to be hurting anything.

Reboot.

For me, the text options rtl8723be fwlps=N ips=N in
/etc/modprobe.d/rtl8723be.conf fixes the problem.

At the core of 3.16 observed permanent disable wi-fi with a periodicity of 
around 20 minutes. Put the kernel version 3.18 but there is a bug on it.
Is used to avoid hang tight wi-fi installed on the router __ hidden access

bug (ineternet disappeared) that was enough to reconnect to avoid rebooting the

After further testing I cannot confirm a fix either by installing kernel 3.18 
nor by installing the latest rtlwifi_new as suggested in #55.
After 20 to 30 minutes of surfing the wifi connection is still shown as active 
in Gnome status, but no data is coming through.

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[Peggys Mouse]

#55 worked for me. Ubuntu 14.04 3.13.0-40-generic. Ran torrents all
night which I haven't been able to do with this laptop's internal wifi
card.

In case others are confused by the mention in that comment about the
kernel headers, I believe you can safely run the following commad to
install them:

sudo apt-get install linux-headers-generic

If they are already installed, it won't hurt anything. Then just follow
with the rest of the commands in #55.

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[dpacmittal]

I have two USB - one is inbuilt my laptop which uses driver rtl8723be, and 
another netgear USB adapter which uses driver rtl8192cu. 
Both of them are dropping the connection. 

I tried #55 and now 8192cu doesn't load at all rendering my USB adapter
useless. rtl8723be seems to be better. Connection drops have become
lesser, although they are still there. And when it happens I can simply
disconnect and reconnect to the wifi. No need to unload and reload the
driver module.

@antonio-tobon

Thank you, but unfortunately, following this suggestion immediately locked up 
the system in a kernel panic.
However, the rtl8723be seemed to work fine after a kernel update a few days 
later. Perhaps there was a slight bug in the version I downloaded and the one 
pushed into the Ubuntu repos had it fixed. All is well now.

[Antonio Tobón]

I found this solution, and worked perfectly on a Lenovo g40-30 so it
should work in other lenovo pc...

quote:

for one time test:

sudo rmmod ideapad_laptop

for working after reboot:

echo blacklist ideapad_laptop | sudo tee -a /etc/modprobe.d
/blacklist-ideapad.conf

found it in: http://askubuntu.com/questions/507470/wifi-not-working-on-
ubuntu-14-04-lenovo-g-50-30/535976#535976

prior to that I re-installed the module, updated the kernel to 3.16, and
none of that worked.

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[Adrien Monteleone]

Having the same issue on a brand new Lenovo G50 with RealTek 8723be on
12.04.5  3.13-35 kernel.

Tried fix in #55 with kernel panic as the result. (locked up system,
flashing caps-lock led)

I also can't seem to set options that are honored by the driver via
/etc/modprob.d/rtl8723be.conf

Is there is a different location for the .conf file I should be setting
those? (I had to create the file as it was, the driver install did not
create one)

I'm not particularly interested in moving to 14.04 or 14.10 as this
isn't my personal machine with the problem, but can upgrade the kernel
if it's supported on lts-trusty. If not, then I'd hope this will work on
14.04 at the least. The owner isn't keen on non-lts releases if they are
avoidable.

Thanks in advance for any assistance.

[Paweł Kowalik]

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.

That's great news.

Does the git repo below = the package with the kernel headers installed?

I.e. are the instructions below everything I need to do to install on a
stock Ubuntu 14.04 with the 3.13 kernel?

Thanks.

I tried that. For kernel 3.13-35 i got a kernel panic.

I tried 3.16 and had to set the following options

options rtl8723be fwlps=0 swlps=0 ips=0
options MSI=1

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[waldguru]

Hello Again,

are there some news?
In actual i found a acceptable pro-forma solution for the WLAN-problem with my 
flex 14-2.
At first a look to my trial-history:
I installed the Kernel 3.16 and later the 3.17 RC 4 manually (you can find some 
tutorials by using google...)
In this two trials I started the rtl8723be-module via 
/etc/modprobe.d/rtl8723be.conf 
with the following content:

options rtl8723be fwlps=0 swlps=0 ips=0

Subjective considered the drop-down-effect is much more better (no
matter with which kernel version) but when i took a ping to my wireless
gateway, I have had a packet-loss from round about 20 percent.

After some investigation i found the tip to deactivate my bluetooth-
device with

rfkill block bluetooth

(you can put this command to /etc/rc.local to have this state after
every reboot)

My actual setup is the kernel 3.17 rc4 with the called module-options.
So i have a packet-loss vom 0 to 1 percent. If i will deactivate the
module-options i have a packet-loss from round about 10 percent.

This is not a clean solution but it makes the handling with the wireless
network much easier in case you don't need the bluetooth-connection.

My actual question is why i cannot use the bluetooth-device
successfully. It doesnt matter if WiFi is activated or deactivated. I
cannot find another bluetooth-devices and my Flex 14-2 cannot be found
by any other bluetooth-device.

Is this problem present by using Windows 8.1? I cannot test it because i
erased my Windows-Partition.

I hope i could help someone with my experiences with this topic.

Greetings, waldguru

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[kozak127]

Driver drops connection, because code for power saving mode can't wake
up the device on lenovo B5400. So, couple months ago, I partially
commented out code that is responsible for putting WiFi card to sleep.

It works almost flawlessly on kernel 3.13-24-generic. It also worked on
kernel 3.11. It is not perfect, but it is pretty usable. Just type:
make, sudo make install, sudo modprobe rtl8723be

Hi, I am using UBuntu 14.04.1 LTS with kernel 3.13.0-32. It comes with the 
Realtek wifi driver . I could run wifi from the live cd image. However 
connection used to drop after sometime . Going through this bug report I tried 
the Fix on #38. It stops the connection drop but there is constant slowing down 
of connection. If I disconnect and reconnect the wifi connection from NM 
applet, connection comes back. See the ping report attached.

I have the same problem with my Lenovo G50-70. I tried #33 but I often
get slow or completely no connection. I am currently using
3.13.0-24-generic. I'm quite new in Xubuntu, help me please.

Used attached firmware from #17 and got connectivity that frequently
dropped.

Tried fix in #38 and so far Wifi seems stable.

Hi, 
Same problem for me. It works good at my home (there is not much devices 
connected) but here I'm in an hotel room for few weeks, there are a lot of 
devices on the AP and the connection doesn't work. Sometimes it works late in 
the night when everyone is sleeping.

Every time I see the same things :
[   46.975771] wlan1: authenticate with 00:3a:99:4c:3b:50
[   46.995592] wlan1: send auth to 00:3a:99:4c:3b:50 (try 1/3)

[braykov]

Hi,
I have tried the same as Sergio and have the same result.
Latest 3.13.0.31 kernel does not fix it.
I also have the options mentioned.
The best I managed is with kernel 3.14 and the driver from github, and
still from time to time the network stops and asks me for a password. If I
enter it, most of the times the network reconnects.
I tried with latest 3.15, but I cannot even compile the driver there. I

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[Sergio Castillo]

I have a Lenovo B5400. With kernel 3.13.0-30 wifi drops from time to
time. I installed the kernel 3.15 but it was worse as I wasn't able to
connect at all.

Is there something I can do?

Tips for RTL8188EE [10ec:8179] and RTL8723BE [10ec:b723] users: those
hardware modules have MSI compatibility issue, on some certain platforms
they work fine with MSI but break connections without MSI, on some other
certain platforms it's opposite. You could try to toggle its module
parameter msi

I have tried the following on several kernels (under 12.04 and 14.04)
and so far it has worked well :

sudo apt-get install linux-headers-generic build-essential git
# needed only if you don't have yet that package
git clone http://github.com/lwfinger/rtl8723be
# needed only if you don't have yet downloaded rtl8723be

cd rtl8723be
git checkout 604aa9058fb9e5bb1cf571c99989d081f8fc8b9
make clean
make
sudo make install
sudo modprobe rtl8723be
echo options rtl8723be fwlps=0 | sudo tee /etc/modprobe.d/rtl8723be.conf

I copied the specified firmware. Restart the computer. 
Successfully connected to wifi, but then nothing works. 

Maximum that was possible - it will connect via ssh to my local server
for a while - then the connection broken.

I finally managed to install the driver with 3.15-rc5-utopic kernel version and 
the rtl8723befw.bin Firmware, but the internet connection is still dropping me 
and enable/disable rtl8723be modprobe doesn't help.
Is there anyone else with the same issue?

[braykov]

Hi,
I've had this problem since november 2013 when I bought the laptop.
With Ubuntu 13.10 at least modprobe and modprobe -r used to work.
With Ubuntu 14.04 the connection drops even more often and only restart helps 
(most of the times).
All drivers I found origin from the released by RealTek. They seem to have a 
bug which no one still cannot find and fix.

I managed to install rtl8723be drivers from GitHub in new Ubuntu 14.04, but I 
still have the problem with connection drop. 
Turning Off/On of WifI/Network or add/remove modprobe rtl8723be is not always 
working.

@Peter, could you please try this very kernel with the firmware I gave
you and feedback?

http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.15-rc5-utopic/

If it works, please boot the -proposed 3.13.0-26 kernel then check
again. Thanks.

[Brad Figg]

This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
trusty' to 'verification-done-trusty'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 1240940] Re: Need support for Realtek Wifi card rtl8723be [10ec:b723]

[Michal]

I have lenovo B5400 with RTL8723BE PCIe Wireless Network Adapter.
I tried  kernel 3.13.0-25.47 from PPA. It has rtl8723be module, but I was not 
able to connect at all.

I am using back 3.13.0-24-generic kernel and with rtl8723be from
https://github.com/lwfinger/rtl8723be.git @ 604aa90 commit.

The bottom line is that committed fix does not work for me.

I have a ThinkPad Edge e540, same problems with 13.10 using the driver from gh. 
Reloading the module works, but not for long.
Seems like a lot of newer Lenovo laptops have this wireless adapter, I couldn't 
order mine with a different one in my country.

[juraj]

https://github.com/lwfinger/rtl8723be - works for B5400. However, it is
necessary to manually declare few constants in the code:

#define IEEE80211_CHAN_NO_IR0
#define REGULATORY_CUSTOM_REG   0
#define REGULATORY_STRICT_REG   0
#define REGULATORY_DISABLE_BEACON_HINTS 0

Put them somewhere, e.g. into wifi.h.

I couldn't find the edit option for my comment, so here is a solution for lost 
Internet connection problem:
sudo modprobe -r rtl8723be
sudo modprobe rtl8723be

This helped me and now I don't have to reboot the machine after Internet
drops.

I have similar issues with Ubuntu 13.04 on Lenovo ThinkPad E540.
The driver from GitHub works, but after some time the connection just dropps 
and I have to reboot. After rebooting the connection is ok until next drop.
