rtl8723be on Fedora27

[Rákosi Gergely]

Hello,

I'm trying to use rtl8723be wifi on Fedora27 but I still get continuosly
disconnection. The error in the dmesg is "Init MAC failed"
I tried with the following module options too : "fwlps=0 swlps=0" and
the variant of "ant_sel=1 or 2 or 0"
I downloaded the git files from your repo, and do the usual make,make
install, and modprobe stuffs, and then restart the notebook, but I get
the same result.

Thanks your help,
Regards,
Gergely

I know from the E-mail you sent to me privately that you are new to this 
process, thus I am going to give you some pointers. It is important for you to 
give your kernel version. Yes, for devoted Fedora users, saying that you are 
using F27 might be sufficient; however, I am not one of them. You should always 
supply the output of the command 'uname -r'.

On the RTL8723BE, "Init MAC failed" is not the dmesg that is expected from 
either the HP ant_sel problem, or a power-save problem. Incidentally, although 
there are many "fixes" that require modifying the XXps options, the underlying 
cause of that issue was fixed almost one year ago.

The main software component that might be wrong is the firmware. Please find the 
name of the firmware file that is being loaded from the dmesg output. It will be 
rtlwifi/... Once you locate that name, run the command

md5sum /lib/firmware/rtlwifi/xxx

Substitute the actual name for the xxx. Post the output of the md5sum.

Hello Larry,

First of all, thanks your help.
Lets see...here is the kernel version: 4.13.12-300
The machine is an Asus ROG 553VE

The firmware which loading in the dmesg is : rtlwifi/rtl8723befw_36.bin
The output of md5sum is : 1850c1308fbcd95e9f6a7f58ede1e35f

Thanks again,
Best Regards,
Gergely

Could try blacklisting rtlwifi. That way it uses rtl8xxxu.

Hello,

I put in to blacklist the module rtlwifi and rtl8723be, and now I get:
- kde's networkmanager did not recognize wireless devices
- in the messages log there are the following :
"registered new interface driver rtl8xxxu
Bluetooth: hci0: rtl : Direct firmware load for
rtl_bt/rtl8723b_config.bin failed with error -2
- ifconfig give no wireless devices (wlp2s0 or wlan0)

If I blacklist only rtlwifi then load the rtl8723be module like normal.

Thanks,
Geri

Ignore this suggestion. The RTL8723BE is NOT supported by rtl8xxxu. By the way, 
that "u" means that the driver is for USB devices. The "E" at the end of yours 
means PCIe!

That is exactly what is expected. You can ignore that missing 
rtl_bt/rtl8723b_config.bin. The BT part of the RTL8723BE does not need a 
"config.bin". A patch was sent to the BT group to get rid of that message, but 
it seems to be lost somewhere.

In mailing lists like this, top posting is not recommended. Please read 
http://www.idallen.com/topposting.html for a good explanation why top posting is 
not good, particularly for complicated threads.

You have the correct firmware. By the way, the code in 4.13.12 should be better 
that rtlwifi_new. That latter repo is deliberately kept a little bit behind just 
in case there is a regression.

With NO options in the loading, please run the following:

iw dev

You should only see one device. On the "Interface" line, note what your system 
calls the wifi device. Substitute that for the "wlan0" in the next command:

sudo iw dev wlan0 scan | egrep "SSID|signal"

Post that output. In addition, copy the dmesg output to some pastebin and post 
the link as well.

Hello Larry,

I hope this email post format is good, and fit to the rules.
Here is the output:

Scan results seem normal.  Was this scan before disconnect?

Is now v4.13.13.

This is interesting, an H2C command was dropped, but no idea which.

[    9.848052] rtl8723be: error H2C cmd because of Fw download fail!!!

Disconnection happened at boot+440 seconds, associate+429 seconds;

[  439.871033] rtlwifi: AP off, try to reconnect now
[  439.871093] wlp2s0: Connection to AP 4c:5e:0c:c7:fa:e3 lost

I cannot tell what causes disconnect.  I wonder if the same
timing of the problem happens always, or if the timing varies.

Init MAC failed was another 30 seconds later;

[  468.600670] IPv6: ADDRCONF(NETDEV_UP): wlp2s0: link is not ready
[  469.618926] rtl8723be: Init MAC failed

Looking at _rtl8723be_init_mac, there are two false returns; hardware
power on fail, and llt write fail.

Sorry, I don't have rtl8723be hardware.

Rákosi, did any older kernel keep connection?

You might try running "Live CD" of Fedora 26 or Fedora 25, without
installing, to test if unexpected disconnection happens in two older
kernels.  Not for permanent solution, just for easy testing.

I don't have specific advice for Fedora 27, you might ask Fedora
community about that, or use RHBZ.  A quick search finds this old 2013
page;

And now the wireless is working almost 20 hours long, from yesterday
afternoon. I dont know why. Lets check some happening:
- Yesterday I disconnect the charger from laptop, and lay down at the
other room
- I left the laptop more than a hour without interaction, so the system
is going to sleep
- When I push the keyboard the system load up, and everything is working
fine
- The battery almost depleted when I going back to the original room,
and connect the charger

Then nothing changed, and I have a working rtl8723be wifi module. Why ?

Thanks,

I found a workaround! If I power up the laptop, and check the wifi, and
if it is OK, then I close down the screen (thats mean laptop going to
sleep). After I open it, and just using like normal, then the connection
working well for a day, or more.
If I dont do that, then comes up the usual problem.

What ? Anybody have an idea what is it mean, and how ?

Thanks
