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
[...]
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:
root@skynet-x2 ~]# iw dev wlp2s0 scan | egrep "SSID|signal"
signal: -46.00 dBm
SSID: SKYNET-X2
[...]
[root@skynet-x2 ~]#
Scan results seem normal. Was this scan before disconnect?
Yes, this command output taken while the connection was OK
Thanks.
And the dmesg output:
https://pastebin.com/iqQSu2hD
Is now v4.13.13.
Yes, thats the upgraded kernel
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.
The timing always changing, never is the same. And I dont realize
the cause at now...
Thanks. I had similar problem with different wireless device.
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?
The oldest kernel is 4.13.9-300.fc27.x86_64 in Fedora 27
installation, but did the same. If you can give advise how, and
what I do, then I'll try it.
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 ?
Who knows? I do not understand why it did not work before the way mine does with
openSUSE!
Larry
