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.

Larry

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

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...
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.

Thanks,
Gergely
