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?
