[SOLVED] Wifi does not work LFS-8.4

Network does not work. I have built LFS before, but this problem I'm having the first time.

lfs [ ~ ]$ ping google.com

I must note that I use Linux Kernel version 5.0.2

Hi
3 questions
Do you need firmware?
can you ping router?
Can you try an older kernel?

Hi!

1) As you can see, I have a firmware loaded:

[ 5.293826] iwlwifi 0000:03:00.0: loaded firmware version 17.3216344376.0 op_mode iwlmvm

2) I can't ping my router:

lfs [ ~ ]$ ping 192.168.1.1
PING 192.168.1.1 (192.168.1.1): 56 data bytes
ping: sending packet: Network is unreachable

3) I can try, but it will take some time. I will give it a shot.

Now I tried Linux Kernel 4.20.16 and the output is little different:

  
*  Bringing up the wifi0 interface...                                                                                  [  OK  ]

*  Starting wpa_supplicant on the wlan0 interface...[    7.852779] IPv6: ADDRCONF(NETDEV_UP): wlan0: link is not ready [  OK  ]

*  Starting dhcpcd on the wlan0 interface...                                                                           [  OK  ]

I solved the problem. I hade a mistake in wpa_supplicant-2.7. Command:

wpa_passphrase SSID SECRET_PASSWORD > /etc/sysconfig/wpa_supplicant-wifi0.conf

SSID was not correct.
