I use Funtoo Linux, clone of Gentoo with git instead of rsync and some bug-fixes (as I read).

I've installed LXDE desktop, NetworkManager but the applet does not connect when I type Wi-Fi password. So I need to connect in command line to continue installation and configuration.

Here it is the instruction: How to conect wi-fi network without using GUI?

It does not work, giving this:

# ifconfig wlan0
wlan0: flags=4099<UP,BROADCAST,MULTICAST> mtu 1500
...
# wpa_passphrase WIFI222 20172017 > /etc/wpa_supplicant.conf
# cat /etc/wpa_supplicant.conf
network=
 ssid="WIFI222"
 #psk="20172017"
 psk=7.it975ot8o686f8fo86ff...


# wpa_supplicant -B -iwlan0 -c/etc/wpa_supplicant.conf -Dwext && dhclient wlan0

# ping -c 3 www.stackexchange.com
ping: unknown host www.stackexchange.com

I have dhcpcd in rc-update, wlan0 is up, interface is not blocked. But this turn is unsuccessful too:

Nmcli does not help:

Error: Timeout 90 sec expired.

My other notebook funtoo+ xfce is connected to this network with nm-applet and I can see network has security WPA/WPA2. I just want to connect and install nm-applet on LXDE.

Please, what is not working ?

I don't know exactly what goes wrong in your setup, but at least do the testing in steps. Trying to do everything at once doesn't help in figuring out where the problem is.

So.

1) Test that Wifi is working and you can see WIFI222:

# iw wlan0 scan

2) Add control interface to /etc/wpa_supplicant.conf:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev

network=
 ssid="WIFI222"
 psk="your_wlan_key"

Adapt the path and group to your system, I don't know what Funtoo uses.

3) Start wpa_supplicant in an extra terminal window in foreground, so you can see messages, and uses the nl80211 driver (nearly all modern adapters use this, you didn't say what adapter you have ...).

wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -Dnl80211,wext

4) Use wpa_cli to see what's going on:

# wpa_cli list_networks

should show the networks from the config file,

# wpa_cli status

shows the current status, and

# wpa_cli help | less

shows you other commands.

If you see wpa_state=COMPLETED, then you can run dhclient and try to ping.
