[SOLVED] No internet after connecting: connect: Network is unreachable

I have TP-Link TL-WN722N. I am unable to set the wifi interface up.

[thyrst@melone ~]$ ifconfig
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10<host>

        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 0  bytes 0 (0.0 B)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

[thyrst@melone ~]$ sudo ip link set wlp0s20u5 up
[thyrst@melone ~]$ ip a

Wifi-menu shows me all my wifi spots and let me "connect". However the Internet is no available and netctl is unable to start a service.

[thyrst@melone ~]$ ping google.com
ping: google.com: Name or service not known
[thyrst@melone ~]$ ping 192.0.0.1 # router
connect: Network is unreachable
[thyrst@melone ~]$ sudo netctl is-enabled wlp0s20u5-Homewifi2
enabled
[thyrst@melone ~]$ sudo netctl is-active wlp0s20u5-Homewifi2
failed
[thyrst@melone ~]$ sudo netctl start wlp0s20u5-Homewifi2
Job for netctl@wlp0s20u5\x2dHomewifi2.service failed because the control process exited with error code.
See "systemctl status "netctl@wlp0s20u5\\x2dHomewifi2.service"" and "journalctl -xe" for details.

Output of `journalctl -xe`:

Re: [SOLVED] No internet after connecting: connect: Network is unreachable

Tried manually setup connection:

[thyrst@melone ~]$ sudo wpa_supplicant -Dwext -i wlp0s20u5 -c /etc/wpa_supplicant.conf &
[thyrst@melone ~]$ sudo dhcpcd wlp0s20u5

Works. So, the problem was in wifi-menu.
