There's an even simple program called wifi-menu which scans and displays available SSID's in the vicinity.

This creates a profile in the /etc/netctl/ upon successful authentication  connection  with the
 [wiz@Arch-DOC netctl]# cat wlp2s0b1-myrouter
Interface=wlp2s0b1
Connection=wireless
Security=wpa
ESSID=myrouter
IP=dhcp
Key=myp@ssword


[wiz@Arch-DOC ]# netctl start wlp2s0b1-myrouter 

Type iwconfig, and it should listout the active wireless link details.



Now, to enable the wireless interface across restarts/reboots, do the following to ensure it is enabled and loaded

[wiz@Arch-DOC ]# netctl is-enabled wlp2s0b1-myrouter
Failed to get unit file state for netctl@wlp2s0b1\x2dmyrouter.service: No such file or directory

[wiz@Arch-DOC ]# netctl enable wlp2s0b1-myrouter

[wiz@Arch-DOC ]# netctl is-enabled wlp2s0b1-myrouter
