There are some high-level programs, like wicd-curses.
Otherwise, I can tell you that it's a problem you'll solve
once and not have to worry about ever again.

Here's a good tutorial, 8 steps, but if the gumball comes
out you can be happy! I list the steps below.

The page explains more, but this summary comes at the end.
You should probably become root for this, e.g. sudo su.

1. See what your wireless device is:

root at kali:~# iw dev

2. Assuming it is wlan0, bring up that interface:

root at kali:~# ip link set wlan0 up

3. Look for wireless access point:

root at kali:~# iw wlan0 scan

4. Put the access point and passphrase into the config file:

root at kali:~# wpa_passphrase blackMOREOps >> /etc/wpa_supplicant.conf

5. Connect to the access point:

root at kali:~# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf

6. Check that you are connected:

root at kali:~# iw wlan0 link

7. Ask for an IP address (I added the first command, to kill
existing dhclient processes).

root at kali:~# dhclient -x
root at kali:~# dhclient wlan0

8. Check your internet connectivity:

root at kali:~# ping 8.8.8.8

9. That is usually enough, but the article provides a
command to set a default route. 

root at kali:~# ip route add default via 10.0.0.138 dev wlan0

I usually just make sure that ethernet interface is turned off:

root at kali:~# ifconfig eth0 down

Cheers, hope this helps.
