How to install dhclient

I’m trying to configure a wireless lan, and I need to get the IP from the AP. I tried to use the command dhclient wlan0, but the application is not installed. There is a way to install dhclient or is it other command that can be used to obtain the ip address as well?

Regards

Sorry, the answer is in the http://developer.toradex.com/knowledge-base/wi-fi-(linux)#WiFi_Connection_Bring_Up_BSP_V2x link.

I just use connmanctl and the connection is working fine.
