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 High performance, low power Embedded Computing Systems | Toradex Developer Center link.

I just use connmanctl and the connection is working fine.
