It is enabled by default, so if you didn't turn it off it should be up,
configured and running.

When it happens, run "/sbin/ifconfig" to get the current status of your
network adapter and also "ip ro" to display the available routes.

That can mean that you have lost all of your network card data (ip,
netmask, gateway...). The above commands will tell.

Then you are using a dhcp server to get all the data for the interface.
You will have to find out why you are losing contact with your dhcp

As first step, you could (as root):
grep -i dhcp /var/log/syslog
