Fix: FreeBSD is not able to connect to the network

This article Show archive.org snapshot from the FreeBSD Handbook suggests that editing /etc/rc.conf enables DHCP. Unfortunately, some times this seems not sufficient.

Try a reboot, or start the DHCP client manually with the command

dhclient <network adapter>

You can find a list of network adapters by running ifconfig. Examples are em0 or lo0.
