You might investigate the use of "synchronous_dhclient" in /etc/rc.conf:

                 (bool) Set to “YES” to start dhclient(8) synchronously at
                 startup.  This behavior can be overridden on a per-interface
                 basis by replacing the “DHCP” keyword in the
                 ifconfig_⟨interface⟩ variable with “SYNCDHCP” or

FWIW, I use 'synchronous_dhclient="YES"' in my laptop's /etc/rc.conf,
(and have done since 2012/01/26 12:39:23).

Yes, Mr. Trump, your behavior IS a disgrace -- to put it very nicely.
