There is possibly a setting on your router to address this, but I use the
following dhclient settings which will override whatever your wifi router
decides to send you.

# /etc/dhclient.conf 
# $FreeBSD$
#
#	This file is required by the ISC DHCP client.
#	See ``man 5 dhclient.conf'' for details.
interface "wlan0" {
   send host-name "yourhost.example.org";
   send dhcp-lease-time 864000;
   supersede domain-search "example.org";
   supersede domain-name-servers 9.9.9.9;
   request subnet-mask, broadcast-address, time-offset, routers;
}

A+
