It make it really hard to follow a thread.

Depends on your configuration. Do you use DHCP or static network
configurations? If it is DHCP, I suspect /etc/rc.d/dhclient restart
would do the trick. If it is status:
route add default abc.def.gh.ij
should do the trick. 

Going the other way can be a tiny bit more involved. 'ifconfig wlan0
down' first or 'route delete default' to get rid of the current
static. (Note: wlan0 on stable needs to be replaced with the name of
your wireless interface.)
