router has no wan port can I still hook it up to a switch?

[Onceler]

I bought this router thinking I was going to be able to have it work with a switch,have been using it for at least six months bought the switch too.I just looked at the back of the router and no WAN port
will I be able just to connect the switch to my router through one of the ports on it
my router is a dlink dir-655

the WAN port is what connects to your cable/dsl modem, looking at the pics on dlinks site, its the jack smack dab in the middle on the back.
the switch (the remaining 4 ports) is what you use to connect to another switch.
