Why wont my Router Talk to my Switch??

Hello,
I HAVE SETUP MY NETWORK WITH 1 LAYER 3 SWITCH, 2 LAYER SWITCHES AND 1 WIRELESS ROUTER. CREATE VLAN, VTP ON THE NETWORK BUT NOT TALK TO MY ROUTER.

Please be more specific. Which brands and models are you using?
Just a guess, but check the Firewall, the IP-adresses, the cable connection (crossed or noncrossed, try another port and cable).
Can you access the Router directly over the WEB interface?
