DHCP server conficts with Linksys router

Hello everyone,

I setup a wireless Linksys(wrt300n)router on our network with DHCP enabled, so employees who connect to it can access the internet.

After a short while, The main DHCP server on our Windows 2003 server shuts down as it detects a conflict.

HOw can I resolve this.
Many thanks
