Home Sharing problem in network with repeater

I can't configure a repeater in the same IP range of my main router. I already tried a lot of things, but if I disable the DHCP of my repeater, my router and my repeater don't allow any products to access the wifi.

Now the situation is:

Main router.

IP: 192.168.1.1

Subnet Mask: 255.255.255.0

DHCP: Enable

Repeater.

IP: 192.168.10.1

Subnet Mask: 255.255.255.0

DHCP: Enable

The repeater is getting the networking of main router and the computer with the Itunes and Home Sharing is connected in main router.

When my AppleTV is connected in Repeater, I can't see the library of ITunes. When I connect in main router I can see. My conclusion is that my problem is in IP range. Is that a solution for this problem?

Thanks to anyone that can help me with any solution.
