Can't see device using two routers - Network problem

I’m trying to connect the WDTV Live Streaming to a secondary wifi router within the same workgroup to share files/folders from the main PC to the device. Problem is that Win7 won’t list the WDTV in the same workgroup if both the computer and the device are connected to different routers in the house.

I am pretty sure this is a network issue since I can share folders just fine if both devices are connected to a same router.

My guess is it’s how you’ve got your routers physically connected.

The one that’s NOT connected directly to the internet should either be connfigured as an ACCESS POINT (instead of a router), or physically connected differently if AP configuration isn’t possible.

Like this:

Thanks that solved the problem. I had the main router connected to the wrong ports, now both are in the same subnet.
