First, a little info on my network:
I have two routers on my network, a Dlink DI-624 at 192.168.0.1 and a Linksys BEFSR41 at 192.168.1.1. The Linksys wan port goes to a client port on the Dlink, it has a static IP of 192.168.0.10.

The problem:
I have a computer running Samba at 192.168.1.20, which is connected to the Linksys router. I can access my shares from the other systems connected to that router, but I can't access them from any computer connected Dlink. I also can't ping from one computer at 192.168.0.102 to my Samba server at 192.168.1.20.

The question:
What do I need to do to allow the computers connected to the Dlink router to have access to my shares?

question?.....why do you need two routers?

To keep the number of long cables to a minimum. The router connected to the modem is at one end of the house and there are 3 computers at the other end of the house. This way there is only one long cable running under the house to worry about. I could do everything wireless, but I like to keep desktops wired.

You don't need additional routers, all you want are switches.

Is there any reason why your two routers can't be on the same subnet?

If you want to keep your current configuration, try changing the subnet masks in the WHOLE network to 255.255.0.0
