A few questions for you:

1. Who is your ISP? What is the DSL modem model #?

2. It's generally a best practice IMHO to not use the 192.168.x.x and 10.x.x.x on your network. (It can cause a whole mess of problems when connecting to other networks (vpns and such)

Let me know, and we can help you configure your network to run more effectively.
