Network Problems

I have a quick question. I had my Ark Linux machine set up and
working. Then we moved to a new house and now I can get the Ark Linux
machine to connect to the Internet. I have tested the connection with
my windows machine. I mainly would just like to reset the network
settings because I think I just got something messed up.

Is there a quick and easy way to reset the network settings, and can
someone suggest a good web site that can help me debug this?

Thanks

Using: Ark Linux 1.0.0 alpha 12 (will upgrade once I get a Internet connection)
