Ok Blury I see it now. Your actually have two private networks in your screen. Looks like the DSL modem serves an IP to your Linksys which then in turn serves your computer an IP address.
"This" screen is fine. What you need to do now is put your "PC" on a static IP address.
If you use:
IP Address: 192.168.1.2
Default GAteway: 192.168.1.1
Netmask: 255.255.255.0
DNS Servers: ---
You will need to find your DNS servers. To do this go to your dos prompt. Type in the following command "ipconfig /All /batch ipinfo"
This will place all your current information into a text file called ipinfo. Then just type EDIT IPINFO from the prompt and you will see your DNS servers listed in there.
Get your DNS information before setting your static IP on your PC. Because if you dont have DNS servers specified in your properties you will not be able to browse via hostnames.. and thats messy.
Let me know if you need any help on that bud..
