Share 1 DSL connection with 2 different internal networks

I am looking for a way to be able seperate my current network, ( DSL modem, Firewall Router, Wireless Access Point) into 2 seperate networks for security reasons.  We would like to be able to have a single Internet connection using the DSL modem but then somehow split the internal network in 2.  Would I do this by purchasing another firewall router?
Do I only need to change the subnet mask?
Currently we are using the internal ip range of 192.168.?.? and the subnet mask of 255.255.?.?
Any and all help would be greatly appreciated.

yes.  Just get another firewall/router, configure its WAN port for a static address in the 192.168.x.x range you are using and connect it to one of the LAN ports on the existing system.   Configure the new unit's DHCP to a different range and you should be in business.  If you are going to use wireless on the new range, use a different WEP key and SSID to keep them easily identifiable in "View Wireless Networks".

Thanks for the quick response,
I want to make sure that I understand this correctly.
My firewall router now is connected directly to the dsl modem through its wan port and the internal network I have is using 192.168.?.? with subnet 255.255.?.?, would I now take a second firewall router and configure it for the wan side to be static IP ( this would be an address of the 192.168.?.? with subnet 255.255.?.? which is the other firewall router) connecting it to one of the internal ports?
Then could I configure the internal network of the other firewall router to use the 10.0.?.? ip range and the subnet 255.255.?.? so they would be completely seperate and not be able to see or connect to the other internal network but still be able to share the same Internet dsl connection?
Would this same thing be true for Cable Internet connection?
Thanks again for your assistance.
