|You have a modem/router and a Linksys router.|
The modem router can act as it is.
Figure out the internal IP address of the modem/router.
Ok so lets start to connect the things:
Linksys(WAN) -> (LAN)Modem/Router(WAN) -> Wall Plug (Internet)
Configure the modem and router as follows:
Modem/Router (WAN): leaf as it is, because it can already connect to the internet
Modem/Router (LAN): 192.168.1.1
Linksys Router (WAN) 192.168.1.2 SubNet 255.255.255.0 DNS: 192.168.1.1 (the Modem/Router) default gateway: 192.168.1.1 (also the Modem/Router).
Linksys Router (LAN): 192.168.2.1 SubNet 255.255.255.0 DNS: none default gateway: none
Computers should get the ip address automatically from the Linksys Router.
So a computer might get the following automatically:
ip address: 192.168.2.50
dns server: 192.168.2.1
default gateway: 192.168.2.1
This should work for you.
