The computers attached to the second router can connect to the Internet through the cable to the first router (and through it) as you would like. However, you must understand when you do this, you have created two private networks. The first is the network you had before attaching the second router. It includes all the cables and devices that attach to those cables coming from the "LAN" or inside (or whatever your router calls them) ports of the 1st router. The Internet itself (or your cable or DSL modem) attaches to the Internet In (a.k.a. WAN port or Wide-Area Network port) port of the 1st router. The second network are the cables and the devices attached to the LAN ports of the 2nd router. The 2nd router then is both on the 1st and 2nd networks. It both bridges and separates the two. That's what a router does.

Like any two networks, the IP addresses must be sufficiently different in order for the (2nd) router to decide when it should transfer a packet from one network to the other. In order make sure it can do this, change the network that the 2nd router is using for its LAN addresses to a different one than the 1st router is using.

For example, if the first router's IP addresses start with 192.168.0.xxx, where "xxx" is different for every device attached to the first router's network. The 2nd router's "Internet In" will have an address on the first router's network (e.g., 192.168.0.5). In the configuration for your 2nd router, change the IP address of the LAN (and the DHCP addresses it is serving if you are using it as a DHCP server) to be something like 192.168.2.yyy. Typically, 192.168.2.1 would be the number you would assign as the IP address of the 2nd router's LAN. You'd then set it's DHCP settings to serve some set of address like 192.168.2.2 through 192.168.2.100.

You can always disable the DHCP server on one of the routers, ore use a hub to expand your existing your network. This will eliminate that two network segment issue.
