Connecting 5 computers through 2 routers?

I have 5 computers connected through 2 routers. The first router is also a modem and it is giving out 10.1.10.* ip addresses using DHCP. The first modem/router also has 3 computers connected to it. The 4th port is being used to connect to the second router that is giving out 192.168.2.* ip addressing. Sitting behind both routers (192.*.*.* range), I can PING and access both routers. Also behind both routers I can PING all the computers. If I am on the 10.*.*.* range I cannot ping the 192.*.*.* range. I also put each computer under the same workgroup. Both workgroups on each router can't see each other. I can get on the internet on all 5 computers. All I really want to do is set up shares on each computer and be able to access each. If anybody can help me PLEASE HELP ME!!!

you don't need two routers, you need a switch and a router. the way you have this set up, you have set up two separate, private networks, and i don't think that's what you need, from what you have said.

if you got yourself a multiport switch, and plugged your computers into it, you would have a single segment, and everything on your network would have 10.1 address, and you would be able to ping, and connect.

i have done this on many occasions when i needed to set up workrooms at conferences. it works very well.
