Routers set up incorrectly?

[natto fire]

I am having troubles setting up shares on our network and I think it is because of the way the routers are configured.

Here is a simple diagram

Group A cannot see the shares or LAN games in Group C, bur can with Group B. Both routers are set up for DHCP, which is not a good idea, right? Also, is it hooked up correct as far as using the uplink on the router for group A and B?

UPDATE: Thanks for all the help so far, but it is time to change the network yet again, and am trying to figure out the best way to do this.

We have been using very poor and expensive radio broadband which is fairly common in such a rural area. The situation is kind of complicated, but we are essentially locked into a contract with this terrible service for 3 more years. DSL has become available here and offers much more for much less, especially since we are about 1 mile from the recently upgraded CO.

Anyhow, to refer to my diagram again which has been updated on where the DSL modem is planned to go, I have a couple ideas.

The one computer in Group C is mine (which is actually separated by a 200 ft ethernet cable from the other computer in group C), and I will be kicking in for the DSL payment so I want to figure the best way to route it to my trailer.

I figured I would disconnect my computer from the router and just put a switch on top of it and move the wire from B<->C router to the switch.
That of course would leave only one client on the radio internet, but he is the only one that pays for it, so maybe that is the best way.

The uplink per-se does not matter in mpsy current hardware (the ports are usually MDX).

However if the second Router is connected to the Router that is on the modem using its WAN port you have two sparate Networks , and the second Router's NAT Firewall shields Groups A & B from C.

If you intentions are to have one cohesive Network the second Router should be used according to this principle.

Ok, thanks. I tried to explain to the people that are using the network that the problem was both routers were functioning as DHCP servers, and that was conflicting. While it is not connected through the WAN it does seem to be functioning as a gateway where the internet works on all computers, but the Local sharing is not working right, and I think both routers having the IP 192.168.1.1 is causing problems.

Here is what you want

Wireless Bridge (ethernet port) -> Linksys Router (WAN port)
Your PCs -> Linksys Router (LAN ports)

Get your Wireless Bridge connected to the RV park WLAN. The wireless bridge should be transparent to your router which means your router should not know about it. It should just pass traffic at the layer two level.

Linksys Router Settings:
Linksys in "Gateway" mode
WAN DHCP
LAN DHCP Server in an address space other than what your RV park address use (like your 192.168.2.x in your example).
LAN address some addres in the 192.168.2.x space (192.168.2.1?)
Gateway on your PCs to use the Linksys Router


This will create a private NATed network like what you want. This is a "double NAT" situation but this should work from what you are requesting if you truly want to keep your private network truly private from the RVers.

Bump for update.
