There are 5 PCs at home that I am trying to connect to our LAN. Two were recently added requiring an additional router. I have uplinked the second router and thee WAN works fine, but of course, my network is now segmented. LAN 1 uses 192.168.1.0 and LAN 2, 192.168.2.0, and the range of addresses have been added to the firewall settings on the respective PCs.

Without having to install NICs on all the units, how can I get the PCs to see each other across both networks?

Needless to say, this is important for printer sharing and so on.

Thanks in advance for your help.

I have not fully understood your problem yet, could you be more specific please. Maybe just a couple of lines in routers' config will be enough.

Return the second router. What you should do is buy a switch with enough ports. Connect all five computers and your first router connected to the switch. It sounds like this is more complicated than it needs to be.

I agree with Acattr suggestion. If you want comps to share stuff between each other, dump the router.

The basic function of a router is used to break up a large network into smaller [supposed to be more manageable] networks. Since you only have a total of 7 PCs on a 253 host supportable subnet having another router seems "to complicated" [ private class C 192.168.X/24 addressing provides 254 possible hosts on that single subnet[I'll use the term devices to clarify what a host means]. That means that you still have 247 hosts you can get an address for on that single subnet. If you want hosts on 1 subnet to access resources on another subnet, you have to have something [like an application, maybe http or FTP or web printing] that allows you remote access.

Thanks a bunch for the imput. Now I know what to do if I ever want to experiment with different subnets ;)

Agreed...the 1st router is all you need as it is already sharing your internet connection which is basicly what a "home" router is for. All you need to add is a switch. Even a 5 port switch would work if you have 4 ports available on the router. Just connect the switch to an open port on the router(uplink on switch if its designated)and connect your PC or other devices to the open ports on the switch or router.

If you insist on using the 2 router setup you can add "pointers" or routes on each router config to point to the other router. This however is slightly more complicated than adding a switch in place of the 2nd router.
