trouble w/ router...

well, got a wireless router. The way our house is set up is:

computer 1: main computer that is downstairs. Cable modem plugged into this computer. This computer runs to switch as well (has two network cards).

my computer: upstairs, also plugs into switch. I access the internet from the downstairs computer.

now, how I hooked up my router is: the same wire that was in my computer, I put in the router's WAN. Then, I hooked up my computer in one of the open ports to the router.

I can access the internet just fine, but I can't see anyone from Network Neighborhood, and no one can see me.

Is everything hooked up right? I mean, I can access the internet, which means that I must be accessing the downstairs computer somehow. But why can't I see any comps over the network???

Did you turn off ICS on PC1?

hmmm.. check the most common setting people tend to overlook....

is file sharing enabled?
are the networked computers under the same "workgroup"?

btw, what like DoPeY5007 mentioned, what os you running?

============================================
my bad, it seems you already had a network up and running before installing the router. what software were you using before to share your internet? windows (ics), sygate ??

So wait...you bought a wireless router and are still using a PC as a router? If you are hooking up the cable from the 2nd NIC of your downstairs computer to the WAN port don't expect to see the downstairs computer. If that is how you set it up then your downstairs computer is the internet and considered a different network so file sharing can't happen.

right... there is pretty much no need for the additional switches (and 2 network cards in your main pc). what kinda router did you get? most routers nowadays come with 4-port switches. if you got one of those, simply plug in the cable from your modem to the wan port (router), and plug in any computers' you want to have internet connection and share files on into any of the 4 ports/switches.

of course you might have to make the necessary settings on your router depending on what brand it is.

The cable modem connects to the WAN jack on the router.

The router probably has 4 ports on it - this acts like a normal switch. Plug all your computers into these ports (if 4 ports aren't enough then you can daisy chain another switch on one of them with a cross over cable).

All computers should see each other.

I suspect the reason your main computer can't see the others is because the NIC you're using on the main system is configured wrong and/or you haven't disabled ICS on it.

I'm going to guess you connected the main system to the Router/AP using the NIC that used to connect to the modem. Since that NIC was configured to automatically detect it's IP, it just got an IP from the DHCP server in the router (same as it got one previously from the modem).

However I'm willing to bet you have other networking features disabled on that NIC (you may not have file sharing working on that NIC).

Also, your 2nd NIC (the one you used to use to share Internet to the rest of the house) is still configured for ICS (to share internet). If you connected that NIC to the router then your other computers would be detecting two DHCP servers which would cause problems.

Disable ICS on that 2nd NIC, and disable the NIC entirely.

Make sure File and Printer Sharing is installed and enabled on the 1st NIC.

Also turn off the firewall on that first NIC if it's enabled.

Hope this helps...
