Router Modem conflict

I have one machine with 2 network card. One card is connected to
highspeed modem and the other to a router, connected to 2 other computers.

When the router is connected, I cannot go on line. When the router is
disconnected( remove cable), I can go online.

Obviously there is a conflict. Can it be resolved ?

I only need a network printer shared by these 3 machines

I should have added, that the connect, disconnect problem happens on
reboot. If I have connection and then plug in the router cable, I
continue to have connection.

Sounds like you should have the router connected to the highspeed modem
[cable/DSL] and let your network connect via the router. The router would
then assign IP addressing for the networked computers and printer [if a true
network computer].

Should be [if a true network printer].

Don't set a default gateway on the nic attached to the router.

You need to set static routes if you want to access the Internet from
the computers on the other side of the router.

If you post some ip addressing details of your network someone will be
able to help you with it.

Yes, that was my original setup, since last weekend and that is what I
went back to.
I thought that seperate NIC's would be more secure,but that is not the
case. The router is more secure,no more pop-ups on my ZoneAlarm.
I will assuage my fears by installing a RJ45 switchbox, to physically
disconnect the 2 machines when I don't need to print.

Oh okay, then hook the modem to the router, the router to your computers,
BUT disallow Internet access to those other computers and printer [if
necessary]
Use the router's software to setup addressing, one with access to the
Internet, the rest without..
{Oh. is it a NAT? What make and model?}

Here's some help
http://www.hardwaresecrets.com/article/246 - How to build a small network
with a broadband router
http://www.hardwaresecrets.com/article/246/6 - Router
Configuration -Advanced setup


Additional protection can be applied by the software firewall [you still
should run one on the Internet access computer regardless of the
router/NAT], by disallowing the other networked computers any Internet
access [local network addressing ONLY]. Generally the firewall should be
installed AFTER the network has been configured, and MOST will *discover*
the two [Internet allowed and non] networks and set up or allow that in
their configurations.
ALSO NOTE: The Internet accessing computer MUST be running Anti-Virus and
other protection or it WILL contaminate the second network.

If/when you want to finalize the networks, modify the HOSTS file
accordingly.

Here's a web page with a lot of networking links and some basic help if the
above doesn't *click*.
