Dual Ethernet Problems

I have onboard Ethernet and a secondary Gigabit PCI card in my
system.
My problem is getting both to function together, the gigabit Ethernet is
configured for TCP on my network. I want to use the internal Ethernet
for broadband access.

I can get them to work individually (enabling one disabling the other),
but not both together; there are no TCP conflicts, I just cannot access
the internet with the gigabit card enabled.

Any ideas.
 
It appears you have an IRQ conflict. Check your Device Manager and look at the Resources by type (view menu). Expand the Interrupt request (IRQ) list and check both network devices. Make sure they do not share the same IRQ number. If they are not sharing the same IRQ but still do not function simultaneously, check for other devices that share that same IRQ from either or both network devices. If this still does not resolve your conflict, try updating the drivers of both cards. If that doesn't work, you may want to consider purchasing a different network card.

Hi,

You don't state what you mean by them not working, ie: no network
traffic or are cards are disabled at the hardware level?

Is the problem perhaps that you have set two default gateways, one for
each card? Normally the Internet facing card should have a default
gateway, and the Lan facing card has that setting left blank. If you
have a routed segments on the Lan then you normally need to add a few
static routes.
