What you probably need to look at is iproute2. It has many features one of them being that u can manage links over multiple ISP's.
Using this you could bifercate different traffic over various isp interfaces, or you can have one active and other dormant. In the later case, as soon as one of link goes down the whole traffic shifts to other designated interface.

<snip> Be specific. What fails in your question ( Ethernet card or ISP connection ).
Ethernet Card level failover are build up in driver's itself.
ISP connection faiover can be done via any script also.
