Unlikely you can get it to automatically change. It will use the connection you have set the etherent port to the highest preference and until that port physically goes down it will not change.

Even if you were to use routers or even a fancy dual wan router you have the same problem. Most internet failures everything electrically appears to be operational they just do not pass traffic.

The industry standard solution to this is to run a routing protocol. Since this is actively sending messages it will detect when they stop. Your server can run RIP as well as a couple other routing protocols. So you could detect failures between equipment you control but it is still unlikely the ISP would run a routing protocol. Now of course if you were a large customer the ISP will run a routing protocol called BGP.

The only realistic option I can think of is to try to find a program that does something like ping and if it detects packet loss it uses a script to manipulate the metrics on the nic to force the traffic to the other connection,
