Supposedly, thare are certain routers that can utilize two separate WAN connections, but the timing has to be established between the two connections in order for the router to negotiate network traffic. Another issue is that both WAN connections must be able to share the same LAN, unless you plan to establish two separate LANs with unique subnets. In the end, too much trouble for the amount of effort involved. I would recommend that you recheck your local area for other internet services. There are ISPs in rural areas that use RF and not hardline copper. Also, cellular service is another option, especially now with most offering unlimited data (for a price). Last ditch effort when all else fails is satellite internet - ugh.
