how to connect 2 ISPs into 1 dual wan router

Jul 24, 2019 12:14PM PDT


There are 2 buildings. Building A has ISP is AT&T, Building B has ISP is Spectrum. These buildings are connected to each other by VPN.

I want to use AT&T from building A become a backup internet for building B by using failover function, and also Spectrum will become a backup internet for building A. But dual wan router requires these ISPs must be in the same building. Is there any way to do it?

You'll need a few things.

A router that does this and support either from your company IT or the router maker. This failover is not in any known consumer grade router. You find yourself getting into Cisco commercial gear. That is, figure a few grand when done.

At the home router level, failover is not supported. Having a home router usually means you can get Internet from one ISP, the one it is configured to connect to. However, you may be able to network two home routers together to be able to have access to two ISPs from the same network. Please see the below link for more information.
