We have two internet providers, Cable and AT&T. Cable is fast and AT&T is slow. We tried to get a faster service from AT&T but it is not available at our location. So here is the problem. We want a fail over setup so we stay up all the time. If cable only is connected in WAN port 1 to the router we get the fast speed. As soon as we connect AT&T into WAN port 2 the user speed drops to the slow AT&T Speed. Is there a way to always run at the cable speed unless cable is down and AT&T takes over?
