Failover
Failover is when two or more WANs are in use, but they are in standby mode. Day to day the internet traffic will go over your primary WAN connection, but in the event of an internet outage, the EdgeRouter, UXG Pro or another router will notice this and route traffic to the secondary WAN. Some routers have more than two WAN ports can do this with more.
To determine when the WAN is down or back up, devices will ping something on the Internet to check. For example, the UXG Pro pings ping.ui.com to check connectivity.
Load balancing
With load-balancing, two or more WAN connections are in use, but instead of one waiting the router will share traffic between them, this is generally used to get more bandwidth into the home or office.
