Section 3 - Configuration
The DWR-118's multi-WAN feature allows you to set your router to automatically switch to a secondary Internet connection if your primary Internet
connection is lost. Note that you must first specify your primary Internet connection either on the "WAN Service" on page 9 or the wizard on
the page 20 before you can specify a secondary Internet connection. By default, the primary connection is DHCP over Ethernet.
In addition, the router has a function called Load Sharing which allows you to access the Internet over 3G/4G and Ethernet simultaneously, combing
the speeds of both connections for a faster Internet experience.
Failover type: Select Disable, Failover, or Load Sharing.

due to inactivity. An example would be Google's public DNS

servers.
Primary WAN: This will automatically be set to the currently configured Internet
connection type. If Failover has been selected, this will be used as
the only Internet connection for as long as it is functional.
Secondary WAN: This can be set by clicking on Add, the available options will be
shown in the drop down box that appears. If Failover has been
selected, this will be used as the backup connection only.
Click Apply to save your settings, or Refresh to revert to your
previous settings.
