7.1 Connection Manager
The router can establish an uplink via either USB or ExpressCard modems. If the primary WAN connection fails the router
will automatically attempt to bring up a new link on another device. This feature is called failover. If Load Balance is
enabled, multiple WAN devices may be plugged in and each may establish a link.
7.1.1 WAN Interfaces
This is a list of the available
interfaces used to access the
internet. You can enable, stop, or
start devices from this section. By
using the priority arrows (the arrows
in the red boxes; these show if you have more than one available interface), you can set the default interface and the
failover order. For other modem configuration options, see Internet
→ Modem Settings.
In the example shown an ExpressCard modem is set as the primary internet source, while a USB modem is attached as a
backup. The ExpressCard modem
is ―Connected‖ while the USB modem is ―Idle.‖
Load Balance: If this is enabled, the router will use multiple WAN interfaces to increase the data transfer throughput by
using any connected WAN interface consecutively. Selecting Load Balance will automatically start the WAN interface and
add it to the pool of WAN interfaces to use for data transfer. Turning off Load Balance for an active WAN interface may
require the user to restart any current browsing session.
