CONNECTION MANAGER
The Connection Manager is used to manage the various WAN interfaces you have available on your router. WAN
interface types (Ethernet, modems) are prioritized in connection preference and failover order (with the top of the list
being highest priority).
This is a list of the available interfaces used to access the Internet. You can enable, stop, or start devices from this
section. Drag the priority icon ( ) up or down to set the interface the router uses by default and the order that it
allows failover.
WAN INTERFACE PROFILES & PRIORITY
Availability Key
Enable Load Balance
On Demand
WAN Verify Data Usage
FailbackStandby
STANDBY
Standby is used to decrease failover time from one WAN interface to another. When Standby is enabled for a WAN
prole or interface, the relevant interfaces are kept in a connected-but-idle (minimal, non-routed trac) state. When
the current WAN connection is disrupted, the trac will failover to the next priority WAN. If that interface is on
Standby, the connection is already established and failover will take much less time.
Note that the current connected interface(s) is/are indicated by a green connection state. For interfaces on Standby,
the interface is indicated by a yellow connection state. If the interface is indicated in red, the interface is not currently
connected or in Standby.
Standby is used to enable faster failover times only. If you want to manage trac to a specic WAN interface, you
will need to use WAN Anity. If WAN Anity is enabled for a particular prole or interface, do not enable Standby for
that prole or interface as the failover results may vary and be unexpected.

User Manual /CBA850 8/25/16
ON DEMAND
Typically, modem connections are not always on.
When the On Demand mode is selected a connection
to the Internet is made as needed. When On
Demand is not selected a connection to the Internet
is always maintained.
WAN VERIFY
If this is enabled, the router will check that the highest priority active WAN interface can get to the Internet even if
the WAN connection is not actively being used. If the interface goes down, the router will switch to the next highest
priority interface available. If this is not selected, the router will still failover to the next highest priority interface but
only after the user has attempted to get out to the Internet and failed.
Idle Check Interval: The amount of time between each check. (Default: 30 seconds. Range: 10-3600 seconds.)
Monitor while connected: (Default: O) Select from the following dropdown options:
• Passive DNS (modem only): The router will take no action until data is detected that is destined for the WAN.
LOAD BALANCE
To enable Load Balancing, select the check box for each desired
device. 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 o Load
Balance for an active WAN interface may require the user to
restart any current browsing session.
From WAN Management, select the Load Balance Algorithm from
the following dropdown options:
• Round-Robin: Evenly distribute each session to the available WAN connections.
• Rate: Distribute load based on the current upload and download rates. A WAN device’s upload and download
bandwidth values can be set in Internet > Connection Manager.
• Spillover: This was the default algorithm in older (version 3) rmware. Load is always given to devices with the
most available bandwidth. The estimated bandwidth rate is based on a combination of the upload and download
conguration values and the observed capabilities of the device.
• Data Usage: This mode works in concert with the Data Usage feature (Internet > Data Usage).
The router will make a best eort to keep data usage between interfaces at a similar percentage of the assigned data
cap in the data usage rule for each interface, rather than distributing sessions based solely on bandwidth. For proper
functioning you need to create data usage rules for each WAN device you will be load balancing. Make certain to select
the “Use with Load Balancing” checkbox in the data usage rule editor.

User Manual /CBA850 8/25/16
When this data is detected, the data will be
sent and the router will check for received
data for two seconds. If no data is received the
router behaves as described below under Active
DNS.
• Active DNS (modem only): A DNS request will be
sent to the DNS servers. If no data is received,
the DNS request will be retried four times at
ve-second intervals. (The rst two requests
will be directed at the Primary DNS server and
the second two requests will be directed at
the Secondary DNS server.) If still no data is
received, the device will be disconnected and
failover will occur.
• Active Ping: A ping request will be sent to the Ping Target. If no data is received, the ping request will be retried
four times at ve-second intervals. If still no data is received, the device will be disconnected and failover will
occur. When “Active Ping” is selected, the next line gives an estimate of data usage in this form: “Active Ping
could use as much as 9.3 MB of data per month.” This amount depends on the Idle Check Interval.
• O: Once the link is established the router takes no action to verify that it is still up.
FAILBACK
This is used to congure failback, which is the ability to go back to a higher priority WAN interface if it regains
connection to its network.
Select the Failback Mode from the following
options:
• Usage
• Time
• Disabled
Usage Threshold: Fail back based on the amount
of data passed over time. This is a good setting
for when you have a dual-mode EVDO/WiMAX
modem and you are going in and out of WiMAX
coverage. If the router has failed over to EVDO it
will wait until you have low data usage before bringing down the EVDO connection to check if a WiMAX connection can
be made.
• High (Rate: 80 KB/s. Time Period: 30 seconds.)
• Normal (Rate: 20 KB/s. Time Period: 90 seconds.)
• Low (Rate: 10 KB/s. Time Period: 240 seconds.)
• Custom (Rate range: 1-100 KB/s. Time Period range: 10-300 seconds.)
Time: Fail back only after a set period of time. (Default: 90 seconds. Range: 10-300 seconds.) This is a good setting if
you have a primary wired WAN connection and only use a modem for failover when your wired connection goes down.
This ensures that the higher priority interface has remained online for a set period of time before it becomes active
(in case the connection is dropping in and out, for example).

DATA USAGE
Data Usage displays upload and download trac for each LAN client. Check Monitor Monthly (or Weekly or Daily)
Usage to begin tracking this information. This data is not retained between router reboots.
For Monthly and Weekly you are able to specify the day to start each cycle (e.g. the 1st or Tuesday, respectively).
Usage Cap: Enter a Cap amount in Megabytes. 1024
Megabyte is equal to 1 Gigabyte.
Use with Load Balancing: When checked, the Load
Balancing feature is allowed to use the thresholds and
metrics of this rule when making balance decisions. This
causes Load Balancing to spread the data usage between
interfaces according to the assigned usage rather than
bandwidth. This is a best eort to keep all interfaces with
these rules at a similar percentage utilization of data (e.g.
10%, 50%, 90%) as the cycle progresses, rather than quickly
using 100% of a fast 1GB capped interface while using only
a fraction of a slow 10GB capped interface, thus leaving
the rest of the cycle with only the slow interface. The Data
Usage algorithm on the WAN Anity/Load Balancing page
must be selected or this checkbox has no eect.
Shutdown on Cap: When checked, the WAN device will
shutdown when the assigned usage is reached. A cycle
reset or a rule deletion will re-enable the device.
Alert on Cap: An email alert will be generated and sent when the assigned data cap is reached. NOTE: The SMTP mail
server must be congured in System > Device Alerts.
Custom Alerts: Check to enable custom alerts at specied percentage of
usage cap.
Custom Alert Percentages: Example: “50,80,90,110” (values can exceed
100%) (Triggers alerts when 50, 80, 90, 110% of usage cap is used)
NOTE: To enable data usage, check Data Usage Enabled from WAN
Management.
Disabled: Deactivate failback mode.
Immediate Mode: Fail back immediately whenever a higher priority interface is plugged in or when there is a priority
change. Immediate failback returns you to the use of your preferred Internet source more quickly which may have
advantages such as reducing the cost of a failover data plan, but it may cause more interruptions in your network than
Usage or Time modes.
