Automatic Classification
This option is enabled by default so that your router will automatically determine which
programs should have network priority.
Dynamic Fragmentation
This option should be enabled when you have a slow Internet uplink. It helps to reduce
the impact that large low priority network packets can have on more urgent ones by
breaking the large packets into several smaller packets.
Automatic Uplink Speed
When enabled, this option causes the router to automatically measure the useful uplink
bandwidth each time the WAN interface is re-established (after a reboot, for example).
Measured Uplink Speed
This is the uplink speed measured when the WAN interface was last re-established. The
value may be lower than that reported by your ISP as it does not include all of the network
protocol overheads associated with your ISP's network. Typically, this figure will be
between 87% and 91% of the stated uplink speed for xDSL connections and around 5
kbps lower for cable network connections.
Manual Uplink Speed
If Automatic Uplink Speed is disabled, this options allows you to set the uplink speed
manually. Uplink speed is the speed at which data can be transferred from the router to
your ISP. This is determined by your ISP. ISPs often specify speed as a downlink/uplink
pair; for example, 1.5Mbps/284kbps. For this example, you would enter "284".
Alternatively you can test your uplink speed with a service such as www.dslreports.com.
Note however that sites such as DSL Reports, because they do not consider as many
network protocol overheads, will generally note speeds slightly lower than the Measured
Uplink Speed or the ISP rated speed.
Connection Type
By default, the router automatically determines whether the underlying connection is an
xDSL/Frame-relay network or some other connection type (such as cable modem or
Ethernet), and it displays the result as Detected xDSL or Frame Relay Network. If you
have an unusual network connection in which you are actually connected via xDSL but for
which you configure either "Static" or "DHCP" in the WAN settings, setting this option to
xDSL or Other Frame Relay Network ensures that the router will recognize that it needs
to shape traffic slightly differently in order to give the best performance. Choosing xDSL
or Other Frame Relay Network causes the measured uplink speed to be reported
slightly lower than before on such connections, but gives much better results.
Detected xDSL or Frame Relay Network
When Connection Type is set to Auto-detect, the automatically detected connection
type is displayed here.
StreamEngine Rules
A StreamEngine Rule identifies a specific message flow and assigns a priority to that flow. For
most applications, automatic classification will be adequate, and specific StreamEngine Rules
will not be required.
Conflicting rules are not permitted. Conflicting rules are those that share any combination of
source address/port, destination address/port, and protocol. Rejecting conflicting rules ensures
