[. . . ] BarricadeTM N Draft 11n Wireless 4-port Broadband Router SMCWBR14-N2 LIMITED WARRANTY Limited Warranty Statement: SMC Networks, Inc. ("SMC") warrants its products to be free from defects in workmanship and materials, under normal use and service, for the applicable warranty term. All SMC products carry a standard 90-day limited warranty from the date of purchase from SMC or its Authorized Reseller. SMC may, at its own discretion, repair or replace any product not operating as warranted with a similar or functionally equivalent product, during the applicable warranty term. [. . . ] 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. 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 those that share any combination of source address/port, destination address/port, and protocol. Rejecting conflicting rules ensures 32 that every flow defined in a rule receives the expected priority and avoids indeterminate prioritization that could reduce QoS effectiveness. Name Create a name for the rule that is meaningful to you. Priority The priority of the message flow is entered here -- 1 receives the highest priority (most urgent) and 255 receives the lowest priority (least urgent). Flows that are not prioritized by any rule receive lowest priority. Protocol The protocol used by the messages. The common choices can be selected from the drop-down menu.
