For Quality of Service QoS , the router supports multiple priority queues to enable a group of home or office users to experience the benefit of smooth network connection of inbound and outbound data without concern of traffic congestion. Actual data throughput will vary. Network conditions and environmental factors, including volume of network traffic, building materials and construction, and network overhead, lower actual data throughput rate.

Environmental factors will adversely affect wireless signal range. This capability allows users to participate in real-time activities online, such as video streaming, online gaming, and real-time audio. Compatible with This eliminates the need to reconfigure every host whenever changes in network topology occur. This provides Internet access to everyone in the office for the price of a single user.

This section provides a brief description of the Router, its associated technologies, and a list of Router features.

The Router is easy to install and use. Standard Ethernet ports are used to connect to computer or other Ethernet devices. The The embedded IEEE The wireless Router supports bit and bit WEP encryption.

Asymmetric Digital Subscriber Line ADSL is a broadband network technology that utilizes standard twisted-pair copper wire telephone lines to enable broadband high-speed digital data transmission and bandwidth hungry applications for business and residential customers. A secure point-to-point connection is established between the user and the central office of the service provider. DSLB advantages include:.

This eliminates the need to reconfigure every host whenever changes in network topology occur. This provides Internet access to everyone in the office for the price of a single user. NAT improves network security in effect by hiding the private network behind one global and visible IP address.

It is compatible with access servers manufactured by major vendors. Using both versions lets the Router to communicate with all RIP enabled devices. If you wish to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN for example to another router or a server or outside your network to an ISP defined default gateway for instance.

Up to 24Mbps downstream bit rate using the G. Any common web browser software can be used to manage the Router. The DSLB complies with or is compatible with the following standards as recognized by their respective agencies. DMT compliant. Place the Router in a location that permits an easy view of the LED indicators on the front panel. All cable connections to the Router are made at the rear panel.

Connect the power adapter here to power on the Router. Use the Reset button to restore the settings to the factory default values in the next chapter for instructions on using the reset button. Insert one end of the Ethernet cable into one of the LAN ports on the back panel of the Router and the other end of the cable to an Ethernet Adapter or available Ethernet port on your computer.

Using a power supply with a different voltage rating will damage the device and void. In order to get the best performance from the wireless component of the Router, you should have some basic understanding of how wireless networks operate. Wireless networking is a relatively new technology and there are more factors to consider when setting up or designing a wireless network than designing a wired network.

Wireless local network as called WI-FI devices such as notebook computers and wireless access points use electromagnetic waves within a broad, unlicensed range of the radio spectrum between 2. A wireless access point AP becomes a base station for the wireless nodes notebook computer for example in its broadcast range.

Often a wireless access point such as the AP embedded in the DSLB, will also provide a connection to a wired network - usually Ethernet - and ultimately an Internet connection. The IEEE These two standards are compatible but use different algorithms for data transmission. However, in order to support different data transmission rates while also be compatible with An access point will send and receive signals within a limited range.

Also, be aware that the radio signals are emitted in all directions giving the access point a spherical operating range. The physical environment in which the AP is operating can have a huge impact on its effectiveness. If you experience low signal strength or slow throughput, consider positioning the Router in a different location. Wireless networks use an SSID Service Set Identifier as means of identifying a group of wireless devices, similar to a domain or subnet.

This allows wireless devices to roam from one AP to another and remain connected. Wireless devices that wish to communicate with each other must use the same SSID. Several access points can be set up using the same SSID so that wireless stations can move from one location to another without losing connection to the wireless network. The embedded wireless access point of the Router operates in Infrastructure mode. It controls network access on the wireless interface in its broadcast area.

It will allow access to the wireless network to devices using the correct SSID after a negotiation process takes place. Many wireless adapters are able to survey or scan the wireless environment for access points. An access point in Infrastructure mode allows wireless devices to survey that network and select an access point with which to associate. In addition, the AP can use different channels frequency bands to avoid unwanted overlap or interfere between control zones of separate APs.

If you are using multiple APs on your network and are experiencing low throughput or significant transmission delay, carefully consider how channels are assigned to the different APs.

Authentication may use an open system or a shared key. Read below for more information on configuring security for the wireless interface. Many physical environmental factors can impact wireless networks.

Radio waves are used to carry the encoded data between devices. These radio transmissions can become degraded due to signal attenuation, multi-path distortion and interference or noise. Attenuation simply means that the strength of the signal weakens with the distance it travels, even if the transmission path is unobstructed.

Multi-path distortion occurs when radio signals bounce off objects like walls, ceilings, metal appliances, etc. This may cause a signal to be duplicated, with each separate yet identical signal arriving at a receiver at different times. Interference and noise from electrical devices such as microwave ovens, fluorescent lights, automobile engines and other radio emitting devices can cause signal degradation.

With all this in mind, choose a location for all your access points including the DSLB.
