63 Parameter Description Authentication Type There are three authentication types: "Open System", "Shared Key" and "Auto". Open System: Open System authentication is not required to be successful while a client may decline to authenticate with any particular other client. Shared Key: Shared Key is only available if the WEP option is implemented. Shared Key authentication supports authentication of clients as either a member of those who know a shared secret key or a member of those who do not. IEEE 802.11 Shared Key authentication accomplishes this without the need to transmit the secret key in clear. Requiring the use of the
64 WEP privacy mechanism. Auto: Auto is the default authentication algorithm. It will change its authentication type automatically to fulfill client‟s requirement. Fragmentation Threshold Fragment Threshold specifies the maximum size of packet during the fragmentation of data to be transmitted. If you set this value too low, it will result in bad performance. Enter a value from 256 to 2346. RTS Threshold This value should remain at its default setting of 2347. Should you encounter inconsistent data flow, only minor modifications are recommended. If a network packet is smaller than the preset “RTS threshold” size, the RTS/CTS mechanism will not be enabled. The wireless router sends Request to Send (RTS) frames to a particular receiving station and negotiates the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS) frame to acknowledge the right to begin transmission. Beacon Interval The interval of time that this wireless router broadcast a beacon. Beacon is used to synchronize the wireless network. The range for the beacon period is between 20 and 1024 with a default value of 100 (milliseconds). Data Rate The rate of data transmission should be set depending on the speed of your wireless network. You should select from a range of transmission speeds, or you can select Auto to have the wireless router automatically use the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible connection speed between the router and a wireless client. The default setting is “Auto”.
65 Preamble Type The Preamble Type defines the length of the CRC (Cyclic Redundancy Check) block for communication between the router and wireless stations. Make sure to select the appropriate preamble type. Note that high network traffic areas should use the “Short Preamble”. CRC is a common technique for detecting data transmission errors. Broadcast SSID If this option is enabled, the router will automatically transmit the network name (SSID) into open air at regular interval. This feature is intended to allow clients to dynamically discover the router. If this option is disabled, the router will hide its SSID. When this is done, the clients cannot directly discover the router and MUST be configure with the SSID for accessing to the router. It is used to protect your network from being accessed easily. Relay Blocking When you enable this function, wireless clients will not be able to directly access other wireless clients. Protection This is also called CTS Protection. It is recommended to enable the protection mechanism. This mechanism can decrease the rate of data collision between 802.11b and 802.11g/802.11n wireless stations. When the protection mode is enabled, the throughput of the AP will be a little lower due to many of frame traffic should be transmitted. Aggregation This function is used to join multiple data packets for transmission as a single unit to increase network efficiency. Short GI The 802.11n draft specifies two guard intervals: 400ns (short) and 800ns (long). Support of the 400ns GI is optional for transmit and receive. Enable this function

With these security functions, you can prevent your wireless LAN from illegal access. Please make sure your wireless stations use the same security function.
67 Parameter Description Encryption You can choose “None” to disable the encryption or select “WEP”, “WPA(TKIP)”, “WPA2(AES)” or “WPA2 Mixed” mode for security. When “WEP” is enabled, please click “Set WEP Key” button to choose the default key and set the four sets of WEP keys. WEP –WEP is less level of security than WPA. WEP supports 64-bit and 128-bit key lengths to encrypt the wireless data. WPA(TKIP) – WPA uses Temporal Key Integrity Protocol (TKIP) for data encryption. TKIP utilized a stronger encryption method and incorporates Message Integrity Code (MIC) to provide protection against hackers. WPA2(AES) – WPA2, also known as 802.11i, uses Advanced Encryption Standard (AES) for data encryption. AES utilized a symmetric 128-bit block data
68 encryption. WPA Mixed – The router supports WPA (TKIP) and WPA2 (AES) for data encryption. The actual selection of the encryption methods will depend on the clients. Use 802.1x Authentication IEEE 802.1x is an authentication protocol. Every user must use a valid account to login to this wireless router before accessing the wireless LAN. The authentication is processed by a RADIUS server. Check this box to authenticates user by IEEE 802.1x. WEP-64Bits WEP is less level of security than WPA. WEP supports 64-bit and 128-bit key lengths to encrypt the wireless data. The longer key length will provide higher security. When “WEP-64Bits” is selected, you have to enter exactly 5 ASCII characters (“a-z” and “0-9”) or 10 hexadecimal digits ("0-9", "a-f") for each Key (1-4). WEP-128Bits When “WEP-128Bits” is selected, you have to enter exactly 13 ASCII characters (“a-z” and “0-9”) or 26 hexadecimal digits ("0-9", "a-f") for each Key (1-4). WPA Authentication Mode There are two types of authentication mode for WPA. Enterprise (RADIUS) – It uses an external RADIUS server to perform user authentication. To use RADIUS, enter the IP address of the RADIUS server, the RADIUS port (default is 1812) and the shared secret from the RADIUS server. Please refer to “Authentication RADIUS Server” setting below for RADIUS setting. Personal (Pre-Shared Key) – Pre-Shared Key authentication is based on a shared secret that is known only by the parties involved. To use WPA Pre-Shared Key, select key format and enter a password in the “Pre-
69 Shared Key Format” and “Pre-Shared Key” setting respectively. Pre-Shared Key Format You may select to select Passphrase (alphanumeric format) or Hexadecimal Digits (in the “A-F”, “a-f” and “0-9” range) to be the Pre-shared Key. For example: Passphrase: ”iamguest” Hexadecimal Digits: “12345abcde” Pre-Shared Key Please enter 8-63 characters as the “Pre-Shared Key”.

WPS Although home Wi-Fi networks have become more and more popular, users still have trouble with the initial set up of network. This obstacle forces users to use the open security and increases the risk of eavesdropping. Therefore, The Wi-Fi Protected Setup (WPS) is designed to ease set up of security-enabled Wi-Fi networks and subsequently network management. The largest difference between WPS-enabled devices and legacy devices is that users do not need the knowledge about SSID, channel and security settings, but they could still surf in a security-enabled Wi-Fi network. This device supports Push Button method and PIN method for WPS. The following sub-paragraphs will describe the function of each item. The webpage is as below.
72 Parameter Description Disable WPS Check to disable the Wi-Fi protected Setup. WPS Status When AP‟s settings are factory default (out of box), it is set to open security and un-configured state. “WPS Status” will display it as “UnConfigured”. If it already shows “Configured”, some registrars such as Vista WCN will not configure AP. Users will need to go to the “Backup/Restore” page and click “Reset” to reload factory default settings. Self-PIN Number “Self-PIN Number” is AP‟s PIN. Whenever users want to change AP‟s PIN, they could click “Regenerate PIN” and then click “ Apply Changes”. Moreover, if users want to make their own PIN, they could enter four-digit PIN without checksum and then click “ Apply Changes”. However, this would not be recommended since the registrar side needs to be supported with four-digit PIN. Regenerate PIN Click to regenerate the Self-PIN Number.

75 IP Pred: In QoS, a three-bit field in the ToS byte of the IP header (see RFC 791). Using IP Precedence, a network administrator can assign values from 0(the default) to 7 to classify and prioritize types of traffic. 802.1P: IEEE 802.1p is a 3 bit field within an Ethernet frame header when using tagged frames on an 802.1 network. It specifies a priority value of between 0 and 7 inclusive that can be used by Quality of Service (QoS) disciplines to differentiate traffic. Source IP The IP address of the traffic source. Netmask (Source) The source IP netmask. This field is required if the source IP has been entered. Port (Source) The source port of the selected protocol. You cannot configure this field without entering the protocol first. Destination IP The IP address of the traffic destination. Netmask (Destination) The destination IP netmask. This field is required if the destination IP has been entered. Port (Destination) The destination port of the selected protocol. You cannot configure this field without entering the protocol first. Protocol The selections are TCP, UDP, ICMP and the blank for none. This field is required if the source port or destination port has been entered. Physical Port The incoming ports. The selections include LAN ports,
76 wireless port, and the blank for not applicable. ClassQueue The priority level for the traffic that matches this classification rule. Please refer to 5.2.5.2 QOS Queue to create a ClassQueue. 802.1p_Mark Select this field to mark the 3-bit user-priority field in the 802.1p header of the packet that matches this classification rule. Note that this 802.1p marking is workable on a given PVC channel only if the VLAN tag is enabled in this PVC channel. IP.Pred_Mark Select this field to mark the IP precedence bits in the packet that match this classification rule. TOS_Mark The IP (Internet Protocol) uses the ToS (Type of Service) field to provide an indication of the quality of service desired. These parameters are to be used to guide the selection of the actual service parameters when transmitting an IP datagram through a particular network.0 IP QoS Rules This table lists the rules you have configured.

111 7. Glossary 10Base-T It is an Ethernet standard for Local Area Network (LAN). 10Base-T uses a twisted pair cable with maximum length of 100 meters. AAL ATM Adaptation Layer that defines the rules governing segmentation and reassembly of data into cells. Different AAL types are suited to different traffic classes. ADSL Asymmetric Digital Subscriber Line, as its name showing, is an asymmetrical data transmission technology with high traffic rate downstream and low traffic rate upstream. ADSL technology satisfies the bandwidth requirement of applications, which demand “asymmetric” traffic, such as web surfing, file download and Video-on-demand (VOD). ATM Asynchronous Transfer Mode is a layer 2 protocol supporting high-speed asynchronous data with advanced traffic management and quality of service features. bps Bits per second, a standard measurement of digital transmission speeds. Bridge A device that connects two or more physical networks and forwards packets between them. Bridges can usually be made to filter packets, that is, to forward only certain traffic. Related devices are: repeaters which simply forward electrical signals from one cable to the other and full-fledged routers which make routing decisions based on several criteria.
112 CPE Customer Premises Equipment, such as ADSL router, USB modem. Default Gateway (Router) Every non-router IP device needs to configure a default gateway‟s IP address. When the device sends out an IP packet, if the destination is not on the same network, the device has to send the packet to its default gateway, which will then send it out towards the destination. DHCP Dynamic Host Configuration Protocol, this protocol automatically gives every computer on your home network an IP address. DNS Server IP Address DNS stands for Domain Name System, which allows Internet servers to have a domain name (such as www. ADSLrouter.com) and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of Internet servers and their respective domain names and IP addresses, so that when a domain name is requested (as in typing " ADSLrouter.com" into your Internet browser), the user is sent to the proper IP address. The DNS server IP address used by the computers on your home network is the location of the DNS server your ISP has assigned to you. DSL Digital Line Subscriber (DSL) technology provides high-speed access over twisted copper pair for connection to the Internet, LAN interfaces, and to DSL services such as video-on-demand, distance learning, and video conferencing. Ethernet It is a standard for computer networks. Ethernet networks are connected by special cables and hubs or switches, and move data around at up to 10/100 million bits per second (Mbps).
113 FTP File Transfer Protocol. The Internet protocol (and program) used to transfer files between hosts. Idle Timeout Idle Timeout is designed so that after there is no traffic to the Internet for a pre-configured amount of time, the connection will automatically be disconnected. ISP Internet Service Provider is a business that provides connectivity to the Internet for individuals and other businesses or organizations. ISP Gateway Address The ISP Gateway Address is an IP address for the Internet router located at the ISP's office. LAN Local Area Network is a group of computers and devices connected together in a relatively small area (such as a house or an office). Your home network is considered a LAN. MAC Address MAC stands for Media Access Control. A MAC address is the hardware address of a device connected to a network. The MAC address is a unique identifier for a device with an Ethernet interface. It is comprised of two parts: 3 bytes of data that corresponds to the Manufacturer ID (unique for each manufacturer), plus 3 bytes that are often used as the product‟s serial number. MTU Maximum Transmission Unit NAT Network Address Translator is defined by RFC 1631. Enable a LAN network to use one set of IP address for internal traffic. A NAT box located where the LAN meets the Internet provides the necessary IP address translation. This helps
114 provide a sort of firewall and allow for a wider address range to be used internally without danger of conflict. Using the router‟s NAT capability, you can access the Internet from any computer on your home network without having to purchase more IP addresses from your ISP. Port Network Clients (LAN PC) uses port numbers to distinguish one network application/protocol over another. Below is a list of common applications and protocol/port numbers: Application Protocol Port Number Telnet TCP 23 FTP TCP 21 SMTP TCP 25 POP3 TCP 110 H.323 TCP 1720 SNMP UCP 161 SNMP Trap UDP 162 HTTP TCP 80 PPTP TCP 1723 PC Anywhere TCP 5631 PC Anywhere UDP 5632 PPP PPP is the Point-to-Point-Protocol. The successor to SLIP, PPP provides router-to-router and host-to-network connections over both synchronous and asynchronous circuits. PPPoA (RFC 2364) The Point-to-Point Protocol (PPP) provides a standard method for transporting multi-protocol data grams over point-to-point links. This document describes the use of ATM Adaptation Layer 5 (AAL5) for framing PPP encapsulated packets.
115 PPPoE (RFC 2516) This document describes how to build PPP sessions and encapsulate PPP packets over Ethernet. PPP over Ethernet (PPPoE) provides the ability to connect a network of hosts over a simple bridging access device to a remote Access Concentrator. Protocol A protocol is a set of rules for interaction agreed upon between multiple parties so that when they interface with each other based on such a protocol, the interpretation of their behavior is well defined and can be made objectively, without confusion or misunderstanding. PVC Permanent Virtual Circuit, connection-oriented permanent leased line circuit between end-stations on a network over a separate ATM circuit. RFC Request for Comments. The document series, begun in 1969, which describes the Internet suite of protocols and related experiments. Not all RFCs describe Internet standards, but all Internet standards are written up as RFCs. RFC 1483 Multi-protocol encapsulation over AAL-5. Two encapsulation methods for carrying network interconnect traffic over ATM AAL-5. The first method allows multiplexing of multiple protocols over a single ATM virtual circuit. The protocol of a carried PDU is identified by prefixing the PDU by an IEEE 802.2 Logical Link Control (LLC) header. This method is in the following called "LLC Encapsulation". The second method does higher-layer protocol multiplexing implicitly by ATM Virtual Circuits (VCs). It is in the following called "VC Based Multiplexing". Router A system responsible for making decisions about which of several paths network (or Internet) traffic will follow. To do this, it uses a routing protocol to gain information about the network and algorithms to choose the best route based on several criteria known as "routing metrics.
116 Subnet Mask A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of four numbers (e.g. 255.255.255.0) configured like an IP address. It is used to create IP address numbers used only within a particular network (as opposed to valid IP address numbers recognized by the Internet, which must be assigned by InterNIC). TCP/IP, UDP Transmission Control Protocol/Internet Protocol (TCP/IP) and Unreliable Datagram Protocol (UDP). TCP/IP is the standard protocol for data transmission over the Internet. Both TCP and UDP are transport layer protocol. TCP performs proper error detection and error recovery, and thus is reliable. UDP on the other hand is not reliable. They both run on top of the IP (Internet Protocol), a network layer protocol. TELNET It is the virtual terminal protocol in the Internet suite of protocols. Allows users of one host to log into a remote host and act as normal terminal users of that host. VCI Virtual Circuit Identifier is part of the ATM cell header. A VCI is a tag indicating the channel over which a cell will travel. The VCI of a cell can be changed as it moves between switches via Signaling. VPI Virtual Path Identifier is part of the ATM cell header. A VPI is a pipe for a number of Virtual Circuits. WAN Wide Area Network is a network that connects computers located in geographically separate areas (e.g. different buildings, cities, countries). The Internet is a wide area network.
117 Web-based management Graphical User Interface (GUI) Many devices support a graphical user interface that is based on the web browser. This means the user can use the familiar Netscape or Microsoft Internet Explorer to Control/configure or monitor the device being managed.
