The device allows you take advantages of both mobility and fast connection. All PCs whenever on wireless LAN or Ethernet LAN can share files, printers and other network resource. Moreover, all users can share single account of Internet access by having this device connect to a DSL/Cable modem. Ethernet / Fast Ethernet Ethernet is the most widely-used network access method, especially in a Local Area Nnetwork (LAN) and is defined by the IEEE as the 802.3 standard. Normally, Ethernet is a shared media LAN. All stations on the segment share the total bandwidth, which could be 10Mbps (Ethernet), 100Mbps (Fast Ethernet), or 1000Mbps (Gigabit Ethernet). With a switched Ethernet, each sender and receiver has the full bandwidth. Fast Ethernet is defined as IEEE 802.3u standard, a high-speed version of Ethernet with 100Mbps transmission rate. Wireless LAN Wireless Local Area Network systems (WLANs) transmit and receive data through the air by using radio frequency (RF). This offers some advantages like mobility, ease of installation, and scalability over traditional wired systems. Mobility: WLANs combine data connectivity with user mobility. This provides users with access to network anywhere in their organization. For example, users can roam from a conference room to their office without being disconnected from the LAN. This is impossible with wired networks. Ease of Installation: Eliminating the need to deploy network cable in walls and ceilings, Installing WLANs is easy for novice and expert users alike. Scalability: WLAN topologies are easy to change in various ways from peer-to-peer networks for a small group of users to full infrastructure networks for hundreds of users roaming over a broad area. Wireless LAN is suitable for difficult-to-wire and frequently changing environments. It’s also an ideal solution for mobile workers to access network resource and for setting a temporary LAN when necessary Wireless LANs can be set as “Aad-hoc” network and “Infrastructure” network. Unlike the “Aad-hoc network”, where users on the LAN send data directly to each other, the “Infrastructure” network includes an access point and users on the “Infrastructure” network send data to that dedicated access point. Advanced Wireless 11g Router uses -3- Broadband Wireless Router User Guide “Infrastructure” network as Wireless LANs. Each wireless LAN PC within the range of the access point can communicate with other wireless LAN PCs within the range. 1-2 Contents of the Advanced Wireless 11g Router Package After carefully unpacking the shipping carton, check the contents listed below. 1.

Whenerver you set up the web servers, mail servers, or sometimes ftp servers,you need a “Domain Name” to help Internet users reach your servers easily. Internet actually runs on IP Addresses which are numerical order, for example “66.37.215.53”. These IP Addresses identify the location of each device connected to the Internet. However, the human brain does not easily remember this numbering system, so a system that allocates a domain name such as “www.dyndns.org” provides an easier method. If you type “66.37.215.53” or “www.dyndns.org” in the web browser’s address bar, the browser will show the same web page. This is because both methods relate to the same web server. The “Domain Name Servers” used to manage the Internet will translate “www.dyndns.org” into the IP Address “66.37.215.53” in order to allow your browser to find the web server and display the correct web page in your browser. If your “WAN Connection Type”, as shown in One Page Setup section, is “Obtain IP - 28 - Broadband Wireless Router User Guide Address Automatically”, “PPPoE”, or “PPTP” with dynamic IP address assigned by ISP, it will cause an error when you set up the public computer servers in your LAN side PCs. Internet users may not be able to reach your servers because your WAN side IP address may change each time you initiate the connection to your ISP. The DDNS function will help to map your IP address to your domain name when your ISP assigns a new dynamic IP Address. Note that this DDNS function acts as the client appliance of DDNS service and is only able to be use in conjunction with the service provided by DynDNS.org. Before you begin using this function, you will need to apply to DynDNS.org to be able to use the service. Please visit www.dyndns.org for further information. DDNS Service check the “Enable” option if you wish to activate this function. Username After you have applied for the DDNS service from DynDNS.org, you will be issued with a Username. Enter this username in the “Username” field. Password DynDNS.org, will also issue you with a password. Enter the detail in the “Password” field. Host Name DynDNS.org, will provide you with a Host Name. Enter this name in the “Host Name” field. Your IP Address This will display the IP Address currently assigned by your ISP. Status This display the current status of the DDNS function. Click “Apply”to save any changes you have made. - 29 - Broadband Wireless Router User Guide 4-11 Wireless This setting page allows you to configure advanced wireless functions.

It is normally a text with ID number, but can include other information. DHCP DHCP, short for Dynamic Host Configuration Protocol, is a protocol for assigning dynamic IP Addresses to devices on a network. Dynamic Addressing means that a device can have a different IP Address each time it connects to the network. Domain Name A name that identifies one or more IP Addresses. For example, the domain name microsoft.com represents about a dozen IP Addresses. Domain names are used in URLs to identify particular Web pages. For example, in the URL http://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com. DoS DoS is the abbreviation for Denial of Service. This occurs when a computer or network is overwhelmed to the point that it can no longer function normally. For example, a hacker may use fake IP addresses to accumulate numerious connections to flood the server he wants to attack. DDNS DDNS is an acronym for Dynamic Domain Name Service. It helps map the domain name of a host which has a dynamic public IP address to the IP address that is allocated each time the ISP assigns a new IP address. DNS Short for Domain Name Server, DNS translates domain names into IP Addresses and help us recognize and remember domain names as they are alphabetic in form. The Internet actually runs on numbered IP Addresses. DNS servers translate domain names into their respective IP Addresses.

PPPoE Short for PPP over Ethernet, relying on two widely accepted standards, Ethernet and the Point-to-Point Protocol. It’s a communications protocol for transmitting information between devices from different manufacturers over an Ethernet. PPTP Short for Point to Point Tunneling Protocol, PPTP encapsulates the packet for transmission over the Internet. It is similar to creating a private “tunnel” over a large public network and has almost equal security to a private network without actually leasing a private line. Protocol An agreed format for transmitting, sending and receiving data between two devices. Roaming The ability for a wireless device moving from one access point’s range to another without losing the connection. - 44 - Broadband Wireless Router User Guide Router An Internet device that routes requests for information to other routers until the information’s location is found and the data can be transmitted back to the origin of the request. SPI SPI is an acronym for Stateful Packet Inspection. The SPI engine examines not just the headers of the packet, but also the packet contents, it can then determine more about the packet than just its source and destination information. Moreover, stateful inspection firewalls also close off ports until a connection to the specific port is requested. TCP/IP Short for Transmission Control Protocol and Internet Protocol, the suite of communications protocols that enable hosts on the Internet to connect and exchange streams of data. VPN VPN is an acronym for Virtual Private Network. Via access control and encryption, VPN brings the same security to data transmission through the Internet as if it being transmitted through a private network. It not only takes advantage of economies of scale but also ensures high level security while the packet is sent over the large public network. Wide Area Network (WAN) A system of LANs being connected by telephone lines and radio waves. Although someWANs may be privately owned, they are usually considered a means of public access. WEP An acronym for Wired Equivalent Privacy. It is an encryption mechanism used to protect your wireless data communications. WEP uses a combination of 64-bit/128-bit keys to encrypt data that is transmitted between all points in a wireless network to insure data security. It is described in the IEEE 802.11 standard. - 45 - FCC CAUTION 1. This Transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 2. Changes or modifications to this unit not expressly approved by the party responsible for compliance could void the user authority to operate the equipment.
