Then press Enter on your keyboard, you will see the Enter Network Password dialog box appear like the picture below shows.

The default User Name and Password is nil. Leave User Name and Password field blank and then click OK.

Note: You may set a new password by clicking the Admin tab after you enter the Web Configuration page .

4.1 Web Configuration Interface

Under the main web interface page you will see the following configuration menu pages:

Info, Configuration, Encryption, Advanced, Admin, and Help. Check the sections below for detail information on the contents of each menu interface.

4.2 Info Page

Access Point Information

This section provides the basic access point information in which this unit is associated with in bridge mode.

Bridge Information

This section provides the basic bridge setting information.

4.3 Configuration Page

Wireless Network Type

Infrastructure: An 802.11 networking framework in which devices communicate with each other by first going through an Access Point (AP).

Ad-hoc: An 802.11 networking framework in which devices or stations communicate directly with each other, without the use of an access point (AP). Use this mode if there is no wireless infrastructure or where services are not required.

Wireless Network Name (SSID)

Network Name is also known as SSID, which stands for Service Set Identifier. Any client in Infrastructure mode has to indicate the SSID of the intended Access Point to start accessing the service from behind such as internet access. Type in the name of the Wireless Access Point to connect this Bridge to an AP.

Channel

Channels are important to understand because they affect the overall capacity of your Wireless LAN. A channel represents a narrow band of radio frequency. A radio frequency modulates within a band of frequencies; as a result, there is a limited amount of bandwidth within any given range to carry data. It is important that the frequencies do not overlap or else the throughput would be significantly lowered as the network sorts and reassembles the data packets sent over the air.

These are the only 3 channels out of the 11 available that do not overlap with one another. To avoid interference within the network with multiple APs, set each AP to use one of the 3 channels (e.g. Channel 1) and then the other AP to be one of the other 2 channels (i.e. Channel 6 or Channel

11) within the range of the wireless radio. This simple method will reduce

interference and improve network reliability.

802.11b/g Wireless Channel Frequency Range: 2.4 GHz – 2.497 GHz

Non-overlapping Channel Frequency Ranges Channel 1 = 2.401 GHz – 2.423 GHz Channel 6 = 2.426 GHz – 2.448 GHz Channel 11 = 2.451 GHz – 2.473 GHz

Americas: Wireless Channels 1-11 Asia: Wireless Channels 1 – 14

Europe: Wireless Channels 1-13

Transmission rate (Mbits/s)

This option indicates the transmission rate of the bridge. Specify the rate according to the speed of your wireless network from the list. Most of the time the default setting Best (automatic) should be selected for best performance. You may want to adjust the setting manually If your link quality and signal strength is usually low or high to get the best performance.

Wireless Mode

Wireless mode allows the user to select whether this Bridge will connect to an 802.11g only network, an 802.11b only network, or both types of networks. If you only have b or g wireless devices on the network selecting

802.11b or 802.11g only network will provide better performance then in

mixed mode.

4.4 Encryption Page

WPA Configuration

Short for Wi-Fi Protected Access, a Wi-Fi standard that was designed to improve upon the security features of WEP. WPA has the following improvements over the WEP.

• Improved data encryption through the temporal key integrity protocol (TKIP). TKIP scrambles the keys using a hashing algorithm and, by adding an integrity-checking feature, ensures that the keys haven’t been tampered with.

• User authentication, which is generally missing in WEP, through the extensible authentication protocol (EAP). WEP regulates access to a wireless network based on a computer’s hardware-specific MAC address, which is relatively simple to be sniffed out and stolen. EAP is built on a more secure public-key encryption system to ensure that only authorized network users can access the network.

WPA enabled

Hex Digits = 0-9 and A-F

Deny unencrypted data

Force the peer connection(s) to this bridge to use encryption to farther increase security.

Authentication

• Open - Open system authentication involves a two-step authentication transaction sequence. The first step in the sequence is the identity assertion and request for authentication. The second step in the sequence is the authentication result. If it is “successful”, The station shall be mutually authenticated.

Open system authentication does not provide authentication. It provides identification using the wireless adapter's MAC address. Open system authentication is used when no authentication is required. It is the default authentication algorithm.

Open system authentication uses the following process:

1. The authentication-initiating wireless client sends an IEEE 802.11 authentication management frame that contains its identity.

2. The receiving wireless AP checks the initiating station's identity and sends back an authentication verification frame.

With some wireless APs, you can configure the MAC addresses of allowed wireless clients. However, configuring the MAC address does not provide sufficient security because the MAC address of a wireless client can be spoofed.

• Shared Key - Shared key authentication supports authentication of stations as either a member of those who know a shared secret key or a member of those who do not.

Shared key authentication is not secure and is not recommended for use. It verifies that an authentication-initiating station has knowledge of a shared secret. This is similar to preshared key authentication for Internet Protocol security (IPSec). The 802.11 standard currently assumes that the shared secret is delivered to the participating wireless clients by means of a more secure channel that is independent of IEEE 802.11. In practice, a user manually types this secret for the wireless AP and the wireless client.

Shared key authentication uses the following process:

1. The authentication-initiating wireless client sends a frame consisting of an identity assertion and a request for authentication.

2. The authenticating wireless node responds to the authenticationinitiating wireless node with challenge text.

3. The authentication-initiating wireless node replies to the authenticating wireless node with the challenge text that is encrypted using WEP and an encryption key that is derived from the shared key authentication secret.

4. The authentication result is positive if the authenticating wireless node determines that the decrypted challenge text matches the challenge text originally sent in the second frame. The authenticating wireless node sends the authentication result.

Because the shared key authentication secret must be manually distributed and typed, this method of authentication does not scale appropriately in large infrastructure network mode, such as corporate campuses.

Cloning

Cloning Mode

• Ethernet Client

If set to "Ethernet Client", the MAC Address from the first Ethernet client that transmits data through the Bridge will be used. Which means the client MAC address will become the alias address to the Bridge.

• WLAN Card

If set to "WLAN Card", the MAC Address of the WLAN Card will be used. When multiple Ethernet devices are connected to the Bridge, the MAC Address of the Bridge will not change.

Advanced Wireless

Fragmentation threshold

Fragmentation Threshold is the maximum length of the frame, beyond which payload must be broken up (fragmented) into two or more frames. Collisions occur more often for long frames because sending them occupies the channel for a longer period of time, increasing the chance that another station will transmit and cause collision. Reducing Fragmentation Threshold results in shorter frames that "busy" the channel for shorter periods, reducing packet error rate and resulting retransmissions. However, shorter frames also increase overhead, degrading maximum possible throughput, so adjusting this parameter means striking a good balance between error rate and throughput.

RTS threshold

RTS Threshold is the frame size above which an RTS/CTS handshake will be performed before attempting to transmit. RTS/CTS asks for permission to transmit to reduce collisions, but adds considerable overhead. Disabling RTS/CTS can reduce overhead and latency in WLANs where all stations are close together, but can increase collisions and degrade performance in WLANs where stations are far apart and unable to sense each other to avoid collisions (aka Hidden Nodes). If you are experiencing excessive collisions, you can try turning RTS/CTS on or (if already on) reduce RTS/CTS Threshold on the affected stations.

Maximum burst time

Maximum burst time is a feature based on the PRISM Nitro; a new WLAN software solution that more than triples 802.11g throughput in a mixedmode environment and offers up to 50 percent greater throughput performance in 802.11g-only networks. PRISM Nitro is fully IEEE 802.11 compliant and uses prioritization algorithms and enhanced protection mechanisms to significantly increase wireless networking performance.

The recommended value for the maximum burst time for 11b or the mixed 11b/g environment is 650. For the 11g only mode use the value 1400.

Beacon period

In wireless networking, a beacon is a packet sent by a connected device to inform other devices of its presence and readiness. When a wirelessly networked device sends a beacon, it includes with it a beacon interval, which specifies the period of time before it will send the beacon again. The interval tells receiving devices on the network how long they can wait in low-power mode before waking up to handle the beacon. Network managers can adjust the beacon interval, usually measured in milliseconds (ms) or its equivalent, kilo microseconds (Kmsec).

DTIM interval

Delivery Traffic Indication Message. A DTIM is a signal sent as part of a beacon by an access point to a client device in sleep mode, alerting the device to a packet awaiting delivery. A DTIM interval, also known as a Data Beacon Rate, is the frequency at which an access point's beacon will

include a DTIM. This frequency is usually measured in milliseconds (ms) or its equivalent, kilo microseconds (Kmsec).

Maximum burst time

The recommended value for the maximum burst time for 11b or the mixed 11b/g environment is 650. For the 11g only mode use the value 1400.

Appendix F: Glossary

802.1x - The standard for wireless LAN authentication used between an AP

and a client. 802.1x with EAP will initiate key handling.

Ad-Hoc Network - The wireless network based on a peer-to-peer communications session. Also referred to as AdHoc.

Access Point - Access points are stations in a wireless LAN that are connected to an Ethernet hub or server. Users can roam within the range of access points and their wireless device connections are passed from one access point to the next.

Authentication - Authentication refers to the verification of a transmitted message's integrity.

Beacon - In wireless networking, a beacon is a packet sent by a connected device to inform other devices of its presence and readiness.

Beacon interval - When a wirelessly networked device sends a beacon, it includes with it a beacon interval, which specifies the period of time before it will send the beacon again. The interval tells receiving devices on the network how long they can wait in low-power mode before waking up to handle the beacon. Network managers can adjust the beacon interval, usually measured in milliseconds (ms) or its equivalent, kilo microseconds (Kmsec).

BSS - Basic Service Set. When a WLAN is operating in infrastructure mode, each access point and its connected devices are called the Basic Service Set.

BSSID - The unique identifier for an access point in a BSS network. See SSID for more details.

DHCP - DHCP (Dynamic Host Configuration Protocol) software automatically assigns IP addresses to client stations logging onto a TCP/IP network, which eliminates the need to manually assign permanent IP addresses.

DSSS (Direct Sequence Spread Spectrum) - Method of spreading a wireless signal into wide frequency bandwidth.

Dynamic IP Address - An IP address that is automatically assigned to a client station in a TCP/IP network, typically by a DHCP server. DNS (Domain Name System): System used to map readable machine names into IP addresses

DTIM - DTIM (Delivery Traffic Indication Message) provides client stations with information on the next opportunity to monitor for broadcast or multicast messages.

DTIM interval - A DTIM interval, also known as a Data Beacon Rate, is the frequency at which an access point's beacon will include a DTIM. This frequency is usually measured in milliseconds (ms) or its equivalent, kilo microseconds (Kmsec).

ESS - Extended Service Set. ESS is the collective term for two or more BSSs that use the same switch in a LAN.

ESSID - Extended Service Set Identifier. An ESSID is the unique identifier for an ESS. See SSID for more details.

Filter - Filters are schemes, which only allow specified data to be transmitted. For example, the router can filter specific IP addresses so that users cannot connect to those addresses. Firmware: Programming inserted into programmable read-only memory, thus becoming a permanent part of a computing device.

Fragmentation - Refers to the breaking up of data packets during transmission.

Gateway - Gateways are computers that convert protocols enabling different networks, applications, and operating systems to exchange information.

IBSS - Independent Basic Service Set. See ad-hoc network

Infrastructure Mode - When a wireless network functions in infrastructure

mode, every user communicates with the network and other users through an access point; this is the typical way corporate WLANs work. An alternative is ad-hoc mode, but users would have to switch to infrastructure mode to access a network's printers and servers.

ISP - An ISP is an organization providing Internet access service via modems, ISDN (Integrated Services Digital Network), and private lines.

LAN(Local Area Network): A group of computers and peripheral devices connected to share resources. MAC (Medium Access Control) Address: A unique number that distinguishes network cards.

MTU - MTU (Maximum Transmission/Transfer Unit) is the largest packet size that can be sent over a network. Messages larger than the MTU are divided into smaller packets.

NAT - NAT (Network Address Translation - also known as IP masquerading) enables an organization to present itself to the Internet with one address. NAT converts the address of each LAN node into one IP address for the Internet (and vice versa). NAT also provides a certain amount of security by acting as a firewall by keeping individual IP addresses hidden from the WAN.

Preamble - Preamble refers to the length of a CRC (Cyclic Redundancy Check) block that monitors’ communications between roaming wireless enabled devices and access points.

Protocol - A standard way of exchanging information between computers. RADIUS (Remote Authentication Dial In User Service): A server that issues authentication key to clients. RAM (Random Access Memory): Non-permanent memory.

RIP - RIP (Routing Information Protocol) is a routing protocol that is integrated in the TCP/IP protocol. RIP finds a route that is based on the smallest number of hops between the source of a packet and its destination.

Router - Device that can connect individual LANs and remote sites to a server. Roaming - The ability to use a wireless device while moving from one access point to another without losing the connection.

RTS - RTS (Request To Send) is a signal sent from the transmitting station to the receiving station requesting permission to transmit data.

Server - Servers are typically powerful and fast machines that store programs and data. The programs and data are shared by client machines (workstations) on the network.

Static IP Address - A permanent IP address is assigned to a node in a

TCP/IP network. Also known as global IP.

Subnet Mask - Subnet Masks (SUBNET work masks) are used by IP protocol to direct messages into a specified network segment (i.e., subnet). A subnet mask is stored in the client machine, server or router and is compared with an incoming IP ad-dress to determine whether to accept or reject the packet.

SSID - SSID (Service Set Identifier) is a security measure used in WLANs. The SSID is a unique identifier attached to packets sent over WLANs. This identifier emulates a password when a wireless device attempts communication on the WLAN. Because an SSID distinguishes WLANS from each other, access points and wireless devices trying to connect to a WLAN must use the same SSID.

TCP/IP - TCP/IP (Transmission Control Protocol/Internet Protocol) is the main Internet communications protocol. The TCP part ensures that data is completely sent and received at the other end. Another part of the TCP/IP protocol set is UDP, which is used to send data when accuracy and guaranteed packet delivery are not as important (for example, in real-time video and audio transmission).

TFTP (Trivial File Transfer Protocol) - Simple form of FTP (File Transfer Protocol), which Uses UDP (User Datagram Protocol), rather than TCP/IP for data transport and provides no security features. TKIP (Temporal Key Integrity Protocol): An encryption method replacing WEP.TKIP uses random IV and frequent key exchanges.

UDP (User Datagram Protocol) - A communication method (protocol) that offers a limited amount of service when messages are exchanged between computers in a network. UDP is used as an alternative to TCP/IP.

Uplink: Link to the next level up in a communication hierarchy.

UTP (Unshielded Twisted Pair) cable - Two or more unshielded wires

twisted together to form a cable.

Virtual Servers - Virtual servers are client servers (such as Web servers) that share resources with other virtual servers (i.e., it is not a dedicated server).

WEP (Wired Equivalent Privacy) - An encryption method based on 64 or

128bit algorithm.

WLAN - WLANs (Wireless LANs) are local area networks that use wireless communications for transmitting data. Transmissions are usually in the 2.4 GHz band. WLAN devices do not need to be lined up for communications like infrared devices. WLAN devices use access points, which are connected to the wired LAN and provide connectivity to the LAN. The radio frequency of WLAN devices is strong enough to be transmitted through non-metal walls and objects, and can cover an area up to a thousand feet. Laptops and notebooks use wireless LAN PCMCIA cards while PCs use plug-in cards to access the WLAN.
