Page 65 Conﬁguring Security How Do I Know Which Security Mode to Use? In general, we recommend that on your Internal network you use the most robust security mode that is feasible in your environment. When conﬁguring security on the access point, you ﬁrst must choose the security mode, then in some modes an authentication algorithm, and whether to allow clients not using the speciﬁed security mode to associate.
Page 66 Conﬁguring Security Following is a list of the security modes available on the D-Link DWL-2210AP along with a description of the key management, authentication, and encryption algorithms used in each mode. We include some suggestions as to when one mode might be more appropriate than another.
Page 67 Static uses a ﬁxed key that is provided by the administrator. WEP keys are indexed in different slots (up to four on the D-Link DWL -2210AP). The client stations must have the same key indexed in the same slot to access data on the access point.

Page 70 Conﬁguring Security If there are older client stations on your network that do not support WPA, you can conﬁgure WPA with RADIUS (with Both, CCMP, or TKIP) and check the “Allow non-WPA IEEE 802.1x clients” checkbox to allow non-WPA clients. This way, you get the beneﬁt of IEEE 802.1x key management for non-WPA clients along with even better data protection of TKIP and CCMP (AES) key management and encryption algorithms for your WPA clients.
Page 71 Conﬁguring Security Recommendations WPA w/PSK not recommended for use with the D-Link DWL-2210AP when WPA with RADIUS is an option. We recommend that you use WPA with RADIUS mode instead, unless you have interoperability issues that prevent you from using this mode.
Page 72 Conﬁguring Security Navigating to Security Settings To set the security mode, navigate to the ﬁelds as described below. Conﬁguring Security Settings The following conﬁguration information explains how to conﬁgure security modes on the access point. Keep in mind that each wireless client that wants to exchange data with the access point must be conﬁgured with the same security mode and encryption key settings consistent with access point security.
Page 73: Guest Network
Security Mode Plaintext mode. Plaintext Plain Text means any data transferred to and from the D-Link DWL-2210AP is not encrypted. There are no further options for “Plaintext” mode. Plain text mode can be useful during initial network conﬁguration or for problem solving, but it is not recommended for regular use on the Internal network because it is not secure.
Page 74 Conﬁguring Security The absence of security on the Guest AP is designed to make it as easy as possible for guests to get a connection without having to program any security settings in their clients. For a minimum level of protection on a guest network, you can choose to suppress (prohibit) the broadcast of the SSID (network name) to discourage client stations from automatically discovering your access point.

Specify the authentication algorithm you want to use by choosing one of the following from the drop-down menu: •...
Page 77 Conﬁguring Security Rules to Remember for Static WEP All client stations must have the Wireless LAN (WLAN) security set to WEP and • all clients must have one of the WEP keys speciﬁed on the AP in order to decode AP-to-station data transmissions.

Page 82 Conﬁguring Security Field Cipher Suites Select the cipher you want to use from the drop-down menu: • TKIP • CCMP • Both Temporal Key Integrity Protocol (TKIP) is the default. TKIP provides a more secure encryption solution than WEP keys. The TKIP process more frequently changes the encryption key used and better ensures that the same key will not be reused to encrypt data (a weakness of WEP).

Page 93: Load Balancing
Load Balancing The D-Link DWL-2210AP allows you to balance the distribution of wireless client connections across multiple access points. Using load balancing, you can prevent scenarios where a single access point in your network shows performance degradation because it is handling a disproportionate share of the wireless trafﬁc.
Page 94 Load Balancing Specifying Limits for Utilization and Client Associations You can correct for imbalances in network AP utilization by enabling load balancing and setting limits on utilization rates and number of client associations allowed per access point. Load Balancing and QoS Load balancing also plays a part in contributing to Quality of Service (QoS) for Voice Over IP (VoIP) and other such time-sensitive applications competing for bandwidth and timely access to the air waves on a wireless network.

Page 96: Conﬁguring Queues For Quality Of Service
Quality of Service (QoS) provides you with the ability to specify parameters on multiple queues for increased throughput and better performance of differentiated wireless trafﬁc like Voice-over-IP (VoIP), video, and streaming media as well as traditional IP data over the D-Link DWL-2210AP. Description We recommend setting the maximum to between 30 and 50 client stations.
Page 97 Conﬁguring Queues for Qualty of Service (QoS) The following sections describe how to conﬁgure Quality of Service queues on the D-Link DWL-2210AP: • Understanding QoS • QoS and Load Balancing • 802.11e and WME Standards Support • QoS Queues and Parameters to Coordinate Trafﬁc Flow •...
Page 98 IP data which are less time-sensitive but often more data-intensive are expected to tolerate longer wait times. The D-Link DWL-2210AP implements QoS with a custom extension to the trafﬁc control mechanism in the Linux kernel. Our Linux-based queuing class is used to tag packets and establish multiple queues.
Page 99 • Downstream from network to access point QoS settings on the D-Link DWL-2210AP affect only the ﬁrst of these; downstream trafﬁc ﬂowing from the access point to client station. The other phases of the trafﬁc ﬂow are not under control of the QoS settings on the AP.
Page 100 Management and control frames wait a minimum amount of time for transmission; they wait a short interframe space (SIF). These wait times are built-in to 802.11 as infrastructure support and are not conﬁgurable. The D-Link DWL-2210AP supports the Distribution Coordination Function (DCF) as deﬁned by the 802.11e standard.
Page 101 Maximum Contention Window size is reached. Packet Bursting for Better Performance The D-Link DWL-2210AP includes 802.11e based packet bursting technology that increases data throughput and speed of transmission over the wireless network.

Page 105: Conﬁguring The Wireless Distribution System
Conﬁguring the Wireless Distribution System (WDS) The D-Link DWL-2210AP lets you connect multiple access points using a Wireless Distribution System (WDS).WDS allows access points to communicate with one another wirelessly in a standardized way. This capability is critical in providing a seamless experience for roaming clients and for managing multiple wireless networks.
Page 106 Conﬁguring the Wireless Distribution System (WDS) Using WDS to Bridge Distant Wired LANs In an ESS, a network of multiple access points, each access point serves part of an area which is too large for a single access point to cover. You can use WDS to bridge distant Ethernets to create a single LAN.
Page 107 Another use for WDS bridging, the creation of backup links, is not supported in this release of the D-Link DWL-2210AP. The topic is included here to emphasize that you should not try to use WDS in this way; backup links will result in unwanted, endless loops of data trafﬁc.
Page 108 Conﬁguring the Wireless Distribution System (WDS) Navigating to WDS Settings To specify the details of trafﬁc exchange from this access point to others, navigate to Advanced > WDS tab, and update the ﬁelds as described below. The following ﬁgure shows the WDS settings page for the two-radio AP. The Administration Web page for the one-radio AP will look slightly different.
Page 109 WDS bridges. Spanning Tree Protocol (STP), which manages path redundancy and prevent unwanted loops, is not enabled for this release. Keep these rules in mind when working with WDS on this release of the D-Link DWL-2210AP: • Any two access points can be connected by only a single path; either a WDS bridge (wireless) or an Ethernet connection (wired), but not both.
Page 110 “handed-off” and from which data will be received. The D-Link DWL-2210AP provides the capability of setting up and internal networks on the same access point. (See “Setting up Guest Access” in this manual.) The guest network typically provides internet access but isolates guest clients from more sensitive areas of your internal network.
Page 111 Conﬁguring the Wireless Distribution System (WDS) Field Key Type Characters Required WEP Key Example of Conﬁguring a WDS Link When using WDS, be sure to conﬁgure WDS settings on both access points on the WDS link. For example, to create a WDS link between a pair of access points “MyAP1” and “MyAP2” do the following: Description If WEP is enabled, specify the WEP key type:...

Page 166: Glossary
Glossary IEEE 802 (IEEE Std. 802-2001) is a family of standards for peer-to-peer communication over a LAN. These technologies use a shared-medium, with information broadcast for all stations to receive. The basic communications capabilities provided are packet-based. The basic unit of transmission is a sequence of data octets (8-bits), which can be of any length within a range that is dependent on the type of LAN.
Page 167: Access Point
Glossary 802.11b IEEE 802.11b (IEEE Std. 802.11b-1999) is an enhancement of the initial 5.5 Mbps and 11 Mbps data rates. It uses direct sequence spread spectrum (DSSS) or frequency hopping spread spectrum (FHSS) in the 2.4 GHz ISM band as well as complementary code keying (CCK) to provide the higher data rates.
Page 168 Glossary When one access point is connected to a wired network and supports a set of wireless stations, it is referred to as a basic service set (BSS). An extended service set (ESS) is created by combining two or more BSSs. Ad hoc Mode Ad hoc mode is a Wireless Networking Framework...
Page 169 Glossary Broadcast A Broadcast sends the same message at the same time to everyone. In wireless networks, broadcast usually refers to an interaction in which the access point sends data trafﬁc in the form IEEE 802.1x Frames to all client stations on the network. Some wireless security modes distinguish between how unicast, multicast, and broadcast frames are encrypted or whether they are encrypted.
Page 170 Glossary CSMA/CA Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) is a low-level network arbitration/contention protocol. A station listens to the media and attempts to transmit a packet when the channel is quiet. When it detects that the channel is idle, the station transmits the packet.
Page 171: Dynamic Ip Address
Glossary The Document Object Model (DOM) is an interface that allows programs and scripts to dynamically access and update the content, structure, and style of documents. The DOM allows you to model the objects in an HTML or XML document (text, links, images, tables), deﬁning the attributes of each object and how they can be manipulated.
Page 172 Glossary Legacy IEEE 802.11b devices cannot detect the ERP-OFDM signals used by IEEE 802.11g stations, and this can result in collisions between data frames from IEEE 802.11b and IEEE 802.11g stations. If there is a mix of 802.11b and 802.11g nodes on the same channel, the IEEE 802.11g stations detect this via an ERP ﬂag on the access point and enable request to send (RTS) and clear to send (CTS) protection before sending data.

Wireless Ethernet (802.11) is another very popular LAN technology (also see WLAN). LDAP The Lightweight Directory Access Protocol (LDAP) is a protocol for accessing online directory services.
Page 176 Glossary Multicast A Multicast sends the same message to a select group of recipients. Sending an e-mail message to a mailing list is an example of multicasting. In wireless networks, multicast usually refers to an interaction in which the access point sends data trafﬁc in the form of speciﬁed set of client stations Some wireless security modes distinguish between how unicast, multicast, and broadcast frames are encrypted or whether they are encrypted.

Page 178 Glossary The Point-to-Point Protocol is a standard for transmitting network layer datagrams over serial point-to-point links. PPP is designed to operate both over asynchronous connections and bit-oriented synchronous systems. PPPoE Point-to-Point Protocol over Ethernet (PPPoE) is a speciﬁcation for connecting the users on to the Internet through a common broadband medium, such as a single DSL or cable modem line.
Page 179 Glossary Router A router is a network device which forwards packets between networks. It is connected to at least two networks, commonly between two local area networks (LANs) or between a a wide-area network (WAN), for example, the Internet. Routers are located at gateways—places where two or more networks connect.
Page 180 Glossary SNMP consists of managed devices and their agents, and a management system. The agents store data about their devices in Management Information Bases (MIBs) and return this data to the SNMP management system when requested.
