Chapter 10: Configuring Security Understanding Security Issues On Wireless Networks The following sections describe how to configure Security settings on the 9160 G2 Wireless Gateway. 10.1 Understanding Security Issues On Wireless Networks Wireless mediums are inherently less secure than wired mediums. For example, an Ethernet NIC transmits its packets over a physical medium such as coaxial cable or twisted pair.
Chapter 10: Configuring Security Comparison Of Security Modes For Key Management, Authentication And Encryption Algorithms convenience trade-off for other scenarios where the priority is making it as easy as possible for clients to connect. (See “Does Prohibiting The Broadcast SSID Enhance Security?” on page 99) Following is a brief discussion of what factors make one mode more secure than another, a description of each mode offered, and when to use each mode. 10.1.
Chapter 10: Configuring Security Comparison Of Security Modes For Key Management, Authentication And Encryption Algorithms See Also For information on how to configure unencrypted security mode, see “None (Plain-text)” on page 102. 10.1.2.2 When To Use Static WEP Static Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks.
Chapter 10: Configuring Security Comparison Of Security Modes For Key Management, Authentication And Encryption Algorithms Table 10.2 IEEE 801.1x Security Mode Key Management Encryption Algorithm User Authentication IEEE 802.1x provides dynamically-generated keys that are periodically refreshed. An RC4 stream cipher is used to encrypt the frame body and cyclic redundancy checking (CRC) of each 802.11 frame. IEEE 802.
Chapter 10: Configuring Security Comparison Of Security Modes For Key Management, Authentication And Encryption Algorithms This security mode is backwards-compatible for wireless clients that support only the original WPA. Table 10.3 WPA Personal Security Mode Key Management Encryption Algorithms User Authentication WPA Personal provides dynamically-generated keys that are periodically refreshed. • Temporal Key Integrity Protocol (TKIP).
Chapter 10: Configuring Security Comparison Of Security Modes For Key Management, Authentication And Encryption Algorithms Table 10.4 WPA Enterprise Security Mode Key Management Encryption Algorithms User Authentication WPA Enterprise mode provides dynamically-generated keys that are periodically refreshed. • Temporal Key Integrity Protocol (TKIP). Remote Authentication Dial-In User Service (RADIUS) • Counter mode/CBC-MAC Protocol (CCMP) Advanced Encryption Standard (AES).
Chapter 10: Configuring Security Does Prohibiting The Broadcast SSID Enhance Security? Client stations that support CCMP can use it for their Unicast frames. If you encounter AP-to-station interoperability problems with the “Both” encryption algorithm setting, then you will need to select TKIP instead. (See next option.) 3. The third best choice is WPA Enterprise with the encryption algorithm set to TKIP. Some clients have interoperability issues with CCMP and TKIP enabled at same time.
Chapter 10: Configuring Security Configuring Security Settings 10.2 Configuring Security Settings To set the security mode, navigate to the Security tab, and update the fields as described below. Figure 10.1 Security Settings Page The following configuration information explains how to configure security modes on the access point.
Chapter 10: Configuring Security Broadcast SSID, Station Isolation, And Security Mode Table 10.5 Security Settings Field Description Broadcast SSID To enable the Broadcast SSID, select the checkbox directly beside it. By default, the access point broadcasts (allows) the Service Set Identifier (SSID) in its beacon frames. You can suppress (prohibit) this broadcast to discourage stations from automatically discovering your access point.
Chapter 10: Configuring Security Security Modes 10.2.2 Security Modes 10.2.2.1 None (Plain-text) None (or plain-text security) means any data transferred to and from the 9160 G2 Wireless Gateway is not encrypted. If you select None (Plain-text) as your Security Mode, no further options are configurable on the AP. This security 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.
Chapter 10: Configuring Security Security Modes 10.2.2.2 Static WEP Wired Equivalent Privacy (WEP) is a data encryption protocol for 802.11 wireless networks. All wireless stations and access points on the network are configured with a static 64-bit (40-bit secret key + 24-bit initialization vector (IV)) or 128-bit (104-bit secret key + 24-bit IV) Shared Key for data encryption. You cannot mix 64-bit and 128-bit WEP keys between the access point and its client stations.
Chapter 10: Configuring Security Security Modes Table 10.6 Static WEP Security Settings Field Description Transfer Key Index Select a key index from the drop-down menu. Key indexes 1 through 4 are available. The default is 1. The Transfer Key Index indicates which WEP key the access point will use to encrypt the data it transmits.
Chapter 10: Configuring Security Security Modes Table 10.6 Static WEP Security Settings Field Description Authentication Algorithm The authentication algorithm defines the method used to determine whether a client station is allowed to associate with an access point when static WEP is the security mode. Specify the authentication algorithm you want to use by choosing one of the following from the drop-down menu: • Open System. • Shared Key. • Both.
Chapter 10: Configuring Security Security Modes • On some wireless client software (like Funk Odyssey), you can configure multiple WEP keys and define a client station “transfer key index”, and then set the stations to encrypt the data they transmit using different keys. This ensures that neighboring APs cannot decode each other’s transmissions. Example Of Using Static WEP For a simple example, suppose you configure three WEP keys on the access point.
Chapter 10: Configuring Security Security Modes Figure 10.3 Providing A Wireless Client With A WEP Key If you have a second client station, that station also needs to have one of the WEP keys defined on the AP. You could give it the same WEP key you gave to the first station. Or for a more secure solution, you could give the second station a different WEP key (key 2, for example) so that the two stations cannot decrypt each other’s transmissions.

The Personal version of WPA employs a pre-shared key (instead of using IEEE 802.1x and EAP as is used in the Enterprise WPA security mode). The PSK is used for an initial check of credentials only.
Chapter 10: Configuring Security Security Modes Table 10.8 WPA Personal Security Settings Field Description WPA Versions Select the types of client stations you want to support: • WPA • WPA2 • Both WPA. If all client stations on the network support the original WPA but none support the newer WPA2, then select WPA. WPA2. If all client stations on the network support WPA2, we suggest using WPA2 which provides the best security per the IEEE 802.11i standard. Both.
Chapter 10: Configuring Security Security Modes Table 10.8 WPA Personal Security Settings Field Description Cipher Suites Select the cipher suite you want to use: • TKIP • CCMP (AES) • 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 re-used to encrypt data (a weakness of WEP).
Chapter 10: Configuring Security Security Modes This security mode is backwards-compatible with wireless clients that support the original WPA. When configuring WPA Enterprise mode, you have a choice of whether to use the built-in RADIUS server or an external RADIUS server that you provide. The 9160 G2 Wireless Gateway built-in RADIUS server supports Protected EAP (PEAP) and MSCHAP V2.

You need to convert the reported time to your local time.
Chapter 11: Maintenance And Monitoring Depth If you set the Severity level to 7, all messages with a severity level between 7 and 0 will appear in the Event log. Alternatively, if you want to filter messages, you can set the Severity level to 4. In this instance, all messages with a severity level between 4 and 0 will appear in the Event log. Therefore, less severe messages and notices will be ignored. Table 11.
Chapter 11: Maintenance And Monitoring Log Relay Host For Kernel Messages You cannot view Kernel Log messages directly from the Administration Web UI for an access point. You must first set up a remote server running a syslog process and acting as a syslog “log relay host” on your network. Then, you can configure the 9160 G2 Wireless Gateway to send its syslog messages to the remote server. Using a remote server to collect access point syslog messages affords you several benefits.
Chapter 11: Maintenance And Monitoring Log Relay Host For Kernel Messages Note: The syslog process will default to use port 514. We recommend keeping this default port. However; If you choose to reconfigure the log port, make sure that the port number you assign to syslog is not being used by another process. 11.2.4.
Chapter 11: Maintenance And Monitoring Events Log 11.2.5 Events Log The Events Log shows system events on the access point such as stations associating, being authenticated, and other occurrences. The real-time Events Log is always shown on the Status, Events Administration Web UI page for the access point you are monitoring. 11.

Chapter 19: Quality Of Service (QoS) Understanding QoS 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), other types of audio, video, and streaming media, as well as traditional IP data over the 9160 G2 Wireless Gateway. The following sections describe how to configure Quality of Service queues on the 9160 G2 Wireless Gateway. 19.
Chapter 19: Quality Of Service (QoS) QoS Queues And Parameters To Coordinate Traffic Flow The 9160 G2 Wireless Gateway provides QoS based on the Wireless Multimedia (WMM) specification and Wireless Multimedia (WMM) standards, which are implementations of a subset of 802.11e features. Both access points and wireless clients (laptops, consumer electronics products) can be WMM-enabled. 19.1.
Chapter 19: Quality Of Service (QoS) QoS Queues And Parameters To Coordinate Traffic Flow The access point examines the ToS field in the headers of all packets that pass through the AP. Based on the value in a packet’s ToS field, the AP prioritizes the packet for transmission by assigning it to one of the queues. This process occurs automatically, regardless of whether you deliberately configure QoS or not. A different type of data is associated with each queue.
Chapter 19: Quality Of Service (QoS) QoS Queues And Parameters To Coordinate Traffic Flow from the AP to the client station (AP EDCA parameters). The other phases of the traffic flow (to and from the network) are not under control of the QoS settings on the AP. 19.1.3.2 EDCF Control Of Data Frames And Arbitration Interframe Spaces Data is transmitted over 802.11 wireless networks in frames.
Chapter 19: Quality Of Service (QoS) QoS Queues And Parameters To Coordinate Traffic Flow 19.1.3.3 Random Backoff And Minimum/Maximum Contention Windows If an access point detects that the medium is in use (busy), it uses the DCF random backoff timer to determine the amount of time to wait before attempting to access a given channel again. Each access point waits some random period of time between retries.
Chapter 19: Quality Of Service (QoS) 802.1p And DSCP Tags information. The effect of this is to increase network speed and data throughput. The size of packet bursts allowed (maximum burst length) is a configurable parameter. 19.1.3.5 Transmission Opportunity (TXOP) Interval For Client Stations The Transmission Opportunity (TXOP) is an interval of time when a Wi-Fi Multimedia (WMM) client station has the right to initiate transmissions onto the wireless medium (WM). 19.1.4 802.1p And DSCP Tags IEEE 802.

Chapter 19: Quality Of Service (QoS) Configuring QoS Queues Figure 19.3 Quality Of Service (QoS) Settings Configuring Quality of Service (QoS) on the 9160 G2 Wireless Gateway consists of setting parameters on existing queues for different types of wireless traffic, and effectively specifying minimum and maximum wait times (via Contention Windows) for transmission. The settings described here apply to data transmission behaviour on the access point only, not to that of the client stations.
Chapter 19: Quality Of Service (QoS) Configuring AP EDCA Parameters is the case on both one-radio and two-radio APs. QoS on the access point leverages existing information in the IP packet header related to Type of Service (ToS). The access point examines the ToS field in the headers of all packets that pass through the AP. Based on the value in a packet’s ToS field, the AP prioritizes the packet for transmission by assigning it to one of the queues. A different type of data is associated with each queue.
Chapter 19: Quality Of Service (QoS) Configuring AP EDCA Parameters Table 19.3 AP EDCA Parameters Field Description AIFS (Inter-Frame Space) The Arbitration Inter-Frame Spacing (AIFS) specifies a wait time (in milliseconds) for data frames. Valid values for AIFS are 1 through 255. For more information, see DCF Control of Data Frames and Interframe Spaces. For more information, see “EDCF Control Of Data Frames And Arbitration Interframe Spaces” on page 190.
Chapter 19: Quality Of Service (QoS) Enabling/Disabling Wi-Fi Multimedia Table 19.3 AP EDCA Parameters Field Description Max. Burst Length AP EDCA Parameter Only (The Max. Burst Length applies only to traffic flowing from the access point to the client station.) This value specifies (in milliseconds) the Maximum Burst Length allowed for packet bursts on the wireless network. A packet burst is a collection of multiple frames transmitted without header information.
Chapter 19: Quality Of Service (QoS) Configuring Station EDCA Parameters Table 19.4 Station EDCA Parameters Field Description Queue Queues are defined for different types of data transmitted from station-to-AP: Data 0 (Voice) Highest priority queue, minimum delay. Time-sensitive data such as VoIP and streaming media are automatically sent to this queue. Data 1(Video) Highest priority queue, minimum delay. Time-sensitive video data is automatically sent to this queue.
Chapter 19: Quality Of Service (QoS) Updating Settings Table 19.4 Station EDCA Parameters Field Description cwMax (Maximum Contention Window) The value specified here in the Maximum Contention Window is the upper limit (in milliseconds) for the doubling of the random backoff value. This doubling continues until either the data frame is sent or the Maximum Contention Window size is reached.

Static WEP does not provide effective data protection to the level of other security modes available for service to client stations.
Chapter 20: Wireless Distribution System Configuring WDS Settings Figure 20.3 Wireless Distribution System Settings The following notes summarize some critical guidelines regarding WDS configuration. Please read all the notes before proceeding with WDS configuration. Note: When using WDS, be sure to configure WDS settings on both access points participating in the WDS link. You can have only one WDS link between any pair of access points.
Chapter 20: Wireless Distribution System Configuring WDS Settings To configure WDS on this access point, describe each AP intended to receive hand-offs and send information to this AP. Each destination AP needs the following description, as shown in Table 20.1. Table 20.1 Destination Access Point Settings Field Description Local Address Indicates the Media Access Control (MAC) addresses for this access point.
Chapter 20: Wireless Distribution System Example Of Configuring A WDS Link Table 20.1 Destination Access Point Settings Field Description Encryption If you are unconcerned about security issues on the WDS link you may decide not to set any type of encryption. Alternatively, if you have security concerns you can choose between Static WEP, and WPA (PSK). Note: The types of encryption options available here will depend on the settings you have specified on the Security tabbed page.
Chapter 20: Wireless Distribution System Updating Settings The MAC address for MyAP1 (the access point you are currently viewing) will show as the “Local Address” at the top of the page. 3. Configure a WDS interface for data exchange with MyAP2. Start by entering the MAC address for MyAP2 as the “Remote Address” and fill in the rest of the fields to specify the network (guest or internal), security, and so on.

Chapter 22: The 9160 G2 As Base Station Connectivity Options: Base Station Mode Figure 22.5 Overview Of Polling Protocol And Radio Parameters Operating Mode This parameter allows you to set the operating mode of the 9160 G2 as Base Station or RRM. Auto-Startup This parameter enables polling immediately when the 9160 G2 is rebooted. If Auto-Startup is disabled, the 9160 G2 will wait until polling is initialized from the network controller.
Chapter 22: The 9160 G2 As Base Station Connectivity Options: Base Station Mode Shared Channel Shared Channel is only used in Holland to accommodate government requirements. When enabled, it imposes timing restrictions for polling. Every 2 seconds of polling is followed by 0.5 seconds of silence—no polling occurs. Further, if another carrier is detected on the channel, the 9160 G2 will cease radio transmissions on that channel until the path is clear. 22.3.3.
Chapter 22: The 9160 G2 As Base Station Connectivity Options: Base Station Mode Size of Poll Windows The value assigned to this parameter determines the largest message that can be passed between the 9160 G2 and the mobile computer in a normal poll window. The window size can be adjusted to accommodate anywhere from 5 to 32 characters. Larger windows increase the polling period and can increase the response time.
Chapter 22: The 9160 G2 As Base Station Connectivity Options: Base Station Mode Free Window Factor The value entered in this parameter determines if “free window mode” will be used. In free window mode, all mobile computers that are not assigned any other window can use the free window. Entering a value of 0 (zero) in this parameter disables free window mode. Increasing the value of this parameter increases the likelihood of a message being transmitted in the free window.
Chapter 22: The 9160 G2 As Base Station Connectivity Options: Base Station Mode 22.3.3.2 Radio Parameters Sync Delay Important: This parameter should not be changed from its factory setting without a clear understanding of the timing of the radio protocol. Sync Delay specifies the delay between the time of the base station transmission and the first response window, measured in character times.

Chapter 22: The 9160 G2 As Base Station Base Station Configuration Settings Figure 22.6 Base Station Configuration 22.4.1 Base Station Configuration Settings Base stations communicate over the radio link using Psion Teklogix proprietary protocols. Base stations can be connected to network controllers using TCP/IP over Ethernet networks.
Chapter 22: The 9160 G2 As Base Station Base Station Configuration Settings uses the Adaptive Polling/Contention RF protocol (see ‘Radio Protocols’ on page 222 for details on the protocols). The 9160 G2 controls the radio link’s operation and timing. Each base station uses a different radio channel, and mobile computers use cellular switching to roam between stations.
Chapter 22: The 9160 G2 As Base Station RRM Groups Configuration Settings Message Size Message Size determines the largest single message that can be passed to a mobile computer. The range of this parameter is between 32 and 380 characters. (Longer messages are broken into several packets.) For polling protocol base stations, the upper limit is 116. Auto-Startup When this parameter is enabled, the slave base stations will start polling when the master 9160 G2 boots up.
