• Via manual configuration changes—Appropriate when a single, or a small set of changes are to be affected, particularly when that individual SonicPoint requires settings that are different from the profile assigned to its zone.
• Via un-provisioning—Deleting a SonicPoint unit effectively un-provisions the unit, or clears its configuration and places it into a state where it automatically engages the provisioning process anew with its peer SonicOS device. This technique is useful when the profile for a zone is updated or changed, and the change is set for propagation. It can be used to update firmware on SonicPoints, or to simply and automatically update multiple SonicPoint units in a controlled fashion, rather than changing all peered SonicPoints at the same time that can cause service disruptions.

• Does not support 802.11n, only the Channel option is displayed.
• Supports 5GHz 802.11n/a, the Enable DFS Channels option is displayed.
• 2.4GHz 802.11n Only - Allows only 802.11n clients access to your wireless network. 802.11a/b/g clients are unable to connect under this restricted radio mode.
• 2.4GHz 802.11n/g/b Mixed - Supports 802.11b, 802.11g, and 802.11n clients simultaneously. If your wireless network comprises multiple types of clients, select this mode. This is the default.
TIP: For optimal throughput speed solely for 802.11n clients, SonicWALL recommends the 802.11n Only radio mode. Use the 802.11n/b/g Mixed radio mode for multiple wireless client authentication compatibility.
• 2.4GHz 802.11g Only - If your wireless network consists only of 802.11g clients, you may select this mode for increased 802.11g performance. You may also select this mode if you wish to prevent 802.11b clients from associating.
• 5 GHz 802.11n Only - Allows only 802.11n clients access to your wireless network. 802.11a/b/g clients are unable to connect under this restricted radio mode.
• 5 GHz 802.11n/a Mixed - Supports 802.11n and 802.11a clients simultaneously. If your wireless network comprises both types of clients, select this mode.
• 5 GHz 802.11a Only - Select this mode if only 802.11a clients access your wireless network.
3 For 5GHz 802.11a/n only: Optionally check Enable DFS Channels. Enabling Dynamic Frequency Selection (DFS) allows wireless devices to share spectrum with existing radar systems in the 5GHz band.
4 In the SSID field, enter a recognizable string for the SSID of each SonicPoint using this profile. This is the name that will appear in clients’ lists of available wireless connections.
6 Only for 802.11a/g: Select the channel for the radio from the Channel drop-down menu:
• Auto - Allows the appliance to automatically detect and set the optimal channel for wireless operation based on signal strength and integrity. This is the default setting. Use Auto unless you have a specific reason to use or avoid specific channels.

8 For 802.11n only: From the Radio Band drop-down menu, select the band for the 802.11n radio:
• Auto - Allows the appliance to automatically detect and set the optimal channel for wireless operation based on signal strength and integrity. This is the default setting.
•
• Standard - 20 MHz Channel - Specifies that the 802.11n radio will use only the standard 20 MHz channel. When this option is selected, the Channel drop-down menu is displayed instead of the Primary Channel and Secondary Channel drop-down menus.
• Standard Channel - By default, this is set to Auto, which allows the appliance to set the optimal channel based on signal strength and integrity. Optionally, you can select a single channel within the range of your regulatory domain. Selecting a specific a channel can also help with avoiding interference with other wireless networks in the area. The available channels are the same as for 802.11g in Step 6.
• Wide - 40 MHz Channel - Specifies that the 802.11n radio will use only the wide 40 MHz channel. When this option is selected, the Primary Channel and Secondary Channel drop-down menus are displayed:
• Primary Channel - By default, this is set to Auto. Optionally, you can specify a specific primary channel. The available channels are the same as for 802.11a in Step 6
• Secondary Channel - The configuration of this drop-down menu is controlled by your selection for the primary channel; if the primary channel is set to:
• Auto, the secondary channel is also set to Auto.

10 Enable Short Guard Interval: Specifies a short guard interval of 400ns as opposed to the standard guard interval of 800ns.
11 Enable Aggregation: Enables 802.11n frame aggregation, which combines multiple frames to reduce overhead and increase throughput.
TIP: The Enable Short Guard Interval and Enable aggregation options can slightly improve throughput. They both function best in optimum network conditions where users have strong signals with little interference. In networks that experience less than optimum conditions (interference, weak signals, and so on), these options may introduce transmission errors that eliminate any efficiency gains in throughput.

• Key 3: Third static WEP key associated with the key index.
• Key 4: Fourth static WEP key associated with the key index.
1 From the Cipher Type drop-down menu, select the cipher to encrypt your wireless data:
• AES (newer, more secure): AES (Advanced Encryption Standard) is a set of ciphers designed to prevent attacks on wireless networks. AES is available in block ciphers of either 128, 192 or 256 bits depending on the hardware you intend to use with it. In the networking field, AES is considered to be among the most secure of all commonly installed encryption packages.
• TKIP (older, more compatible; default): TKIP (Temporary Key Integrity Protocol) is not actually a cipher, but a set of security algorithms meant to improve the overall safety of WEP (wired equivalent privacy networks). WEP is widely known to have a host of serious security vulnerabilities. TKIP adds a few extra layers of protection to WEP.
• Auto: the appliance chooses the cipher type automatically.
2 In the Group Key Interval (seconds) field, enter the period for which a Group Key is valid, that is, the time interval before the encryption key is changed automatically for added security. The default value is 86400 seconds (24 hours). Setting too low of a value can cause connection issues.

1 Click the Advanced tab.
2 Select Hide SSID in Beacon to have the SSID send null SSID beacons in place of advertising the wireless SSID name. Sending null SSID beacons forces wireless clients to know the SSID in order to connect. This option is unchecked by default.
3 From the Schedule IDS Scan drop-down menu, select a schedule for the IDS (Intrusion Detection Service) scan. Select a time when there are fewer demands on the wireless network to schedule an IDS scan to minimize the inconvenience of dropped wireless connections. You can create your own schedule by selecting Create new schedule or disable the feature by selecting Disabled.
4 From the Data Rate: drop-down menu, select the speed at which the data is transmitted and received. Best automatically selects the best rate available in your area given interference and other factors. This is the default.
5 From the Transmit Power drop-down menu, select the transmission power, which affects the range of the SonicPoint:
• Full Power (default)
•
6 From the Antenna Diversity drop-down menu, select Best, the default. The Antenna Diversity setting determines which antenna the SonicPoint uses to send and receive data. When Best is selected, the SonicPoint automatically selects the antenna with the strongest, clearest signal.
• Best: This is the default setting. When Best is selected, the SonicPoint automatically selects the antenna with the strongest, clearest signal. In most cases, Best is the optimal setting.
• 1: Select 1 to restrict the SonicPoint to use antenna 1 only. Facing the rear of the SonicPoint, antenna 1 is on the left, closest to the power supply.
• 2: Select 2 to restrict the SonicPoint to use antenna 2 only. Facing the rear of the SonicPoint, antenna 2 is on the right, closest to the console port.
7 In the Beacon Interval (milliseconds) field, enter the number of milliseconds between sending out a wireless SSID beacon. This interval represents the amount of time between beacon transmissions. Before a station enters power-save mode, the station needs the beacon interval to know when to wake up to receive the beacon (and learn whether there are buffered frames at the access point).The minimum interval is 20 milliseconds, the maximum is 1000, milliseconds and the default is 100 milliseconds.
8 In the DTIM Interval field, enter the interval, in milliseconds, between the sending of Delivery Traffic Indication Messages (DTIMs) in the beacon. This interval is the maximum number of beacon cycles before unacknowledged network broadcasts are flushed. When using wireless clients that use power management features to sleep, the client must revive at least once during the DTIM period to receive broadcasts. 802.11 power-save mode clients will be alerted of incoming multicast packets.The minimum interval is 1 millisecond, the maximum is 255 milliseconds, and the default is 1 millisecond.
9 In the Fragmentation Threshold (bytes) field, enter the number of bytes of fragmented data you want the network to allow. The fragmentation threshold limits the maximum frame size. This reduces the time required to transmit the frame, and therefore reduces the probability that the frame will be corrupted (at the cost of more data overhead). Fragmented wireless frames increase reliability and throughput in areas with RF interference or poor wireless coverage. Lower threshold numbers produce more fragments.
10 In the RTS Threshold (bytes) field, enter the number of bytes of the Request to Send (RTS) threshold. The RTS threshold specifies the frame size the transmitter must use. Fragmented wireless frames increase reliability and throughput in areas with RF interference or poor wireless coverage. Wireless clients transmitting frames larger than this threshold must issue Request to Send (RTS) and wait for the AP to respond with Clear to Send (CTS). This option also not only can be used to avoid hidden node problems, but also helps prevent mid-air collisions for wireless clients that are not within wireless peer range and cannot detect when other wireless clients are transmitting or in range of the same access point, but may not in range of each other.The minimum value is 256 bytes, the maximum is 2346 bytes, and the default is 2346 bytes. The default value used by many vendors is 2346 bytes. Lower threshold numbers produce more fragments.
11 In the Maximum Client Associations field, enter the maximum number of clients you want each SonicPoint using this profile to support on this radio at one time. The minimum number is 1 client, the maximum is 128 clients, and the default is 32 clients.
12 In the Station Inactivity Timeout (seconds) field, enter the maximum length of wireless client inactivity, in seconds, before access points age out the wireless client. The minimum period is 60 seconds, the maximum is 36000 seconds, and the default number is 300 seconds.
13 From the Preamble Length drop-down menu, select the length of the preamble—the initial wireless communication sent when associating with a wireless host: Long or Short.
14 Select the Enable Short Slot Time checkbox to allow clients to disassociate and reassociate more quickly. Slot time is the amount of time a device waits after a collision before retransmitting a packet. A short slot time increases While selecting this option allows clients to disassociate and reassociate more quickly, it also increases throughput on the 802.11n/g wireless band by shortening the time an access point waits before relaying packets to the LAN. This option is not selected by default.
15 From the WMM (Wi-Fi Multimedia) drop-down menu, select whether a WMM profile is to be associated with this profile:
• Create new WMM profile. The Add Wlan WMM Profile window displays. For information about configuring a WMM profile, see Configuring Wi-Fi Multimedia Parameters .
16 Select the Do not allow 802.11b Clients to Connect checkbox to limit wireless connections to 802.11g and 802.11n clients only. Select this option if you are using Turbo G mode and, therefore, are not allowing 802.11b clients to connect. This option is not selected by default.
17 Click OK.
1 Check the Enable WIDF checkbox to have the SonicPoint N operate as a dedicated WIDP sensor.
