Office Network: Functions as a normal wireless network. Security Mode: Select the security mode of wireless network. If all the hosts are allowed to access the wireless network without password, please select None. For the safety of wireless network, you are suggested to encrypt your wireless network. This device provides two security modes: WPA/WPA2 (Wi-Fi Protected Access) and WPA-PSK/WPA2-PSK (WPA Pre-Shared Key). WPA-PSK/WPA2-PSK is recommended. Settings vary in different security modes as the details is in the following introduction. AP Isolation: Select this checkbox to enable the AP Isolation feature that allows you to confine and restrict all wireless devices on your network from interacting with each other, but still able to access the Internet. This function will be disabled if WDS is enabled. 12
Enable Wireless Network: Check the box to enable this wireless network, allowing the hosts connected to the wireless network to communicate with each other. Security Mode Following is the detailed introduction of security mode: WPA/WPA2 and WPA-PSK/WPA2-PSK.  WPA-PSK/WPA2-PSK Based on pre-shared key. It is characterized by higher safety and simple settings, which suits for common households and small business. WPA-PSK has two versions: WPA-PSK and WPA2-PSK. Figure 4-3 Security Mode WPA-PSK/WPA2-PSK Authentication Type:  Auto: Select WPA or WPA2 automatically based on the wireless station's capability and request.  WPA-PSK: Pre-shared key of WPA.  WPA2-PSK: Pre-shared key of WPA2. Encryption: Select the encryption type, including Auto, TKIP, and AES. The default setting is Auto, which can select TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard) automatically based on the wireless station's capability and request. AES is more secure than TKIP and TKIP is not supported in 802.11n mode. It is recommended to select AES as the encryption type. PSK Password: Configure the PSK password with ASCII or Hexadecimal characters. For ASCII, the length should be between 8 and 63 characters with combination of numbers, letters (case-sensitive) and common punctuations. For Hexadecimal, the length should be 64 characters (case-insensitive, 0-9, a-f, A-F). Group Key Update Period: Specify the group key update period in seconds. The value can be either 0 or 30-8640000 seconds.  WPA/WPA2 13
Based on Radius Server, WPA can assign different password for different users and it is much safer than WPA-PSK. However, its maintenance costs much which is only suitable for enterprise users. At present, WPA has two versions: WPA and WPA2. Figure 4-4 Security Mode WPA/WPA2 Authentication Type: Select one of the following versions:  Auto: Select WPA-PSK or WPA2-PSK automatically based on the wireless station's capability and request.  WPA: Wi-Fi Protected Access.  WPA2: Version 2 of WPA. Encryption: Select the encryption type, including Auto, TKIP, and AES. The default setting is Auto, which can select TKIP (Temporal Key Integrity Protocol) or AES (Advanced Encryption Standard) automatically based on the wireless station's capability and request. AES is more secure than TKIP and TKIP is not supported in 802.11n mode. It is recommended to select AES as the encryption type. RADIUS Server/Port: Enter the IP address/port of the RADIUS server. RADIUS Password: Enter the shared secret of RADIUS server to access the RADIUS server. Group Key Update period: Specify the group key update period in seconds. The value can be either 0 or 30-8640000 seconds. NOTE: Encryption type TKIP is not supported in 802.11n mode. If TKIP is applied in 802.11n mode, the clients may not be able to access the wireless network of the CAP. If TKIP is applied in 11b/g/n mode, the device may work at a low transmission rate. WDS Settings WDS (Wireless Distribution System) is a communication system among multiple wireless local area networks established between APs through wireless connection. In this 14
system, only data frames with four address fields can be transparently forwarded at the link layer. In a WDS network, it is necessary that the root AP supports forwarding of data frames four address fields. If not, only data frames with the ARP/IP/PPPOE protocol can be forwarded among APs. Figure 4-5 WDS Settings Check the box and click OK. The following figure will be shown. Click Yes to enable the WDS feature. There are two ways to select the root AP. Scan or manually enter the parameters. Scan Click the Scan button, the AP list will be shown as below. Select the desired root AP to bridge in the AP list. Figure 4-6 AP List After selecting the desired root AP, the WDS settings page will be shown as below. If the root AP is encrypted, you should enter the PSK password manually. Click OK to finish the settings. 15
Figure 4-7 WDS Settings Manually You should manually enter the parameters of the root AP. Click OK to finish the settings. WDS: Check the box to enable WDS feature. SSID: The SSID of the AP your device is going to connect to as a client. BSSID: The BSSID of the AP your device is going to connect to as a client. Security Mode: This option should be chosen according to the AP's security configuration. It is recommended that the security type is the same as your AP's security type. Select the encryption type, including None and WPA-PSK/WPA2-PSK. The default setting is None. Please refer to Security Mode for details. Advanced Settings You can configure the advanced settings in this section. Improper configuration would degrade the CAP’s wireless performance. With no special requirement, it is recommended to keep the default settings. Figure 4-8 Advanced Settings Wireless Mode: Select the protocol standard for the wireless network. 16
It is recommended to select 802.11b/g/n, in which way clients supporting any one of these modes can access your wireless network. Channel Bandwidth: Select the channel bandwidth of this device including 20MHz and 40MHz. The default setting is Auto, which will select the proper bandwidth automatically according to the network need. According to IEEE 802.11n standard, using a higher bandwidth can increase wireless throughput. However, users may choose lower bandwidth due to the following reasons: 1. To increase the available number of channels within the limited total bandwidth. 2. To avoid interference from overlapping channels occupied by other devices in the environment. 3. Lower bandwidth can concentrate higher transmit power, increasing stability of wireless links over long distances. Channel: This field determines which operating frequency will be used. The default channel is set to Auto, so the AP will choose the best channel automatically. It is not necessary to change the wireless channel unless you notice interference problems with another nearby access point. Transmit Power: You can use the slider or manually enter the transmit power value. The maximum transmit power may vary among different countries or regions. SSID Isolation: With this option enabled, the hosts connected to different wireless networks cannot communicate with each other. Beacon Interval: Beacons are transmitted periodically by the device to announce the presence of a wireless network for the clients. Enter a time interval between 40 and 1000 in milliseconds to determine the duration between beacon packets that are transmitted periodically by the device to synchronize the wireless network. The default is 100 milliseconds. Maximum Users: Specify the maximum users that allowed to connect to the CAP. Forbid stations with a signal strength lower than ( ) dBm from accessing the AP: Enable or disable the access rules. Set the minimum signal strength for a new client to be allowed to access the network. Values from -95 to 0 dBm are valid. The default value is -75 dBm. It is recommended the maximum number is less than -40 dBm. When clients attempt to connect to the AP with lower signal strength than the threshold value (for example due to obstacles or long distances), they will be denied access to the AP. 17
Discard stations with a signal strength lower than ( ) dBm: Enable or disable the discard rules. Set the minimum signal strength in which the AP will discard a connected client. Values from -95 to 0 dBm are valid. The default value is -75dBm. It is recommended the maximum number is less than -40 dBm. When the signal strength of the connected client is lower than the threshold value (for example due to obstacles or long distances), the client will be discarded by the AP. 18
