Operation Mode Four operating modes are available in IEEE 802.11n ZAC Access Point when acts as a FAT AP. AP: The IEEE 802.11n ZAC Access Point establishes a wireless coverage and receives connectivity from other wireless devices. Wireless Client: The IEEE 802.11n ZAC Access Point is able to connect to the AP and thus join the wireless network around it. Bridge: The IEEE 802.11n ZAC Access Point establishes wireless connectivity with other APs by keying in remote MAC address. Please refer to the “WDS Settings” for detailed configuration. AP Repeater: The IEEE 802.11n ZAC Access Point servers as AP and Bridge concurrently. In other words, the IEEE 802.11n ZAC Access Point can provide connectivity services for CPEs under Bridge mode.
P. 84 Wireless Network Name (SSID) This wireless network name is shared among all associated devices in your wireless network. Keep it identical on all those devices. Note that the SSID is case-sensitive and can not exceed 32 characters. Broadcast SSID Under AP mode, hiding network name is necessary when you are in a wireless environment that may have potential risk. By disabling broadcast SSID, the STA can not scan and find IEEE 802.11n ZAC Access Point, so that malicious attack by some illegal STA could be avoided. 802.11 Mode The IEEE 802.11n ZAC Access Point can communicate with wireless devices of 802.11b/g or 802.11b/g/n. HT Protect Enable HT (High Throughput) protect to ensure HT transmission with MAC mechanism. Under 802.11n mode, wireless client can be divided into HT STA and Non-HT STA, among which the one with HT protect enabled gets higher throughput. Frequency/Channel Channel varies much as the available band differs from country to country. Extension Channel Only applicable to AP, AP Repeater, and 40MHz channel width) indicates the use of channel bonding that allows the IEEE 802.11n ZAC Access Point to use two channels at once. Two options are available: Upper Channel and Lower Channel. Channel Mode Four levels are available: 5MHz, 10MHz, 20MHz and 40MHz. The last one can enhance data throughput, but it takes more bandwidth, thus it might cause potential interference. Maximum Output Power (per chain): Specify the signal transmission power. The higher the output power is, the wider the signal can cover, but the power consumption will be greater accordingly. The output power will vary depending on each country’s regulation. Data Rate Usually “Auto” is preferred. Under this rate, the IEEE 802.11n ZAC Access Point will
P. 85 automatically select the highest available rate to transmit. In some cases, however, like where there is no great demand for speed, you can have a relatively-low transmit rate for compromise of a long distance. Extension Channel Protection Mode This is to avoid conflict with other wireless network and boost the ability of your device to catch all 802.11g transmissions. However, it may decrease wireless network performance. Compared to CTS-Self; the transmission amount of CTS-RTS is much lower. Enable MAC Clone Available only under wireless client mode, it hides the MAC address of the AP while displays the one of associated wireless client or the MAC address designated manually. Site Survey Under wireless client mode, the IEEE 802.11n ZAC Access Point is able to perform site survey, through which, information on the available access points will be detected. Open “Basic Settings” in “Wireless”, by clicking the “Site Survey” button beside “Wireless Mode” option, the wireless site survey window will pop up with a list of available AP in the vicinity. Select the AP you would like to connect and click “Selected” to establish connection. VAP Profile Settings Available in AP mode, the IEEE 802.11n ZAC Access Point allows up to 16 virtual SSIDs on a single BSSID and to configure different profile settings such as security and VLAN ID to each SSID.

P. 86 virtual AP, you may check the Enable box of the profile and click on the profile (eg. Profile 2) to configure wireless and security settings. Hit Apply to active the profile. Basic Setting Profile Name: Name of the VAP profile Wireless Network Name: Enter the virtual SSID for the VAP Broadcast SSID: In AP mode, hiding network name is necessary when you are in a wireless environment that may have potential risk. By disabling broadcast SSID, the STA cannot scan and find the IEEE 802.11n ZAC Access Point, so that malicious attack by some illegal STA could be avoided. Wireless Separation: Wireless separation is an ideal way to enhance the security of network
P. 87 transmission. Under the mode except wireless client mode, enable “Wireless Separation” can prevent the communication among associated wireless clients. WMM Support: WMM (Wi-Fi Multimedia) is a subset of 802.11e. It allows wireless communication to define a priority limit on the basis of data type under AP mode only, thus those time-sensitive data, like video/audio data, may own a higher priority than common one. To enable WMM, the wireless client should also support it Max. Station Number: By checking the “Max. Station Num” the ZAC Access Point will only allow up to 32 wireless clients to associate with for better bandwidth for each client. By disabling the checkbox the ZAC Access Point will allow up to 128 clients to connect, but it is likely to cause network congestion or poor performance. Security Setting: To prevent unauthorized radios from accessing data transmitting over the connectivity, the IEEE 802.11a/n ZAC Access Point provides you with rock solid security settings. Network Authentication Open System: It allows any device to join the network without performing any security check. Shared Key: Data encryption and key are required for wireless authentication (Not available in Bridge/AP Repeater mode). Legacy 802.1x: It provides the rights to access the wireless network and wired Ethernet. With User and PC identity, centralized authentication as well as dynamic key management, it controls the security risk of wireless network to the lowest. To serve the 802.1x, at least one EAP type should be supported by the RADIUS Server, AP and wireless client. WPA with RADIUS: Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. With warrant (username, password and etc.) offered by user, this kind of authentication can be realized with specific RADIUS server. This is the common way to be adopted in large enterprise network. WPA2 with RADIUS: WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. If it is selected, AES encryption and RADIUS server are required. WPA&WPA2 with RADIUS: It provides options of WPA (TKIP) or WPA2 (AES) for the client. If it is selected, the data encryption type must be TKIP + AES and the RADIUS server must be set.
P. 88 If Radius relevant authentication type is selected, please go to Wireless  Radius Settings for further radius server configuration. WPA-PSK: It is a simplified WPA mode with no need for specific authentication server. In this so-called WPA Pre-Shared Key, all you have to do is just pre-enter a key in each WLAN node and this is the common way to be adopted in large and middle enterprise as well as residential network. WPA2-PSK: As a new version of WPA, only all the clients support WPA2, can it be available. If it is selected, the data encryption can only be AES and the passphrase is required. WPA-PSK&WPA2-PSK: Available in AP mode, it provides options of WPA (TKIP) or WPA2 (AES) encryption for the client. If it is selected, the data encryption can only be TKIP + AES and the passphrase is required. Data Encryption If data encryption is enabled, the key is required and only sharing the same key with other wireless devices can the communication be established. None: Available only when the authentication type is open system. 64 bits WEP: It is made up of 10 hexadecimal numbers. 128 bits WEP: It is made up of 26 hexadecimal numbers. 152 bits WEP: It is made up of 32 hexadecimal numbers. TKIP: Temporal Key Integrity Protocol, which is a kind of dynamic encryption, is co-used with WPA-PSK, etc. AES: Advanced Encryption Standard, it is usually co-used with WPA2-PSK, WPA, WPA2, etc. TKIP + AES: It allows for backwards compatibility with devices using TKIP. We strongly recommend you enable wireless security on your network! Only the same Authentication, Data Encryption and Key among the IEEE 802.11n ZAC Access Point and wireless clients can the communication be established! Note: Note:
P. 89 VLAN If your network uses VLANs, you can assign one SSID to a VLAN, and client devices using the SSID are grouped in that VLAN. To allow users on the VLAN to access the WEB page of the IEEE 802.11a/n ZAC Access Point, you need to enable “Enable 802.1Q VLAN” and assign a management VLAN ID for your device. Make sure the assigned management VLAN ID is identical to your network VLAN ID to avoid failures of accessing the Web page of the IEEE 802.11n ZAC Access Point. Advanced Settings Open “Advanced Settings” in “Wireless” to make advanced wireless settings. A-MPDU/A-MSDU Aggregation
P. 90 The data rate of your AP except wireless client mode could be enhanced greatly with this option enabled; however, if your wireless clients don’t support A-MPDU/A-MSDU aggregation, it is not recommended to enable it. Short GI Under 802.11n mode, enable it to obtain better data rate if there is no negative compatibility issue.
P. 91 RTS Threshold The IEEE 802.11n ZAC Access Point sends RTS (Request to Send) frames to certain receiving station and negotiates the sending of a data frame. After receiving an RTS, that STA responds with a CTS (Clear to Send) frame to acknowledge the right to start transmission. The setting range is 0 to 2346 in byte. Setting it too low may result in poor network performance. Leave it at its default of 2346 is recommended. Fragmentation Length Specify the maximum size in byte for a packet before data is fragmented into multiple packets. Setting it too low may result in poor network performance. Leave it at its default of 2346 is recommended. Beacon Interval Specify the frequency interval to broadcast packets. Enter a value between 20 and 1024. DTIM Interval DTIM, which stands for Delivery Traffic Indication Message, is contained in the data packets. It is for enhancing the wireless transmission efficiency. The default is set to 1. Enter a value between 1 and 255. Preamble Type It defines some details on the 802.11 physical layer. “Long” and “Auto” are available. IGMP Snooping Available in AP/Router mode, IGMP snooping is the process of listening to IGMP network traffic. By enabling IGMP snooping, the AP will listen to IGMP membership reports, queries and leave messages to identify the ports that are members of multicast groups. Multicast traffic will only be forwarded to ports identified as members of the specific multicast group or groups. RIFS RIFS (Reduced Interframe Spacing) is a means of reducing overhead and thereby increasing network efficiency. Link Integration Available under AP/Bridge/AP repeater mode, it monitors the connection on the Ethernet port by checking “Enabled”. It can inform the associating wireless clients as soon as the disconnection occurs.
P. 92 TDM Coordination Stands for “Time-Division Multiplexing Technique”, this resource reservation control mechanisms can avoid packet collisions and send the packets much more efficiently allowing for higher effective throughput rates. This function is only available in AP/CPE mode. It is highly recommended to enable TDM coordination when there are multiple CPEs needed to connect to the AP in your application. LAN2LAN CPE LAN2LAN CPE mode enables packet forwarding at layer 2 level. It is fully transparent for all the Layer2 protocols. Space in Meter To decrease the chances of data retransmission at long distance, the IEEE 802.11n ZAC Access Point can automatically adjust proper ACK timeout value by specifying distance of the two nodes. Flow Control It allows the administrator to specify the incoming and outgoing traffic limit by checking “Enable Traffic Shaping”. This is only available in Router mode. We strongly recommend you leave most advanced settings at their defaults except “Distance in Meters” adjusted the parameter for real distance; any modification on them may negatively impact the performance of your wireless network. Access Control The Access Control appoints the authority to wireless client on accessing IEEE 802.11n ZAC Access Point, thus a further security mechanism is provided. This function is available only under AP/Router mode. Open “Access Control” in “Wireless Settings” as below. Note:
P. 93 Profile Selection: Select the VAP network you would like to enable access control.
