As you can see, this management interface provides six main options in the black bar above, which are Status, System, Wireless, Firewall, Management and Tools. Figure 11 Main Page The username and password are case-sensitive, and the password should be no more than 19 characters! Note: 註解 [A3]: 我怎麼算出來是六個…
Basic System Settings For users who use the IEEE 802.11a/n Wireless Outdoor CPE for the first time, it is recommended that you begin configuration from “Basic Settings” in “System” shown below: Figure 7 Basic System Settings Basic Settings Device Name: Specify the device name, which is composed of no more than 15 characters with (0-9), (A-Z), (a-z) or (-). Network Mode: Specify the network mode, including Bridge and Router. It is easy to configure parameters in Bridge Mode; however, users must pay extra attention to the way they configure the device when it is set to Router Mode. For details, please refer to “IP Settings (Router)”. Ethernet Data Rate: Specify the transmission rate of data. Default is Auto. Country Region: The availability of some specific channels and/or operational frequency bands is country dependent. Secondary RJ45 Power: The secondary Ethernet port (labeled LAN 2) is for IP video integration. To use it you need to enable the secondary port via WEB UI in advance before connecting with the IP camera. Spanning Tree: Spanning Tree Protocol (STP) is a link management protocol for AP which provides path redundancy while preventing loops in a network. STP allows only one active path
at a time between the access points but establish the redundant link as a backup if the initial link fails. STP Forward Delay: STP Forward Delay is the time spent in detecting and learning network tree topology state before entering the forward state. Default time value is 1 sec. TCP/IP Settings Open “TCP/IP Settings (Bridge)” in “System” as below to configure the parameters for LAN which connects to the LAN port of the CPE. In this page, users may change the settings for IP Address, Subnet Mask, and DHCP Server. Figure 13 TCP/IP Settings (Bridge) Obtain IP Address Automatically: If a DHCP server exists in your network, you can check this option, thus the IEEE 802.11a/n Wireless Outdoor CPE is able to obtain IP settings automatically from that DHCP server. When the IP address of the CPE is changed, the clients on the network often need to wait for a while or even reboot before they can access the new IP address. For an immediate access to the bridge, please flush the netbios cache on the client computer by running the “nbtstat –r” command before using the device name of the CPE to access its Web Management page. Note: 註解 [A4]: S 沒畫到下底線
Use Fixed IP Address: Check this option. You have to specify a static IP address, subnet mask, default gateway and DNS server for the CPE manually. Make sure the specified IP address is unique on your network in order to prevent IP conflict. If the IEEE 802.11a/n Wireless Outdoor CPE is configured as Router mode, you need to configure some additional TCP/IP parameters for accessing the Internet. Figure 14 TCP/IP Settings (Router) WAN Settings: Specify the Internet access method to Static IP, DHCP or PPPOE. Users must enter WAN IP Address, Subnet Mask, Gateway settings provided by your ISPs. LAN Settings: When DHCP Server is disabled, users can specify IP address and subnet mask for the CPE manually. Make sure the specified IP address is unique on your network in order to prevent IP conflict. When DHCP Server is enabled, users may specify DHCP IP Address Range, DHCP Subnet Mask, DHCP Gateway and Lease Time (15-44640 minutes).
In AP mode, the IEEE 802.11a/n Wireless Outdoor CPE must establish connection with another wireless device before it is set to Router mode. In Router mode, it is impossible for users to access device via wired port, for WAN is on wired port and LAN is on wireless port. Users can access device through the wireless device connected with the CPE. In wireless client mode, users can access the CPE via its wired port, for WAN is on wireless port and LAN is on wired port when device is set to Router mode. Bridge mode and AP Repeater mode are similar to AP mode when device is set to Router mode; WAN is on wired port and LAN is on wireless port. Thus users must also connect the CPE with another wireless device before it is set to Router mode and access the CPE via the connected wireless device. Time Settings Compliant with NTP, the IEEE 802.11a/n Wireless Outdoor CPE is capable of keeping its time in complete accord with the Internet time. Make configuration in “Time Settings” from “System”. To use this feature, check “Enable NTP Client Update” in advance. Figure 15 Time Settings Current Time Display the present time in Yr, Mon, Day, Hr, Min and Sec. Warning:
Time Zone Select Select the time zone from the dropdown list. NTP Server Select the time server from the “NTP Server” dropdown list or manually input the IP address of available time server into “Manual IP”. Hit “Apply” to save settings. RADIUS Settings RADIUS (Remote Authentication Dial-In User Service) is a server for remote user authentication and accounting; playing a central role in the network in providing the capabilities of authenticating, authorizing, accounting, auditing, alarming and etc. It allows an organization to maintain user profiles in a central database that all remote servers can share. Open “RADIUS Settings” in “System” to make RADIUS configuration. Figure 168 RADIUS Settings Authentication RADIUS Server This is for RADIUS authentication. It can communicate with RADIUS through IP Address, Port and Shared Secret. IP Address: Enter the IP address of the Radius Server; Port: Enter the port number of the Radius Server;
Shared Secret: This secret, which is composed of no more than 31 characters, is shared by the AP and RADIUS during authentication. Re-authentication Time: Set the time interval between two authentications. Global-Key Update: Check this option and specify the time interval between two global-key updates. Firewall Settings The firewall is a system or group of systems that enforce an access control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from an un-trusted network. The IEEE 802.11a/n Wireless Outdoor CPE has capabilities of Source IP Filtering, Destination IP Filtering, Source Port Filtering, Destination Port Filtering, Port Forwarding as well as DMZ. This is available only under Router Mode. Source IP Filtering: The source IP filtering gives users the ability to restrict certain types of data packets from your local network to Internet through the IEEE 802.11a/n Wireless Outdoor CPE. Use of such filters can be helpful in securing or restricting your local network. Figure 17 Source IP Filtering Destination IP Filtering: The destination IP filtering gives you the ability to restrict the computers in LAN from accessing certain websites in WAN according to specified IP addresses. Check the
“Enable Destination IP Filtering” checkbox and enter the IP address of the clients to be restricted. Hit Apply to make the setting take effect. Figure 18 Destination IP Filtering Source Port Filtering: The source port filtering enable you to restrict certain ports of data packets from your local network to Internet through the IEEE 802.11a/n Wireless Outdoor CPE. Use of such filters can be helpful in securing or restricting your local network. Figure 19 Source Port Filtering
Destination Port Filtering: The destination port filtering enables you to restrict certain ports of data packets from your local network to Internet through the IEEE 802.11a/n Wireless Outdoor CPE. Use of such filters can be helpful in securing or restricting your local network. Figure 20 Destination Port Filtering Port Forwarding: The port forwarding allows you to automatically redirect common network services to a specific machine behind the NAT firewall. These settings ne are only necessary if you wish to host some sort of server like a web server or mail server on the private local network behind the router’s NAT firewall.
Figure 21 Port Forwarding DMZ: A Demilitarized Zone is used to provide Internet services without sacrificing unauthorized access to its local private network. Typically, the DMZ host contains devices accessible to the Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers. Figure 22 DMZ
Basic Wireless Settings Open “Basic Settings” in “Wireless” as below to make basic wireless configuration. Figure 23 Basic Wireless Settings Disable Wireless LAN Interface Check this option to disable WLAN interface, then the wireless module of the CPE will stop working and no wireless device can connect to it. Wireless Mode Four operating modes are available on the IEEE 802.11a/n Wireless Outdoor CPE. AP: The IEEE 802.11a/n Wireless Outdoor CPE establishes a wireless coverage and receives connectivity from other wireless devices. Wireless Client: The IEEE 802.11a/n Wireless Outdoor CPE is able to connect to the AP and thus join the wireless network around it. Bridge: The IEEE 802.11a/n Wireless Outdoor CPE establishes wireless connectivity with other APs by keying in remote MAC address. Please refer to the “WDS Setting” for detailed configuration. AP Repeater: The IEEE 802.11a/n Wireless Outdoor CPE servers as AP and Bridge concurrently. In other words, it can provide connectivity services for CPEs under WDS mode.
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 cannot exceed 32 characters. 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 802.11a/n Wireless Outdoor CPE, so that malicious attack by some illegal STA could be avoided. 802.11 Mode The IEEE 802.11a/n Wireless Outdoor CPE can communicate with wireless devices of 802.11n or 802.11a/n. You can also select Auto and make it work under an appropriate wireless mode automatically. 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. Channel Number Channel varies much as the available band differs from country to country. Select a proper operating channel in the drop-down list according to your situation. Antenna By default, the IEEE 802.11a/n Wireless Outdoor CPE uses its built-in antenna for directional transmission; Output Power 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. Usually “Full” is preferred.
Data Rate Usually “Auto” is preferred. Under this rate, the Wireless Outdoor CPE will 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. 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. Extension Channel Protection Mode This is to avoid conflict with other wireless network and boost the ability of your device to catch all legacy devices 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 CPE while displays the one of associated wireless client or the MAC address designated manually. Site Survey Under wireless client mode, the IEEE 802.11a/n Wireless Outdoor CPE 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 wireless networks around. Select the AP you would like to connect and click “Selected” to establish connection. The wireless site survey window can also be viewed by opening the “Site Survey” page in “Tools”.
Figure 24 Site Survey
Chapter 4 Advanced Settings Advanced Wireless Settings Open “Advanced Settings” in “Wireless” to make advanced wireless settings. Figure 25 Advanced Wireless Settings 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. A-MPDU/A-MSDU Aggregation The data rate of your CPE 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.
RTS Threshold The IEEE 802.11a/n Wireless Outdoor CPE 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. IGMP Snooping 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. Wireless Separation Wireless separation is an ideal way to enhance the security of network transmission. Under the mode except wireless client mode, enable “Wireless Separation” can prevent the communication among associated wireless clients. 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. Max. Station Num Available only under AP mode, it defines the maximum amount of wireless clients allowed to be connected. Space in Meter/ACK Timeout To decrease the chances of data retransmission at long distance, the IEEE 802.11a/n Wireless Outdoor CPE 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. Note:
Wireless Security Settings To prevent unauthorized radios from accessing data transmitting over the connectivity, the IEEE 802.11a/n Wireless Outdoor CPE provides you with rock solid security settings. Security Settings Open “Security Settings” in “Wireless” as below: Figure 26 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. Legacy 802.1x: As an IEEE standard for port-based Network Access Control, 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: 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: As a new version of WPA, only all the clients support WPA2, can it be available. If it is selected, AES encryption and RADIUS server is 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. 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: 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 setting the same Authentication, Data Encryption and Key in the CPE and other associated wireless devices, can the communication be established! Note:
Access Control The Access Control appoints the authority to wireless client on accessing the IEEE 802.11a/n Wireless Outdoor CPE, thus a further security mechanism is provided. This function is available only under AP mode. Open “Access Control” in “Wireless” as below.

Chapter 7 Troubleshooting This chapter provides troubleshooting procedures for basic problems with the CPE. For warranty assistance, contact your service provider or distributor for the process. Q 1. How to know the MAC address of the IEEE 802.11a/n Wireless Outdoor CPE? MAC Address distinguishes itself by the unique identity among network devices. There are two ways available to know it.  Each device has a label posted with the MAC address. Please refer below. Figure 9 MAC Address  On the CPE’s Web-based management interface, you can view the MAC Address from “View Basic Information”. Q 2. What if I would like to reset the unit to default settings? You may restore factory default settings in “Configuration File” from “Management”. Q 3. What if I would like to backup and retrieve my configuration settings? You may do the backup by generating a configuration file or retrieve the settings you have backed up previously in “Configuration File” from “Management”. Q 4. What if I can not access the Web-based management interface? Please check the followings:  Check whether the power supply is OK; Try to power on the unit again.  Check whether the IP address of PC is correct (in the same network segment as the unit);  Login the unit via other browsers such as Firefox.  Hardware reset the unit.
Q 5. In wireless client mode, what if the wireless connection is not stable after associating with an AP?  Since the CPE comes with a built-in directional antenna, it is recommended make it face to the direction where the AP is to get the best connection quality.  In addition, you can start “Site Survey” in “Wireless Basic Settings” to check the signal strength. If it is weak or unstable (The smaller the number is, the weaker the signal strength is.), please join other available AP for better connection.
