17 Ch 2. First Time Configuration Before Start to Configure There are two ways to configure the device, one is through web-browser, and the other is through Secure Shell CLI interface. To access the configuration interfaces, make sure you are using a computer connected to the same network as the device. The default IP address of the device is 192.168.2.254, and the subnet-mask is 255.255.255.0. The device has three operation modes (Router/Bridge/WISP). In bridge mode, also known as AP Client, you can access the device by both WLAN (Wireless Local Area Network) and wired LAN. And in router/WISP modes, the device can be accessed by both WLAN and WAN. The default IP addresses for the device are 192.168.2.254(for InternetEthernetHUB/SWITCHADSLGroundOutdoor IndoorPower InjectorPower SupplyRJ-45 48V inAntenna

18LAN), 172.1.1.1(for WAN), so you need to make sure the IP address of your PC is in the same subnet as the device, such as 192.168.2.X (for LAN), 172.1.1.X (for WAN). Please note that the DHCP server inside the device is default to up and running. Do not have multiple DHCP servers in your network environment, otherwise it will cause abnormal situation. We also provide an auto-discovery tool which is for finding out the IP of the device. In case, you’ve forgot the IP of the device or the IP of the device has been changed, you can use the tool to find out the IP of the device even your PC is not in the same subnet as the device is. Knowing the Network Application The device can act as the following roles, and it supports WDS (Wireless Distribution System) function.  Access Point  WDS (Wireless Repeater)  Bridge/Router  WISP  AP Client The device provides 3 different operation modes and the wireless radio of device can act as AP/Client/WDS. The operation mode is about the communication mechanism between the wired Ethernet NIC and wireless NIC, the following is the types of operation mode. Router The wired Ethernet (WAN) port is used to connect with ADSL/Cable modem and the wireless NIC is used for your private WLAN. The NAT is existed between the 2 NIC and all the wireless clients share the same public IP address through the WAN port to ISP. The default IP configuration for WAN port is static IP. You can access the web server of device through the default WAN IP address 172.1.1.1 and modify the setting base on your ISP requirement. Bridge The wired Ethernet and wireless NIC are bridged together. Once the mode is selected, all the WAN related functions will be disabled. WISP (Wireless ISP) This mode can let you access the AP of your wireless ISP and share the same public IP address from your ISP to the PCs connecting with the wired Ethernet port of the device.

19To use this mode, first you must set the wireless radio to be client mode and connect to the AP of your ISP then you can configure the WAN IP configuration to meet your ISP requirement. The wireless radio of the device acts as the following roles. AP (Access Point) The wireless radio of device serves as communications “hub” for wireless clients and provides a connection to a wired LAN. AP Client This mode provides the capability to connect with the other AP using infrastructure/Ad-hoc networking types. With bridge operation mode, you can directly connect the wired Ethernet port to your PC and the device becomes a wireless adapter. And with WISP operation mode, you can connect the wired Ethernet port to a hub/switch and all the PCs connecting with hub/switch can share the same public IP address from your ISP. WDS (Wireless Distribution System) This mode serves as a wireless repeater; the device forwards the packets to another AP with WDS function. When this mode is selected, all the wireless clients can’t survey and connect to the device. The device only allows the WDS connection. WDS+AP This mode combines WDS plus AP modes, it not only allows WDS connections but also the wireless clients can survey and connect to the device. The following table shows the supporting combination of operation and wireless radio modes. Bridge Router WISP AP V V X WDS V V X Client V X V AP+WDS V V X Hereafter are some topologies of network application for your reference.

AP+WDS Support both AP and WDS functions, the wireless clients and devices with WDS function supported can survey and connect to it. Network Type: Infrastructure: This type requires the presence of 802.11b/g Access Point. All communication is done via the Access Point. EthernetAPAP Client #2AP Client #1 Ad Hoc: This type provides a peer-to-peer communication between wireless stations. All the communication is done from Client to Client without any Access Point involved. Ad Hoc networking must use the same SSID and channel for establishing the wireless connection.

22PC #3 PC #2AP Client #1AP Client #2AP Client #3PC #1 In client mode, the device can’t support the Router mode function including Firewall and WAN settings. SSID: The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. Multiple access point/bridges on a network or sub-network can use the same SSID. SSIDs are case sensitive and can contain up to 32 alphanumeric characters. Do not include spaces in your SSID. Channel Number: The following table is the available frequencies (in MHz) for the 2.4-GHz radio: Channel No. Frequency Country Domain 1 2412 Americas, EMEA, Japan, and China 2 2417 Americas, EMEA, Japan, and China 3 2422 Americas, EMEA, Japan, Israel, and China 4 2427 Americas, EMEA, Japan, Israel, and China 5 2432 Americas, EMEA, Japan, Israel, and China 6 2437 Americas, EMEA, Japan, Israel, and China 7 2442 Americas, EMEA, Japan, Israel, and China 8 2447 Americas, EMEA, Japan, Israel, and China 9 2452 Americas, EMEA, Japan, Israel, and China 10 2457 Americas, EMEA, Japan, and China 11 2462 Americas, EMEA, Japan, and China 12 2467 EMEA and Japan 13 2472 EMEA and Japan 14 2484 Japan only ※ EMEA (Europe, the Middle East and Africa). When set to “Auto”, the device will find the least-congested channel for use. Associated Client: Show the information of active wireless client stations that connected to the device. REMARK IEEE 802.11b or 802.11g operation of this product in the U.S.A. is firmware-limited to channels 1 through 11.

23 Advanced Settings These settings are only for more technically advanced users who have sufficient knowledge about wireless LAN. These settings should not be changed unless you know what effect the changes will have on your device. The default setting is optimized for the normal operation. For specific application, setting configuration will required highly attention to reach optimistic condition. Note： Any unreasonable value change to default setting will reduce the throughput of the device.

24 Authentication Type The device supports two Authentication Types “Open system” and “Shared Key”. When you select “Share Key”, you need to setup “WEP” key in “Security” page (See the next section). The default setting is “Auto”. The wireless client can associate with the device by using one of the two types. Fragment Threshold The fragmentation threshold determines the size at which packets are fragmented (sent as several pieces instead of as one block). Use a low setting in areas where communication is poor or where there is a great deal of radio interference. This function will help you to improve the network performance. RTS Threshold The RTS threshold determines the packet size at which the radio issues a request to send (RTS) before sending the packet. A low RTS Threshold setting can be useful in areas where many client devices are associating with the device, or in areas where the clients are far apart and can detect only the device and not each other. You can enter a setting ranging from 0 to 2347 bytes. Beacon Interval The beacon interval is the amount of time between access point beacons in mini-seconds. The default beacon interval is 100. ACK Timeout The default ACK timeout is 0. You may need to change this value due to the environment or distance. Client Expired Time

26This ensures that 802.11g stations are backwards compatible with legacy 802.11b stations. With 802.11g protection enabled, a CTS will be used to lock out 802.11b stations while the 802.11g station is transmitting. While this does allow backwards compatibility with legacy 802.11b stations, it should be disabled in a pure 802.11g environment, as it will have a significant impact on 802.11g performance (as high as 50% decrease in throughput). Block WLAN Relay (Isolate Client) The device supports isolation function. If you are building a public Wireless Network, enable this function can provide better security. The device will block packets between wireless clients (relay). All the wireless clients connected to the device can’t see each other. Aggregation Mode Not applicable for WLAN 1. Tx Burst Mode Not applicable for WLAN 1.

The default security setting of the encryption function is disabled. Choose your preferred security setting depending on what security function you need. WEP Encryption Setting Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized access to your wireless network. The WEP setting must be as same as each client in your wireless network. For more secure data transmission, you can change encryption type to “WEP” and click the “Set WEP Key” button to open the “Wireless WEP Key setup” page.

27 When you decide to use the WEP encryption to secure your WLAN, please refer to the following setting of the WEP encryption:  64-bit WEP Encryption：64-bit WEP keys are as same as the encryption method of 40-bit WEP. You can input 10 hexadecimal digits (0~9, a~f or A~F) or 5 ACSII chars.  128-bit WEP Encryption：128-bit WEP keys are as same as the encryption method of 104-bit WEP. You can input 26 hexadecimal digits (0~9, a~f or A~F) or 10 ACSII chars.  The Default Tx Key field decides which of the four keys you want to use in your WLAN environment. WEP Encryption with 802.1x Setting The device supports external RADIUS Server that can secure networks against unauthorized access. If you use the WEP encryption, you can also use the RADIUS server to check the admission of the users. By this way every user must use a valid account before accessing the Wireless LAN and requires a RADIUS or other authentication server on the network. An example is shown as following.

28 EthernetRADIUS ServerWireless StationAP You should choose WEP 64 or 128 bit encryption to fit with your network environment first. Then add user accounts and the target device to the RADIUS server. In the device , you need to specify the IP address、Password (Shared Secret) and Port number of the target RADIUS server.

40Not applicable for WLAN 2. MTU Size Maximum Transmission Unit, the default MTU size is 1500. The MTU setting controls the maximum Ethernet packet size your PC will send. Why a limit? Because although larger packets can be constructed and sent, your ISP and Internet backbone routers and equipment will fragment any larger than their limit, then these parts are re-assembled by the target equipment before reading. This fragmentation and re-assembly is not optimal. You may need to change the MTU for optimal performance of your wireless LAN traffic. Data Rate The standard IEEE 802.11a supports 6, 9, 12, 18, 24, 36, 48 and 54 Mbps data rates. You can choose the rate that the device uses for data transmission. The default value is “auto”. The device will use the highest possible selected transmission rate. Preamble Type The preamble is part of the 802.11 frame and is PHY dependant. All 802.11a systems support the long preamble. The short preamble (optional) maybe used to improve throughput when all stations on the network support the short preamble. Broadcast SSID Broadcasting the SSID will let your wireless clients find the device automatically. If you are building a public Wireless Network, disable this function can provide better security. Every wireless stations located within the coverage of the device must connect this device by manually configure the SSID in your client settings. IAPP (Inter-Access Point Protocol) Not applicable for WLAN 2. 802.11g Protection Not applicable for WLAN 2. Block WLAN Relay (Isolate Client) The device supports isolation function. If you are building a public Wireless Network, enable this function can provide better security. The device will block packets between wireless clients (relay). All the wireless clients connected to the device can’t see each other. Aggregation Mode This is a proprietary Ralink (802.11a chipset in the DLB70xx) aggregation setting that allows for jumbo frames consisting of multiple smaller frames that increases throughput between Ralink stations. Tx Burst Mode This is a proprietary Ralink (802.11a chipset in the device) burst setting and allows very small networks (1~3 clients) to transmit at higher speeds. In larger networks, this will result in degraded performance.

41Configuring Wireless Security This device provides complete wireless security function include WEP, 802.1x, WPA-TKIP, WPA2-AES and WPA2-Mixed in different mode (see the Security Support Table). The default security setting of the encryption function is disabled. Choose your preferred security setting depending on what security function you need. WEP Encryption Setting Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized access to your wireless network. The WEP setting must be as same as each client in your wireless network. For more secure data transmission, you can change encryption type to “WEP” and click the “Set WEP Key” button to open the “Wireless WEP Key setup” page. When you decide to use the WEP encryption to secure your WLAN, please refer to the following setting of the WEP encryption:  64-bit WEP Encryption：64-bit WEP keys are as same as the encryption method of 40-bit WEP. You can input 10 hexadecimal digits (0~9, a~f or A~F) or 5 ACSII chars.

42 128-bit WEP Encryption：128-bit WEP keys are as same as the encryption method of 104-bit WEP. You can input 26 hexadecimal digits (0~9, a~f or A~F) or 10 ACSII chars.  The Default Tx Key field decides which of the four keys you want to use in your WLAN environment. WEP Encryption with 802.1x Setting The device supports external RADIUS Server that can secure networks against unauthorized access. If you use the WEP encryption, you can also use the RADIUS server to check the admission of the users. By this way every user must use a valid account before accessing the Wireless LAN and requires a RADIUS or other authentication server on the network. An example is shown as following. EthernetRADIUS ServerWireless StationAP You should choose WEP 64 or 128 bit encryption to fit with your network environment first. Then add user accounts and the target device to the RADIUS server. In the device , you need to specify the IP address、Password (Shared Secret) and Port number of the target RADIUS server.

43 WPA Encryption Setting WPA feature provides a high level of assurance for end-users and administrators that their data will remain private and access to their network restricted to authorized users. You can choose the WPA encryption and select the Authentication Mode. WPA Authentication Mode This device supports two WPA modes. For personal user, you can use the Pre-shared Key to enhance your security setting. This mode requires only an access point and client station that supports WPA-PSK. For Enterprise, authentication is achieved via WPA RADIUS Server. You need a RADIUS or other authentication server on the network.  Enterprise (RADIUS): When WPA Authentication mode is Enterprise (RADIUS), you have to add user accounts and the target device to the RADIUS Server. In the device , you need to specify the IP address、Password (Shared Secret) and Port number of the target RADIUS server.  Pre-Share Key: This mode requires only an access point and client station that supports WPA-PSK. The WPA-PSK settings include Key Format, Length and Value. They must be as same as each wireless client in your wireless network. When Key format is Passphrase, the key value should have 8~63 ACSII chars. When Key format is Hex, the key value should have 64 hexadecimal digits (0~9, a~f or A~F).
