hereafter referred to as the “device”. To use this guide, you should have experience working with the TCP/IP configuration and be familiar with the concepts and terminology of wireless local area networks. NOTE: Only those antennas that are of the same type and with lesser gain than those that are certified with this device may be used legally by the installer.
Quick Start Guides The purpose of these guides is to provide sample configurations for some of the most common applications of the DLB21XX units. Access Point (Bridged) This is how the radio is configured by default. This configuration bridges the ethernet and wireless interfaces and disables all NAT/firewall functions. The first thing you will want to do is set the Operation Mode to Bridge mode. This configures the unit to bridge the interfaces together.
The second thing you will do is configure the Wireless Basic Settings. Make sure the ‘Disable Wireless LAN Interface’ checkbox is not checked. The Mode needs to be set to ‘AP’. The SSID can also be changed at this point, if desired. NOTE: For ease of management, you may also want to change the LAN IP address to reside on the subnet your other PCs will be on. This is all you have to do for a basic bridged access point. You will need to reboot the unit for the changes to take effect.
To enable the Access Point with routing, first change the Operation Mode to ‘Router’. For ease of management, you may also want to change the LAN IP address to reside on the subnet your other PCs will be on when connected to the WLAN.
The WAN Interface will then need to be configured. In this example, the WAN interface will obtain its IP address by DHCP. In the Wireless Basic Settings the Mode needs to be set to ‘AP’, and the Disable Wireless LAN Interface checkbox needs to be unchecked. The SSID can also be changed at this point, if desired. These settings enable a basic routing access point. Access Point Client Mode This device can be configured as a wireless Ethernet adapter.
In “Basic Settings” page, change the Mode to “Client” mode. And key in the SSID of the AP you want to connect then press “Apply Changes” button to apply the change. 1 2 3 Check the status of connection in the “Status” web page The alternative way to configure is as follows: In the “Wireless Site Survey” page, select one of the SSIDs you want to connect and then press “Connect” button to establish the link.
2 1 3 If the link is established successfully it will show the message “Connect successfully”. Then press “OK”. Then you can check the linking information in “Status” page. NOTE: If the available network requires authentication and data encryption, you need to setup the authentication and encryption before step1 and all the settings must be as same as the Access Point or Station. For more information about the detail authentication and data encryption settings, please refer the security section.
setting is “Auto”, not every Access Points can support “Auto” mode. If the authentication type on the Access Point is known by the user, we suggest setting the authentication type the same as the Access Point. Data Encryption In client mode, the device supports WEP and WPA Personal/Enterprise except WPA2 mixed mode data encryption. For more information about the detail data encryption settings, please refer the security section.
The alternative way to configure is as follows: In the “Wireless Site Survey” page, select one of the SSIDs you want to connect and then press “Connect” button to establish the link. 2 1 3 If the link is established successfully it will show the message “Connect successfully”. Then press “OK”. Then you can check the linking information in “Status” page.
encryption before step1 and all the settings must be as same as the Access Point or Station. For more information about the detail authentication and data encryption settings, please refer the security section. Authentication Type In client mode, the device also supports two Authentication Types “Open system” and “Shared Key”. Although the default setting is “Auto”, not every Access Points can support “Auto” mode.
Under TCP/IP > WAN Interface, the WAN connection needs to be set up. This specifies how the AP client will communicate with the network behind the remote access point. In this case DHCP client is used, and the WAN IP address is obtained from the remote access point. The next step is configuring the TCP/IP > LAN interface. This defines what happens to any connections made through the ethernet port. In this case DHCP server is enabled, so any connections made will be assigned an IP in the range of 192.168.2.
First under Operation Mode, make sure both units are in ‘Bridge’ mode. Then under Wireless > Basic Settings, set the wireless radio on both units to ‘WDS’ mode. Radio A and Radio B both need to use the same Channel Number in order for WDS to connect; in this case, the Channel Number is 1.
Since the two units will be bridged together, the LAN IP addresses will need to be different or one of the units will not be accessible by IP address. The next step is to add the MAC address of the wireless interface in the WDS bridge in Radio B in the WDS section in Radio A. NOTE: The MAC address of the wireless interface in Radio B can be found on the Status page under Management in the configuration section of the Wireless interface you are using for the WDS bridge. In this case it is 00:05:9e:84:00:12.
In Wireless > WDS Settings, make sure “Enable WDS” is checked. Enter the MAC address from Radio B into the WDS Settings for Radio A (no colons or spaces). Click “Apply Changes” The MAC address will then show up in the Current WDS AP List. NOTE: This will need to be done on both radios. The WDS should then be established. NOTE: Be careful not to create a network loop without having STP (Spanning Tree Protocol) enabled on both units.
Enable Universal Repeater Mode and then select an SSID in the Table that you want. Then click the Apply Changes button. (Click the Refresh button to refresh the table.) NOTE: Universal Repeater Mode is only available under AP, WDS and AP+WDS mode. Enter specific SSID in the Extended SSID field and then click the Apply Changes button.
Wireless Setup Initial Configuration 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).
Router In this operation mode, the wired Ethernet (WAN) port is used to connect with an ADSL/Cable modem and the wireless NIC is used for your private WLAN. The NAT is enabled between the 2 NICs, and all the wireless clients share the same public IP address through the WAN port to the ISP. The default IP configuration for the 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.
AP Client This mode provides the capability to connect with another 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 the hub/switch can share the same public IP address from your ISP.
Wireless Configuration Basic Settings Disable Wireless LAN Interface Disable the wireless interface of device Band The device supports 2.4GHz(B), 2.4GHz(G) and 2.4GHz(B+G) mixed modes. Mode The radio of the device supports different modes as follows: AP The radio of the device acts as an Access Point to serves all wireless clients to join a wireless local network. Client Support Infrastructure and Ad-hoc network types to act as a wireless adapter.
Network Type Infrastructure This type requires the presence of 802.11b/g Access Point. All communication is done via the Access Point. 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. In client mode, the device can not support the Router mode functions including Firewall and WAN settings.

Advanced Settings These settings are only for more technically advanced users who have sufficient knowledge about wireless LANs. 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. NOTE: Any unreasonable value change from the default settings will reduce the throughput of the device. Authentication Type The device supports two Authentication Types “Open system” and “Shared Key”.
ACK Timing This is the amount of time that a station will wait for the ACK response after sending a wireless frame to a remote station. This is roughly transmission time (round-trip) + processing time on the remote station and can vary depending on environment. Generally a trial and error approach is best for finding optimum timing and should only be changed on longer wireless links.
Transmit Power The device supports four transmission output power levels 250, 200, 150 and 100mW for CCK (802.11b) mode and two transmission output power levels 100 and 50mW for OFDM (802.11g) mode. You can adjust the power level to change the coverage of the device. Every wireless station located within the coverage of the device also needs to have the high power radio. Otherwise the wireless station can only survey the device and cannot establish a connection with device.
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. Encryption Wired Equivalent Privacy (WEP) is implemented in this device to prevent unauthorized access to your wireless network.
• 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 determines which of the four keys you want to use in your WLAN environment. WEP Encryption with 802.1x Setting The device supports an 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.
WPA Authentication Mode The WPA feature provides a high level of assurance for end-users and administrators that their data will remain private and that access to their network is restricted to authorized users. You can choose the WPA encryption and select the Authentication Mode. This device supports two WPA modes: Enterprise (RADIUS) In this mode authentication is achieved via a WPA RADIUS Server. You need a RADIUS or other authentication server on the network.
• You don’t need to add all MAC address of devices existing in your network to the WDS AP List. The WDS AP List only needs to specify the MAC address of devices you need to directly connect to. • The bandwidth of the device is limited. Bandwidth will be shared between bridging devices. WDS Network Topology In this section, we will demonstrate the WDS network topologies and WDS AP List configuration. You can setup four kinds of network topologies: bus, star, ring and mesh.

Firewall Configuration Configuring LAN to WAN Firewall The device supports three kinds of filter Port Filtering, IP Filtering and MAC Filtering. All the entries in current filter table are used to restrict certain types of packets from your local network through the device. Use of such filters can be helpful in securing or restricting your local network. Port Filtering When you enable the Port Filtering function, you can specify a single port or port ranges in the current filter table.
WAN. Configuring Port Forwarding (Virtual Server) This function allows you to automatically redirect common network services to a specific machine behind the NAT firewall. These settings 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 device's NAT firewall. The most often used port numbers are shown in the following table.
Configuring 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 Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (email) servers and DNS servers. All inbound packets will be redirected to the computer you set. It also is useful if you run some applications (e.g. Internet games) that use uncertain incoming ports. 49 Enable DMZ Enables the DMZ.
Configuring VPN 50
Management Configuration Quality of Service (QoS) QoS allows you to specify some rules, to ensure the quality of service in your network, such as Bandwidth Priority to allocate bandwidth. This function can be helpful in shaping and queuing traffic from LAN (WLAN) to WAN or LAN to WLAN, but not WLAN to WLAN. Enable the QoS and then fill in the Bandwidth Ratio (H/M/L). The device has three Bandwidth Priorities High, Medium and Low.
QoS Enabled Bandwidth Borrowed Max Throughput Bandwidth Ratio (H/M/L) Apply Changes Select this check box to enable quality of service. Select this check box to allow a rule to borrow unused bandwidth. Bandwidth borrowing is decided by priority of the rules. Higher priority will get the remaining bandwidth first. Enter the value of max throughput in kbps that you want to allocate for one rule. The value should between 1200 kbps and 24000 kbps. You can specify the ratio of priority in these fields.
the rules. This table can handle 50 rules at most. An example for usage For example, there are three users in your network. User A wants to browse the websites to retrieve information. User B wants to use FTP connection to download a large file. User C wants to use software phone to connect with customer. Since VoIP traffic is sensitive to variations in delay (jitter), you can set High priority for User C. However, because the FTP transmission may take a long time, you can set Low priority for User B.
NOTE: Only device on Client mode or WISP mode this functionality can take effective.
