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. For the first time configuration, please login with username: root and password: root. 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.

10Knowing the Network Application The device can act as the following roles, and it supports WDS (Wireless Distribution System) function. z Access Point z WDS mode z Bridge/Router z WISP z Client mode 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. Following are 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 other wired Ethernet (LAN) port bridges to the private WLAN. The NAT is existed between WAN and WLAN/LAN and all the wireless and wired 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 WAN port will bridge to the other 4 LAN ports. 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 both the wired Ethernet ports of the device. When setup as this mode, the wireless radio will be client mode connecting to the AP of your ISP as the WAN connection and then you can configure the WAN IP configuration to meet your WISP 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

11provides a connection to a wired LAN. Client mode This mode enables the establishment of connection with the other AP using infrastructure/Ad-hoc networking types. With bridge operation mode, you can directly connect one of the wired Ethernet port to your PC and the device becomes a wireless adapter. And with WISP operation mode, you can connect one of 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 combines up to 8 AP to a single wireless network; 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. AP + WDS This mode combines WDS plus AP modes, and it not only allows WDS connections but also the wireless clients can survey and associate 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.

Basic Data Rates Choose the ACK rate for this device in B/G mode. Beacon Interval Beacons are the packets sending by Access point to synchronize the wireless network. The beacon interval is the time interval between beacons sending by this unit in AP or AP+WDS mode. The default and recommended beacon interval is 100 milliseconds. Data Beacon Rate (DTIM) This is the Delivery Traffic Indication Map. It is used to alert the clients that multicast and broadcast packets buffered at the AP will be transmitted immediately after the transmission of this beacon frame. You can change the value from 1 to 255. The AP will check the buffered data according to this value. For example, selecting “1” means to check the buffered data at every beacon. 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. TX Power The default TX power is 100%. In case of shortening the distance and the coverage of the wireless network, input a smaller value to reduce the radio transmission power. For example, input 80 to apply 80% Tx power. Short Preamble Default: Disable. It is a performance parameter for 802.11

27b/g mode and not supported by some of very early stage of 802.11b station cards. If there is no such kind of stations associated to this AP, you can enable this function. Short Slot For a WLAN network with 802.11g/n devices, the time slot can be set short to increase the throughput. Disable this option for the backward compatibility with 802.11b device.
