Type this RADIO’s address http://192.168.1.1 in the Location (for IE) or Address field and press Enter. 2.  Enter the system name (the default setting is “admin”) and password (the default setting is “password”). 3.  Click on the “Login now” button. 4.  The main page will appear.   After you have logged-in the main page, the About, Basic Setup, Wireless Setup, Status, Management buttons will be shown. The main menu provides links to the whole sections of the web configuration interface.
 -10-About The About screen describes the product information briefly. The RADIO information includes Wireless Bridge Name, MAC Address, and Firmware Version.    Basic Setup
 -11-The Wireless Bridge Name is used to give a name to your bridge. This will enable you to manage your Wireless Bridge more easily if you have multiple Wireless Bridges on your network. Ethernet Data Rate: The basic transfer rates should be set depending on the speed of your Ethernet network. Select the desired rate from the drop-down menu and choose “Automatic” to adapt 10Mbps or 100Mbps Base-T by automatic detection. Spanning Tree Protocol : This function provides optimization of network traffic for multiple wireless bridges. You may Enable or Disable the Spanning Tree Protocol used in the wireless bridge.  VLAN(802.1Q) : VLANs can enhance performance by conserving bandwidth, and improve security by limiting traffic to specific domains. You may select the Enable will link the VLAN functionality on the Base Station.    Management VLAN ID : This allows 802.1Q VLAN devices to management the WEB GUI   of the    RADIO. The default value is “0” which allows all untagging (Non VLAN) devices to access the  RADIO.   IP Address As a Bridge mode, you can assign a proper IP address to your wireless bridge manually by selecting  Manual. If you would like the wireless bridge to obtain the IP address from the DHCP server on your network automatically, select DHCP. IP Address: Type the IP address of your bridge. (Default: 192.168.1.1). IP Subnet Mask: The Bridge’s Subnet Mask must be the same as your Ethernet network. We recommended that you do NOT change the value. (Default: 255.255.255.0). Default Gateway: The Bridge will use this value for default Gateway. Primary DNS Server: The Bridge will use this value for primary Domain Name Server. Secondary DNS Server: The Bridge will use this value for secondary Domain Name Server. Time While you connect the Bridge to Internet, the Bridge could automatically synchronize the current time of the bridge with the Time Server that you have set. Time Server: the central time of the Time Server. Time Server Port: the port of the Time Server. Time Zone: You may select the appropriate local time zone for your Bridge from a list of all available time zones. Default: GMT. Note: If you complete the settings, please click on “Apply” for changes to take effect.
 -12-3-2 Wireless Setup Radio Settings:     Operating Mode: There are three different wireless modes to operate, Base Station, CPE, and Peer-to-Peer. The default is “Base Station”. Basically, the Multi-Client mode and LAN-to-LAN mode all are used to support multiple devices to access internet through CPEs. But Multi-Client mode only supports IP packet, and LAN-to-LAN supports any Ethernet protocol. If the Base Station supports LAN-to-LAN capability(this firmware embedded), then the CPEs which connect to that Base Station could be configured to Multi-Client mode or LAN-to-LAN mode. If the Base Station doesn't support LAN-to-LAN capability(old firmware embedded), then the CPEs which connect to that Base Station should be configured to Multi-Client mode. Base Station ID: Edit VBS/VLAN Settings. Modulation: For this model, the modulation is OFDM. Channel / Frequency: Select the appropriate channel/Frequency from the list provided to correspond with your network settings. Data Rate: The basic transfer rates should be set depending on the speed of your wireless network. To specify rate of data transmission, select the desired rate from the drop-down menu and choose “Best” to adapt the rate to the best available. Output Power: Set the transmit signal strength of RADIO. The options are full, half, quarter, eighth and min. Decrease the transmit power if necessary. The best performance for max. throughput test is preset at the “full” setting. It should be selected again after being reset.
 -13-Bandwidth: Set the transmit signal bandwidth of RADIO. The default is “20MHz”. VQoS/TDM:  Enable VQoS/TDM to allow Base Station to use the technology of Time Division Multiplexing by assigning each data stream for CPE a equal time slot per cycle. The default setting is “Disable”. Antenna: For this model, the default is “Fixed on Primary” Regatta Mode: Choose “Enable” for anti-interference, it may be make better the performance of throughput. The default setting is “Disable”.  Advanced Parameters These parameters can be changed if needed, but the default advanced setting usually work well. It is recommended that you keep all these values in factory default. CPE Download Speed: This function provides flow control with a multiple of 64kbps for CPE . The setting range is 1-1687. RTS Threshold: RTS Threshold is a mechanism implemented to prevent the “Hidden Node” problem. If you have more collisions, it is recommended to enable RTS. If you have fewer collisions, it is not necessary to enable RTS. Forcing the wireless bridge to implement the RTS/CTS handshake will significantly increase the overhead and reduce throughput. If the size of the packet transmitted is larger than the value you set, the RTS should be enabled. The setting range is 0-2346. Fragmentation Length: Fragmentation mechanism is used for improving the efficiency when there is high traffic within the wireless network. If you transmit large files in a wireless network, you can enable the Fragmentation Threshold and specify the packet size. This specifies the maximum size a data packet will be before splitting and creating a new packet. The setting range is 256-2346. For example: If you set value as 256, it means the packet will be fragmented into “256” bytes while transmitting.   Bacon Interval: This value indicates the frequency interval of the beacon.    A beacon is a packet broadcast by the Base Station to keep the network synchronized. A beacon includes the wireless network service area, the Base Station address, the Broadcast destination addresses, a time stamp, Delivery Traffic Indicator Maps, and the Traffic Indicator Message (TIM). The setting range is 4-1000. Space In Meter: This space in meter is used for extending ACK time-out destination. The setting range is 0-100000. It would be better set this parameter per the actual distance. For PTMP connection, the parameter of the Center point or Base Station would be the distance between the Center and the farthest remote site. TDM Time Slice Value: The setting range is 2-32 ms.   The minimum value is 20 ms for Channel bandwidth 5MHz, 10ms for Channel bandwidth 10MHz and 5 ms for Channel bandwidth 20MHz. SoftwareRetry: The setting range is 0-15 ms. HardwareRetry: The setting range is 1-15 ms.
 -14-Site Survey   This Site Survey shows only when RADIO is CPE mode. By clicking the “Refresh” button, the Site Survey will reload and display available Base Stations around the working environment. It will display the information of each Base Station which are index, Base Station ID, MAC address, RSSI, Channel, Connect status and Encryption. To connect one of displayed Base Stations, just select the Base Station you desire and then click the “Select” button to make the connection. Click the “Back” button if you want to return to the “Radio Setting”.   Peer-to-Peer Links
 -15-The feature lets you extend the range of your network without having to use cables to link your RADIO, meaning that you can link bridge wirelessly. There are two modes in which RADIO can be configured. Select the desired mode for your environment.  VBS / VLAN Settings This section will test the VLAN functionality on the Base Station. It is expected that CPEs in the same VLAN and the same BSS can communicate with each other while CPEs in the different VLANs or in the same VLAN but the different BSSs can’t. It is also expected that Base Station can only be managed through the management VLAN.  Security Profiles:  For Base Station, there are up to 8 profiles to configure and work simultaneously. For CPE mode, you need select the CPE_Profile for encryption settings. For Peer-to-peer mode, you need select the PTP_Profile for encryption settings.  VLAN(802.1Q) Setup: Setup VLAN ID for the specified profile. Packets that are tagged (are carrying the 802.1Q VLAN ID information) can be transmitted from one 802.1Q compliant network device to another.
 -16-  Example 1 :    1. Enable Base Station VLAN function, set the BSS1 SSID as SSID1 and VLAN ID as 1,     BSS2 SSID as SSID2 and VLAN ID as 2;     2.

Verify that CPE1, CPE2, CPE3 and CPE4 all cannot communicate with each other.            Profile Definition: Security Profile Name is used give a name to your system. Wireless Network Name (SSID): The Base Station ID is a unique ID used by Base Station and CPEs to identify a wireless network. CPEs associating to any Base Station must have the same ID. The default ID is “Wireless”. To change the ID, type in the ID you like to use. It is case sensitive and must not exceed 32 characters. Broadcast Wireless Network Name (SSID): For security concern, you can choose not to broadcast your network’s ID. To turn off the broadcast of the ID, click “No” check box next to “Broadcast Base Station ID”. And your Base Station will refuse the connection requests from whose are not aware the Network ID. But certainly the Base Station can be easily connected well when you realize the Network ID. The default setting is “Yes”.
 -20- Network Authentication Choose the Network Authentication Type. Open System: Requires NO authentication, since it allows any device to join a network without performing any security check. The Authentication Type default is set to “Open System”. We recommend that you use the default setting. Shared Key: Requires that the CPE and the Base Station use the same WEP key to authenticate. This basically means that WEP must be enabled and configured on both the Base Station and the CPE with a same key. All points on your network must use the same authentication type. WPA-PSK: If selected, you must use TKIP encryption, and enter the WPA Pre-Shared Key. WPA2-PSK: If selected, you must use AES encryption, and enter the WPA Pre-Shared Key.  WPA Pre-Shared Key: When selecting the WAP-PSK or WPA2-PSK, you may enter 8-63 characters ranging from “a-z”, “A-Z”, and “0-9”. Data Encryption Select the desired option. If enabled (64 bit WEP, 128 bit WEP, 152 bit WEP), the keys must have the same encryption strength and must be the same with the keys that other wireless devices use. The TKIP option is automatically activated when “WPA-PSK” is enabled. And the AES option is automatically activated when “WPA2-PSK” is enabled.  64 bits WEP : Enter 10 hexadecimal digits (between 0-9, a-f and A-F). 128 bits WEP: Enter 26 hexadecimal digits (between 0-9, a-f and A-F). 152 bits WEP: Enter 32 hexadecimal digits (between 0-9, a-f and A-F). Note: The WEP key must be set up exactly the same on the RADIOs. If you set “0011223344” for the Base Station or Wireless Bridge, the same WEP key “0011223344” must be assigned to other CPEs or Wireless Bridges.    Note: If you complete the settings, please click on “Apply” for changes to take effect.  Wireless Client Security Separator Enable this function to let associated CPEs be able to separate from each other when security is required. The default setting is Disable. Note: If you complete the settings, please click on “Apply” for changes to take effect.
 -21- Access Control Authentication by username and password is only part of the story. Frequently you want to let people in based on something other than who they are. Something such as where they are coming from. Restricting access based on something other than the identity of the user is generally referred to as Access Control.    You can restrict access to only trusted CPEs so that unknown CPEs cannot wirelessly connect to the RADIO by turning Access Control on. By entering MAC Address of new stations, you can manually add the stations to allow them to be connected to the RADIO.
 -22-3-3 Status Connections   For Base Station mode, the connections page displays the association condition of Base Station includes CPE ID, MAC Address, IP Address, Moderation Data Rate, RSSI(dBm) and Status.
