If you are new to networking and have never configured these settings before, we recommend you to leave the default settings unchanged.  1. Beacon Interval: This is a time interval between any two consecutive Beacon packets sent by an Access Point to synchronize a wireless network. Specify a valid value between 20 and 999. The default setting is 100. 2. Fragment Threshold: Specify a valid Fragment Threshold value between 255 and 2346. The default is 2346. Any wireless packet exceeding the preset value will be divided into several fragments before transmission. 3. RTS Threshold: Specify a valid value between 1 and 2347. The default is 2347. If a packet exceeds the preset value, RTS/CTS scheme will be used to reduce collisions. A smaller value is recommended if you have distant clients or interference on your network.
                                                                                          300M Wireless AP 18 4. DTIM Interval: A DTIM (Delivery Traffic Indication Message) Interval is a countdown informing clients of the next window for listening to broadcast and multicast messages. When such packets arrive in the router's buffer, the router will send DTIM (delivery traffic indication message) and DTIM interval to alert clients of the receiving packets. Specify a valid value between 1-255. The default is 1. 5. TX Power: Control TX power. Specify a valid value between 17 and 23. The default is 23. 6. Power Lockout: Once enabled, you cannot change power manually. 7. Wireless LED: You can enable or disable wireless LED.   8. Preamble: The 8 bytes of the preamble and the Start of Frame create a pattern of 64 bits. 7 bytes of the preamble are for synchronization and 1 byte is for SFD, which basically says here comes a new frame, being a "get ready" notification. There are two types of preambles: long preamble and short preamble. By default, the device transmits data using the long preamble. 5.4 Access Control Specify a list of devices to allow or disallow a connection to your wireless network via the device's MAC addresses. To deactivate this feature, select "Disable"; to activate it, select "Allow" or "Deny".  MAC Filter Mode: Select Allow or Deny from the drop-down list. 1. To permit a wireless device to connect to your wireless network, select Allow, enter its MAC address, click Add and then OK. Then only this device listed as “Allowed” will be able to connect to your wireless network; all other wireless devices will be forbidden. 2. To disallow a wireless device to connect to your wireless network, select Deny, enter its MAC address, click  Add and then OK. Then this device listed as “Denied” will be unable to connect to your wireless network. 7 SNMP The Simple Network Management Protocol (SNMP) is widely used in local area networks (LANs) for collecting information, managing, and monitoring network devices, such as servers, printers, hubs, switches, and routers. Specialized software in each SNMP capable device, known as an Agent, continuously monitors the status of the device and reports the results to the SNMP Manager software, which can then act on the report. This device supports both SNMP v1 and SNMP v2C.
                                                                                          300M Wireless AP 19  Click Enable to enable the SNMP feature. 1. Administrator Name: Input the administrator’s name. 2. Device Name: Input the name of the AP, e.g., WIRELESS AP. 3. Location: Input the AP’s location. 4. Read Community: Indicates the community read access string to permit reading this AP’s SNMP information. The default is Public. 5. Write/Read Community: Indicates the community write/read access string to permit reading and re-writing this AP’s SNMP information. The default is Private. 8 Tools 8.1 Maintenance Firmware Upgrade Firmware upgrade is released periodically to improve the functionality of your device or to add new features.
