300M Wireless AP

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.
