Router
An IP sharing router is a device that allows multiple PCs to share one single
broadband connection using NAT technology. A wireless router is a device that
combines the functions of wireless Access Point and the IP sharing router.
RSSI
Receiver Sensitivity Index. RSSI is a value to show the Receiver Sensitivity of the
remote wireless device. In general, remote APs with stronger signal will display
higher RSSI values. For RSSI value, the smaller the absolute value is, the stronger
the signal. For example, “-50db” has stronger signal than “-80dB”. For outdoor
connection, signal stronger than -60dB is considered as a good connection.
RTS
Request To Send. A packet sent when a computer has data to transmit. The
computer will wait for a CTS (Clear To Send) message before sending data.
RTS Threshold
RTS (Request to Send). The RTS/CTS(clear to send) packet will be send before a
frame if the packet frame is larger than this value. Lower this value can improve the
performance if there are many clients in your network. You can try 1500, 1000 or
500 when there are many clients in your AP’s network.
SNMP (Simple Network Management Protocol)
A set of protocols for managing complex networks. The SNMP network contains 3
key elements: managed devices, agents, and network-management systems
(NMSs). Managed devices are network devices that content SNMP agents. SNMP
agents are programs that reside SNMP capable device's firmware to provide SNMP
configuration service. The NMS typically is a PC based software such as HP
Openview that can view and manage SNMP network device remotely.
