LAN - A local area network (LAN) is a group of computers and
associated devices that share a common communications line
and typically share the resources of a single processor or server
within a small geographic area (for example, within an office
building).
MAC Address - Short for Media Access Control address, a hard-
ware address that uniquely identifies each node of a network. In
IEEE 802 networks, the Data Link Control (DLC) layer of the OSI
Reference Model is divided into two sublayers: the Logical Link
Control (LLC) layer and the Media Access Control (MAC) layer.
The MAC layer interfaces directly with the network media.
Consequently, each different type of network media requires a
different MAC layer.
Ping (Packet INternet Groper) - A utility to determine whether
a specific IP address is accessible. It works by sending a packet
to the specified address and waiting for a reply. PING is used
primarily to troubleshoot Internet connections.
Preamble Type- The preamble defines the length of the CRC
block for communication between the Access Point and a roaming
Network Card. (High network traffic areas should use the shorter
preamble type.) All wireless points (nodes) on your network
should use the same preamble type.
RJ-45 - Short for Registered Jack-45, an eight-wire connector
used commonly to connect computers into local-area networks
(LAN), especially Ethernets. RJ-45 connectors look similar to the
RJ-11 connectors used for connecting telephone equipment,
only wider.
RTS Threshold- This value should remain at its default setting of
2,432. Should you encounter inconsistent data flow, only minor
modifications are recommended.
Roaming – Is the ability to move from one AP coverage area to
another without interruption in service or loss in connectivity.
