802.11g 4-Port Wireless LAN Broadband Router
Shared Key
It’s when both the sender and recipient share a secret key. Both units use this key for an extended length of time, sometimes indefinitely. Any eavesdropper that discovers the key may decipher all packets until the key is changed.
Signal Strength
The signal level indicates the strength of the signal as received at the wireless network interface.
SSID (Service Set Identifier)
It’s the unique name shared among all points in a wireless network. The SSID must be identical for all points in the network. It is case sensitive and must not exceed 32 characters.
TCP/IP
Transmission Control Protocol (TCP) with Internet Protocol (IP). The main internetworking protocol used in the Internet.
UDP (User Datagram Protocol)
UDP provides a procedure for application programs to send messages to other programs with a minimum of protocol mechanism. The protocol is transaction oriented, and delivery and duplicate protection is not guaranteed. Applications requiring ordered reliable delivery of streams of data should use the TCP.
What is Router?
A router is a device that forwards data packets from a source to a destination. Routers forward data packets using IP addresses and not a MAC address. A router will forward data from the Internet to a particular computer on your LAN. A router also determines the best route that data packets should follow to ensure that the data packets are delivered properly.
WEP (Wired Equivalent Privacy)
A data privacy mechanism based on a 40 bit shared key algorithm, as described in the IEEE 802 .11 standard. The optional cryptographic confidentiality algorithm specified by IEEE 802.11 used to provide data confidentiality that is subjectively equivalent to the confidentiality of a wired LAN medium that does not employ cryptographic techniques to enhance privacy.
WPA (Wi-Fi Protected Access)
