A portion of a network that shares a common address component. On TCP/IP networks, subnets are

that start with 192.168.0. would typically be part of the same subnet.
SSID.

network from another. Wireless devices must use the same SSID to communicate. SSIDs are up to 32
characters long, and are case-sensitive.
TCP/IP.
The Transmission Control Protocol (TCP) and the Internet Protocol (IP) are protocols that let different
types of computers communicate with each other. The Internet is based on this suite of protocols.
TKIP.
Temporal Key Integrity Protocol, a protocol used with the WPA data encryption mode that scrambles
security keys using a hashing algorithm and adds an integrity-checking feature that ensures the keys haven't
been tampered with.
WEP.
Wired Equivalency Protocol, a security protocol defined in the original 802.11b specification that is used
to provide data encryption and user authentication.
WPA.
Wi-Fi Protected Access, a security protocol for wireless networks defined by the Wi-Fi Alliance that was
designed to improve upon the WEP security protocol through improved data encryption and user
authentication.
