uses the same IP address every time it reboots and logs on to the 

network, unless it is manually changed. 

Temporal Key Integrity Protocol (TKIP)

The Temporal Key Integrity Protocol, pronounced tee-kip, is part of the 

IEEE 802.11i encryption standard for wireless LANs. TKIP is the next 

generation of WEP, the Wired Equivalency Protocol, which is used to 

secure 802.11 wireless LANs. TKIP provides per-packet key mixing, a 

message integrity check and a re-keying mechanism, thus fixing the 

flaws of WEP. 

Transmission Control Protocol / Internet Protocol (TCP/IP)

TCP/IP is the protocol suite developed by the Advanced Research 

Projects Agency (ARPA). It is widely used in corporate Internet works, 

because of its superior design for WANs. TCP governs how packet is 

sequenced for transmission the network. The term “TCP/IP” is often 

used generically to refer to the entire suite of related protocols. 

Transmit / Receive

The wireless throughput in Bytes per second averaged over two seconds. 

Wi-Fi Alliance

The Wi-Fi Alliance is a nonprofit international association formed in 1999 

to certify interoperability of wireless Local Area Network products based 

on IEEE 802.11 specification. The goal of the Wi-Fi Alliance’s members is 

to enhance the user experience through product interoperability. The 

organization is formerly known as WECA. 

Wi-Fi Protected Access (WPA)

The Wi-Fi Alliance put together WPA as a data encryption method for 

802.11 wireless LANs. WPA is an industry-supported, pre-standard version 

of 802.11i utilizing the Temporal Key Integrity Protocol (TKIP), 

which fixes the problems of WEP, including using dynamic keys. 

Wide Area Network (WAN)

A WAN consists of multiple LANs that are tied together via telephone 

services and / or fiber optic cabling. WANs may span a city, a state, a 

country, or even the world. 

Wired Equivalent Privacy (WEP)

Now widely recognized as flawed, WEP was a data encryption method 

used to protect the transmission between 802.11 wireless clients and 

APs. However, it used the same key among all communicating devices. 

WEP’s problems are well-known, including an insufficient key length and 

no automated method for distributing the keys. WEP can be easily
