PPPoE - Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of secure data
transmission originally created for dial-up connections. PPPoE is for Ethernet connections.
Roaming - A function that allows your to move through a particular domain without losing
network connectivity.
Static IP - If your Service Provider has assigned a fixed IP address; enter the assigned IP
address, subnet mask and the gateway address provided by your service provider.
Subnet Mask - A subnet mask, which may be a part of the TCP/IP information provided by your
ISP, is a set of four numbers configured like an IP address. It is used to create IP address
numbers used only within a particular network (as opposed to valid IP address numbers
recognized by the Internet.
TKIP - (Temporal Key Integrity Protocol) The TKIP process begins with a 128-bit "temporal key"
which is shared among clients and access points. Then it combines the temporal key with the
client's MAC address and adds a 16-octet initialization vector to create the key that will encrypt
the data. This procedure ensures that each station uses different key streams to encrypt the
data.
TCP/IP - Transmission Control Protocol/Internet Protocol. This is the standard protocol for data
transmission over the Internet.
TCP - Transmission Control Protocol - TCP and UDP (User Datagram Protocol) are the two
transport protocols in TCP/IP. TCP ensures that a message is sent accurately and in its entirety.
However, for real-time voice and video, there is really no time or reason to correct errors, and
UDP is used instead.
UDP - User Datagram Protocol - A protocol within the TCP/IP protocol suite that is used in place
of TCP when a reliable delivery is not required. For example, UDP is used for real-time audio and
video traffic where lost packets are simply ignored, because there is no time to retransmit. If
UDP is used and a reliable delivery is required, packet sequence checking and error notification
must be written into the applications.
