DNS Server Address (Domain Name System)
DNS allows Internet host computers to have a domain name and one or
more IP addresses. A DNS server keeps a database of host computers and
their respective domain names and IP addresses, so that when a user enters
a domain name into the Internet browser, the user is sent to the proper IP
address. The DNS server address used by the computers on your home
network is the location of the DNS server your ISP has assigned.
DSL Modem (Digital Subscriber Line) - A DSL modem uses your existing

ESSID (Extended Service Set Identifier)
You must have the same ESSID entered into the gateway and each of its

Ethernet
The most widely used LAN access method, which is defined by the IEEE
802.3 standard. Ethernet is normally a shared media LAN meaning all
devices on the network segment share total bandwidth. Ethernet networks
operate at 10Mbps using CSMA/CD to run over 10-BaseT cables.
Firewall
A firewall determines which information passes in and out of a network.
NAT can create a natural firewall by hiding a local network’s IP addresses
from the Internet. A Firewall prevents anyone outside of your network from
accessing your computer and possibly damaging or viewing your files.
