If a device sends data to another station on the network and the destination MAC address is not yet 
recorded, ARP is used. An ARP request is broadcast onto the network. All stations on the network 
receive and read the request. The destination IP address for the chosen station is included as part of 
the message so that only the station with this IP address responds to the ARP request. All other...

IP Configuration by DHCP
When an IP-based local area network is installed, each computer must be configured with an 
IP address. If the computers need to access the Internet, they should also be configured with a 
gateway address and one or more DNS server addresses. As an alternative to manual 
configuration, there is a method by which each computer on the network can automatically obtain 
this...

Stateful Packet Inspection
Unlike simple Internet sharing routers, a firewall uses a process called stateful packet inspection to 
ensure secure firewall filtering to protect your network from attacks and intrusions. Since 
user-level applications such as FTP and Web browsers can create complex patterns of network 
traffic, it is necessary for the firewall to analyze groups of network connection...

Category 5 Cable Quality
Category 5 distributed cable that meets ANSI/EIA/TIA-568-A building wiring standards can be a 
maximum of 328 feet (ft.) or 100 meters (m) in length, divided as follows:
20 ft. (6 m) between the hub and the patch panel (if used)
295 ft. (90 m) from the wiring closet to the wall outlet
10 ft. (3 m) from the wall outlet to the desktop device
The patch panel and other connecting...

Note: Flat “silver satin” telephone cable may have the same RJ-45 plug. However, using telephone 
cable results in excessive collisions, causing the attached port to be partitioned or disconnected 
from the network.

The wireless router incorporates Auto UplinkTM technology (also called MDI/MDIX). Each 
LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port 
should have a normal connection (e.g. connecting to a computer) or an uplink connection (e.g. 
connecting to a router, switch, or hub). That port will then configure itself to the correct 
configuration. This feature also...

April 2006
For the initial setup of your router, you will need to connect a computer to the router. This 
computer has to be set to automatically get its TCP/IP configuration from the router via DHCP.
Note: For help with DHCP configuration, please use the Windows TCP/IP Configuration 
Tutorials on the Resource CD, or in this appendix.
Internet Configuration Requirements
Depending on how your Internet service set up your account,...
