Configuring Wireless Security in Windows XP
This section describes how to configure basic wireless security on your Wireless Local Area
Network (WLAN) when using Windows XP.
What You Will Need Before You Begin
You need to verify your computer meets the minimum system requirements and identify the
wireless network configuration settings of the WLAN where you will connect before you can
configure your wireless pc card and connect.
Observe Location and Range Guidelines
Computers can connect over 802.11 wireless networks indoors at a range which vary significantly
based on the physical location of the computer with the CG814WG Wireless Cable Modem
Gateway. For best results, avoid potential sources of interference, such as:
• Large metal surfaces
•Microwaves
• 2.4 GHz Cordless phones
In general, 802.11 wireless devices can communicate through walls. However, if the walls are
constructed with concrete, or have metal, or metal mesh, the 802.11 effective range will decrease if
such materials are between the devices.
Note: Indoors, computers can easily connect to 802.11 wireless networks at distances of
several hundred feet. Because walls do not always block wireless signals, others outside
your immediate area could access your network. It is important to take appropriate steps
to secure your network from unauthorized access. The CG814WG provides highly
effective security features which are covered in the Comcast user manual. Deploy the
security features appropriate to your needs.
