How To Deal With Wireless Encryption Security Threats
Because nobody wants to compromise the integrity of their network by having some hacker "borrow" your bandwidth or gain access and start snooping around you need to lock down your network. Fortunately, encryption is built into wireless technology; it's simply a matter knowing how to turn it on.

What is a Wireless Network?
When the term
‘wireless networkÙ is used today, it usually refers to a wireless local area network (WLAN). A WLAN connects computers together through radio technology using standard network rules or protocols, but without the use of cabling to connect the computers together.A WLAN can be installed as the sole network in a school or building. However, it can also be used to extend an existing wired network to areas where wiring would be too difficult or too expensive to implement, or to areas located away from the main network or building. The most obvious difference between wireless and wired networks, therefore, is that the latter uses some form of cable to connect computers together. A wireless network does not need cable to form a physical connection between computers. Wireless networks can be configured to provide the same network functionality as wired networks, ranging from simple peer-to-peer configurations to large-scale infrastructures accommodating hundreds of users.
Wireless Home Networking Basics
These days it seems everyone is having a wireless computer network in their home. So you decide to go for that, and you buy a device your friends suggested at the local store. You look at the box. This gizmo is a wireless access point and broadband router whatever that means. You wonder: did I buy the right thing? Is this what I need? How hard is it going to be to set this thing up?
Do not worry. You made an excellent choice. With this device you can:
- Build a home network, connecting your desktop and laptop computers together, without running any new wires in your home.
- Share files, printers, and applications across all your computers. For instance, you can sit on the deck using your untethered laptop, and print the final chapter of your new novel to the printer in the upstairs office.
- Share a broadband Internet connection among the multiple computers in your home. Everyone enjoys a high-speed connection, no one waits for modems to connect, and the phone line is never busy while Junior downloads MP3 files.
ATM Signaling and Addressing - Part Two
Addressing on the ATM Switch Router
The ATM address is used by the ATM switch router for signaling and management functions, and by protocols such as LAN emulation and PNNI. The ATM switch router ships with a preconfigured default address which allows it to function in a plug-and-play manner. You can change the default address if you need to; the main reasons for doing so are listed in the section "Manually Configured ATM Addresses" section on page 2-11. If you do not foresee needing to reconfigure the ATM address, then the details of the following sections might not concern you.
ATM Signaling and Addressing - Part One
Because ATM is a connection-oriented service, specific signaling protocols and addressing structures, as well as protocols to route ATM connection requests across the ATM network, are needed. The following sections describe the role of signaling and addressing in ATM networking.
