In the near future, we expect most wireless ISPs will adopt standards-based technologies — specifically a standard called WiMax, described later in this chapter in the sidebar “Coming soon: WiMax.”
Broadband wireless has so many different variants that we can’t put together a simple “speed, price, availability, networkability” set of criteria for you like we did for cable, DSL, and satellite.
What we can tell you is where to go for more information and to find out what wireless ISPs are available in your area: the site of our buddy Robert Hoskins. It’s called Broadband Wireless Exchange (www.bbwexchange.com). Robert’s got the best site that we know of for all things metro wireless. The site even offers a tool to drill down to your specific town and discover all of the available broadband wireless options.
Just go to his locator at www.bbwexchange.com/wisps/ (the “wisps” stands for wireless ISPs), and you can search for wireless ISPs in your town. Happy hunting!

Boosting Performance on Your Wireless Network

“Vle -found vihere the security breach in the WLAN, vias originating. It vtas cowing in through another rogue robot-vac. This is the third one this month. Hust have gotten avtay £ron\ it's ovmer, like all the rest.”
In this part . . .
7his is where you’ll really get your money’s worth from Wireless Network Hacks & Mods For Dummies. We focus on taking your wireless network and making it better, faster, and stronger, just like the Bionic Man.
We start off with a discussion of a few of the biggest issues folks face when installing wireless networks: how to make them interoperate with their overall network. We talk about how to configure your routers and make your IP network work properly.
If you want to be able ensure that your network is doing what you want it to do, you need to be able to measure its performance. We tell you how to do that with a chapter on network monitoring.
Then we discuss how you can expand and extend your network by using antennas, signal boosters, repeaters, and more. You’ll be able to reach all of the nooks and crannies in your house and even extend beyond it.
Finally, we give you some solid advice on how to keep all of this wireless networking secure from prying eyes.
Chapter 5
Combining Wired and Wireless Networks
In This Chapter
^ Fitting wireless into your home ^ Understanding IP addresses ^ Building private and public networks ^ Extending networks around the home
ШуЯ tireless networks fit into your home’s overall network infrastructure.
▼ ▼ In some cases, a wireless network may be your only network — maybe you’re in a studio apartment with a cable modem, a wireless router, two laptops, and nothing more. But as you do more and more with your networks, you find more uses for a whole-home network that includes wired (Ethernet), wireless (Wi-Fi or Bluetooth), and alternative network technologies (like technologies that allow you to send Ethernet data packets across phone lines, electrical power lines, or even over the coaxial cable used for your cable TV system).
All of these things are possible, and even probable. In particular, we suspect that you have some “wired” Ethernet gear on your network. Centralized devices such as media servers, NAS storage boxes, and printers sometimes just make better economic sense if they’re connected with wires — you have no reason to spend extra money for wireless capabilities on devices that are going to live their entire lifespan three feet from your network’s router.
Although we are wireless enthusiasts to the bitter end, we acknowledge that wired networks are cheaper, faster, and safer than wireless. That’s why we are big proponents of building wired network infrastructure when you can, even if you plan on going wireless — if you’re building or remodeling a house, take our advice and put in CAT-5e or CAT-6 cabling to enable Ethernet in every room. Trust us: Just do it.

Part II: Boosting Performance on Your Wireless Network
Wired and alternative networks can also come in handy as a means of extending and improving your wireless network’s coverage — sometimes the best way to get coverage in that remote room on the third floor is to just install a separate access point in that room, and the easiest way to do that is to run cabling to that location.
But don’t despair if you can’t run cable to remote rooms and build a wired backbone for your network. Some handy Wi-Fi devices like repeaters and bridges leverage the airwaves to extend your network further than it’s ever gone before.
In this chapter, we talk about all of the technologies and devices that let you connect different networks together — wired to wireless or even just wireless to wireless. We will also spend some time discussing how to manage the network — how to configure routers and switches, how to ensure that IP addresses work, that devices can “talk” to each other, and even how to separate parts of your network to create “public” and “private” network segments. (This is really handy if you’re creating a hot spot, as we discuss in Chapter 12.)
