1. In the system tray in the lower-right corner of your screen, right-click your wireless network adapter’s icon.
2. Select View Available Wireless Networks.
A window like the one shown in Figure 9-2 appears.
3. Search through the list of available networks until you find the network to which you would like to connect.
Note that security-enabled networks (those using WPA or WEP, and which require a password) are identified by a lock icon and the words
Security-Enabled Wireless Network.
4. To select the network you want to connect to, click it to select it, and then click Connect.
Your computer connects to the hot spot.
5. Open your Web browser and try to load a Web site.
It doesn’t matter what site you load — you can load our site www.

Figure 9-2:
Finding a hot spot in Windows XP.
If the hot spot is free, you should get onto the Web site right away — if it’s a hot spot that requires you to log in, you’ll probably see the captive portal site instead. If you get the captive portal, just fill out the required information and log yourself in!
Using the Boingo client
Boingo customers can use the company’s software client — the program that anyone can download at www.boingo.com — to connect to any hot spot. You don’t have to connect to a Boingo hot spot with this client — anyone can download it and use it to help them find and connect to hot spots.
You can also log into many Boingo hot spots just by using a Web browser and going to the captive portal site. The big advantage of using the Boingo client is that the client has a built-in VPN software system that encrypts all of the data you send out over the wireless network. No one sitting nearby your in the airport can surreptitiously “sniff” your data packets and read your email, steal your files, or intercept your downloads of that American Idol recap on TWOP (www.televisionwithoutpity.com).
On the Mac
Like Windows XP, the Mac OS X operating system is designed for easy connections to wireless networks. The steps for connecting to a hot spot are similarly short and sweet:

Getting onto a hot spot with Mac OS X.
Figure 9-4:
Entering an encryption key.
1. In the Dock, click and hold on the Applications folder and select Internet Connect.
2. In the Internet Connect window that opens (Figure 9-3), click on the AirPort icon.
3. In the Internet Connect window, use the pull-down menu to select the hot spot network to which you would like to connect.
4. If the network requires an encryption key, use the pull-down menu to select the key type and then type the key itself in the text box, as shown in Figure 9-4.
Boingo also has a client for the Mac OS — it can be used with Mac OS 10.2.8 or above. It works really well, but it doesn’t have all of the security features found in the Windows client (although the folks we know at Boingo tell us that the Mac client will be equal to the Windows client in this regard by the end of 2005). It’s already a prettier- and more elegant-looking piece of software because Apple has allowed Boingo to very tightly integrate it with the Airport software and the Safari Web browser.

166 Part III: Wireless on the Go
Help, I Need Wireless Access in Paris!
Searching for hot spots on the Web pages of any one hot spot network — be it a free network, a metro or community network, or a pay network — always limits you to a subset of the total number of hot spots available for public use. After all, hot spot company A isn’t going to tell you about hot spot company B’s network unless they are working together as partners.
So if you want to really find all of the access points available to you, you need to cast a wide net.
One way to do this is to simply use some software on your computer to thoroughly search the “airwaves” around you looking for access points. The NetStumbler software we discuss in Chapter 6, for example, does a bloodhound-like job of sniffing out APs nearby.
You don’t need NetStumbler to do this. The Wireless Zero Config software in Windows XP and the AirPort software on Mac OS X both do a pretty good job of finding any available access points — they just don’t give you quite as much detailed information as NetStumbler does.
