10.5 Connecting to the Internet



If you enjoy a full-time Internet connection like a cable modem or DSL, you're constantly connected to the Internet. Skip to the next chapter.


If you have a dial-up modem, however, you should now have a connection icon in your Network Connections window.


10.5.1 Manual Connections



Double-click the connection's icon in the Network Connections window (Figure 10-3). The Connect To dialog box appears, as shown at left in that figure. Just press Enter, or click Dial, to go online.


But that's just the beginning. If you crave variety, here are a few other ways of opening the connection:



UP TO SPEED


IP Addresses and You



Every computer connected to the Internet, even temporarily, has its own exclusive IP address (IP stands for Internet Protocol). When you set up your own Internet account, as described on these pages, you'll be asked to type in this string of numbers. As you'll see, an IP address always consists of four numbers separated by periods.


Some PCs with high-speed Internet connections (cable modem, DSL) have a permanent, unchanging address called a fixed or static IP address. Other computers get assigned a new address each time they connect (a dynamic IP address). That's always the case, for example, when you connect via a dial-up modem. (If you can't figure out whether your machine has a static or fixed address, ask your Internet service provider.)


If nothing else, dynamic addresses are more convenient in some ways, since you don't have to type numbers into the Internet Protocol (TCP/IP) Properties dialog box shown in Figure 10-4.




Right-click your connection icon, and then choose Connect from the shortcut menu.



If you've added the "Connect to" submenu to your Start menu, as described in Section 2.16, just choose the name of the connection you want.



Create a desktop shortcut for your connection icon (the icon in the Network Connections window) by right-dragging it out of the window and onto the desktop. When you release the mouse button, choose Create Shortcut(s) Here from the shortcut menu. Now just double-click the shortcut whenever you feel the urge to surf.



Drag your connection icon shortcut onto the Quick Launch toolbar (Section 3.4), so that you can now get to the Internet with just one click.



10.5.2 The Notification Area Icon



While you're connected to your ISP, Windows XP puts an icon in the notification area (Figure 10-3). From the shortcut menu, choose Properties. Bottom: At the bottom of the General tab, you'll see the key feature, "Show icon in notification area when connected." Turn on this option, and then click OK.



GEM IN THE ROUGH


Faster Access to Connection Icons



In the following pages, you'll quite frequently work your way to the Network Connections window and the connection icons inside it. With just a little Start-menu surgery, however, you can directly access this folder, or the connection icons inside it, without burrowing through the Control Panel window first.



To do so, right-click the Start button. From the shortcut menu, choose Properties. Click the Customize button, and then click the Advanced tab.


Finally, scroll down until you see Network Connections. Here you have a couple of useful options. "Display as Connect to menu" adds a submenudirectly to your Start menulisting the various connections available. If you're a laptop owner, for example, and you've established connection icons for several different cities, this submenu makes it extremely easy to get online using the correct local phone number.


"Link to Network Connections Folder," meanwhile, adds a command to the right side of the Start menu called Network Connections. It opens the Network Connections window, once again saving you the intermediate step of opening Control Panel first.


When you're finished, click OK twice. Use the new spare time you've just won yourself to take up hang gliding or learn French.



10.5.3 Automatic Dialing



It's important to understand that when your PC dials, it simply opens up a connection to the Internet. But aside from tying up the phone line, your PC doesn't actually do anything until you then launch an Internet program, such as an email program or a Web browser. By itself, making your PC dial the Internet is no more useful than dialing a phone number and then not saying anything.


Therefore, using the Internet is generally a two-step procedure: First, open the connection; second, open a program.


Fortunately, Windows offers a method of combining these two steps. You can make the dialing/connecting process begin automatically whenever you launch an Internet program. This way, you're saved the trouble of fussing with the connection icon every time you want to go online.


To turn on this option, just open your Web browser and try to Web surf. When the PC discovers that it's not, in fact, online, it will display the Dial-up Connection dialog box at left in Figure 10-6. Turn on the "Connect automatically" checkbox, and then click Connect.


Figure 10-6. Left:

"Connect
automatically" makes your PC dial whenever any of your programs tries
to go online. Right: If you can't seem to get online despite taking
this step, open the Internet Options program in the Control Panel
(Section 9.7, page 265). Click the Connections tab. Make sure that "Never dial a connection" isn't selected; choose one of the other options. (That's an option for people who like to establish the Internet connection manually before opening an Internet program like a Web browser.)


From now on, whenever you use a feature that requires an Internet connection, your PC dials automatically. (Examples: specifying a Web address in a window's Address bar, clicking the Send and Receive button in your email program, clicking a link in the Windows Help system, and so on.)


10.5.4 Disconnecting



The trouble with the standard dial-up Internet connection is that, unless you intervene, it will never hang up. It will continue to tie up your phone line until the other family members hunt it down, hours later, furious and brandishing wire cutters.


Therefore, it's worth taking a moment to configure your system so that it won't stay online forever.


10.5.4.1 Disconnecting manually



When you're finished using the Internet, end the phone call by performing one of the following steps:



Right-click the little connection icon on your taskbar. Choose Disconnect from the shortcut menu (Figure 10-7, top).


Figure 10-7. Top: The quickest way to hang up is to use the notification-area icon. Right-click it and choose Disconnect from the shortcut menu that appears. Bottom: You can also double-click the icon to view statistics on your session so far, and to produce a Disconnect button for hanging up.



Double-click the little connection icon on the taskbar. Click the Disconnect button in the Status dialog box that appears (Figure 10-7, bottom), or press Alt+D.



Right-click the connection icon in your Network Connections window. Choose Disconnect from the shortcut menu.



10.5.4.2 Disconnecting automatically



You can also set up your PC to hang up the phone automatically several minutes after your last activity online.


To find the necessary controls, right-click your connection icon (Section 9.23.3); from the shortcut menu, choose Properties. In the resulting dialog box, click the Options tab. Near the middle of the box, you'll see a drop-down list called "Idle time before hanging up." You can set it to 1 minute, 10 minutes, 2 hours, or whatever.



FREQUENTLY ASKED QUESTION


Laptop's Lament: Away from the Cable Modem



When I'm home, I connect my laptop to my cable modem. But when I'm on the road, of course, I have to use my dial-up ISP. Is there any way to automate the switching between these two connection methods?


If there weren't, do you think your question would have even appeared in this book?


The feature you're looking for is in the Internet Options
program in Control Panel (Section 9.7, page 265). Open it, click the Connections tab, and then turn on "Dial whenever a network connection is not present."


From now on, your laptop will use its dial-up modem only when it realizes that it isn't connected to your cable modem.
