137 If Something Goes Wrong Connecting to the Internet ❖ Use IPCONFIG to verify that the computer has a useful IP address - one other than the private address of 169.254.xxx.xxx assigned by Windows. 1 In the Search field, type Cmd. 2 Click Command Prompt. 3 Enter IPCONFIG/ALL, and then press ENTER. The IP address for each active network adapter will be displayed. ❖ Connect your computer directly to your router or broadband modem, by plugging a standard CAT5 Ethernet patch cable (sold separately) into your computer's RJ45 Ethernet port. If your connection problem disappears, the problem lies in the Wi-Fi part of your network. ❖ If you have enabled any security provisions (closed system, MAC address filtering, Wired Equivalent Privacy [WEP], etc.), check the access point vendor's Web site for recent firmware upgrades. Problems with WEP keys, in particular, are frequently addressed in new firmware releases. Connecting to the Internet To connect to the Internet, you'll need an Internet Service Provider (ISP) and additional hardware. ❖ ISP: An ISP is a company that gives you access to the Internet. You sign up for an account with an ISP just as you do for telephone service or utilities. ISPs are usually phone companies (for a DSL or fiber optic connection) or TV providers (for a cable or satellite connection). ❖ Hardware: For a broadband connection, such as DSL, fiber optic, or cable, you may need a broadband modem. This might be included as part of the start-up hardware from your ISP when you sign up for a broadband account or you might need to rent or purchase a modem separately. If you plan to share Internet access with multiple computers by using a home network, you may also need a router. (Sometimes a modem and router are combined in one device.)

you do for telephone service or utilities. ISPs are usually
phone companies (for a DSL or fiber optic connection) or
TV providers (for a cable or satellite connection).
