Lab Exercise 2202: Installing and Configuring an Internet Connection
You determine that the client is currently using dial-up networking through analog modems to access the Internet Though this is probably acceptable for occasionally connecting to the Internet, these folks have a business to run! You decide to recommend either high-speed DSL or cable You explain to the client that unlike the analog modem they re currently using, the other methods use a standard NIC and an external device to interface between the DSL or cable lines Ironically, this device is usually referred to as a DSL or cable modem You will evaluate the current PCs and select one that will act as the interface to the Internet If required, you ll add a PCI network interface card, connect the DSL or cable interface, and then con gure the interface in Windows
