Connecting via Dial-up Modem
When all else fails, you might need to dial up to the Internet the old-fashioned way: by connecting your built-in modem to a phone cable that's plugged into a phone jack or the data port on the side of your room telephone.
You should bring your Internet Service Provider's (ISP) local, toll-free, or Internet dial-up numbers that you'll need to use while you're on the road. Be aware that most ISPs will charge an additional roaming fee to use these numbers. And, if you're staying at a hotel, you'll probably be charged additional dialing fees even for local calls.
To get a list of local dial-up phone numbers for your ISPbefore you go on the road, either visit its Web site or try looking on the List of ISPs (www.thelist.com) to see if the area you 're visiting is ser-viced by your current plan.
Though you should have created and tested your network settings options before you left home, the following section shows how to set up your laptop's internal modem to connect to the Internetmake sure that you have a modem! Take a quick peek at the back of your laptopif you see a jack with a phone icon next to it, you probably have a modem. If you don't have one installed, you can pick up either a USB-based or a PC Card modem from almost any computer hardware retailer.
What's a DNS number?
DNS (Domain Name Service) numbers are the numerical IP addresses associated with an Internet domain. Usually you know your domain by an alphabetic name, but behind all these clever names is an unmemorable address made up of numbers. Some ISPs will serve your DNS numbers to you automatically, and others require you to enter these numbers into your network settings manually before you can get online. Just to make sure you stay connected, get your DNS numbers from your ISP before you leave.

In the Telephone Number field, don't forget to prefix the ISP's dial-up number with any numbers that your hotel requires to get an outside line, and it can't hurt to place a comma before the access number so that the modem pauses briefly during dialing.

Choose either PPP or Manually from the Configure pop-up menu, as instructed by your Internet Service Provider.
