90 CHAPTER 8 GETTING EVERYTHING UP AND RUNNING USING NDISWRAPPER You might find that your wireless card is not supported under Ubuntu. While the people who write drivers for Linux endeavor to have the operating system work with all wireless cards, they often need to reverse-engineer wireless card technology, and this can mean that drivers take a while to appear. In cases such as this, it s sometimes possible to use NdisWrapper. This allows you to use Windows XP drivers for the wireless card. It s not a perfect solution, but it s certainly worth a try. Sadly, although NdisWrapper is fundamentally simple to use, there are special considerations for each card and it s not possible to provide an all-encompassing guide here. The best policy if you wish to use Ndis- Wrapper is to search the Ubuntu Forums (www.ubuntuforums.org) for a guide to configuring your particular card. It s almost certain that at least one other person will have posted a how-to tutorial. However, you should first check http://ndiswrapper.sourceforge.net/mediawiki/index.php/List to see if your card is listed among those known to work. Configuring Dial-Up Internet Access At one time, nearly all home users (and even some workplaces) used dial-up modems across phone lines to access the Internet. But since the boom in broadband courtesy of DSL and cable television, dial-up access has declined in popularity. Ubuntu has excellent support for dial-up connections but, unfortunately, only for certain modems. In simple terms, it supports many external serial modems and some internal models (including PCI and PCMCIA cards), but it doesn t directly support so-called Winmodems, which are the most popular type of dial-up modem on the market today. Winmodems rely on Windows taking care of the coding/decoding work, hence the name. This is done to save on component costs during manufacturing. The companies that make the hardware behind Winmodems aren t always helpful to the Linux kernel programmers, and it can be difficult for them to make the modems work under Linux. Yet more manufacturers provide the required drivers but under a software license that s not compatible with the GNU Public License (GPL) used throughout the rest of Linux. This means that including the software with Linux brings with it ethical and even legal issues. A project that works to bring support for most Winmodems to Linux is called Linmodems. However, the Ubuntu developers have decided not to include its software within Ubuntu at the moment. If you would like to try to make your Winmodem work under Ubuntu, visit the Linmodem project s web page, http://linmodems.org. You ll find a welcoming community of users who are dedicated to helping others get online. Alternatively, you can skip straight to the guide that s written for beginners who would like to make a Winmodem work under Linux: http://linmodems.technion.ac.il/first.html. Searching the Ubuntu forums (www.ubuntuforums.org) might also reveal useful information.
