<application>NdisWrapper</application> is considered the wireless fix-all for Linux. A great percentage of wireless adapters that are not supported natively or with other utilities are supported with <application>NdisWrapper</application>. Install <application>ndiswrapper</application> by using <application>Adept</application>. If you are uncomfortable with installation practices then it is advised that you review the <ulink url="help:/kubuntu/add-applications/">Adding Applications</ulink> document.

Once you have installed <application>NdisWrapper</application>, locate the Windows drivers either on a <acronym>CD</acronym> or the Internet. Drivers for Windows XP are preferred, however Windows 2000 drivers will usually work just as well. Once you have located the CD or the drivers on the Internet, copy them to a local folder on your system. In some instances, you may have your drivers in a <filename>driver.zip</filename> or a <filename>driver.exe</filename> file. If it the file is in a <filename>.zip</filename> format, unzip the file by either <mousebutton>right</mousebutton> clicking on the file and selecting <guilabel>Extract</guilabel> from the pop-up menu. If the file is in a <filename>.exe</filename> format, then install the <application>cabextract</application> utility and open up <application>Konsole</application> to navigate the correct directory. Once you have navigated to the directory storing the <filename>.exe</filename> file, type <userinput>cabextract filename.exe</userinput>. This will extract or unzip the file to the directory you are in. The driver will be in the <filename>.inf</filename> format, so what you will want to do is type <userinput>sudo ndiswrapper -i filename.inf</userinput> and press <keycap>Enter</keycap>. If successful you shouldn't receive any errors. This command has gone ahead and loaded or installed the drivers in the <application>NdisWrapper</application> module. To see if these drivers worked, simply type <userinput>sudo modprobe ndiswrapper</userinput> and press <keycap>Enter</keycap>. Test to see if you have a network and/or Internet connection.

If everything went well then the final step would be to load the <application>NdisWrapper</application> module by default. To do this simple type <userinput>sudo sh -c "echo ndiswrapper &gt;&gt; /etc/modules"</userinput> and press <keycap>Enter</keycap>. This will automatically start <application>NdisWrapper</application> at boot time.

88.

If everything didn't go so well, the issue may not be with <application>NdisWrapper</application> but possibly with <application>KNetworkManager</application>. To see if in fact that <application>KNetworkManager</application> was at fault, simply click the system tray icon and select <guilabel>Quit</guilabel>. Once <application>KNetworkManager</application> has closed, go back to the command line and type <userinput>sudo modprobe -r ndiswrapper &amp;&amp; sudo modprobe
ndiswrapper</userinput> and press <keycap>Enter</keycap>. This will unload <application>NdisWrapper</application> and then reload it. After you have reloaded it, test your network and/or Internet connection again.

Broadcom

90.

Since the 6.10 (Edgy Eft) release, the kernel has included driver support for some Broadcom cards utilizing the <application>bcm43xx-fwcutter</application> utility. Currently there are not that many supported cards, however development continues. To see if your card is supported please review the list at <ulink url="http://bcm43xx.berlios.de/?go=devices"/>. If your card is not included in the list, then refer to <xref linkend="network-connect-wifi-ndiswrapper"/>.

91.

To get started, the first thing you will need to do is install the <application>bcm43xx-fwcutter</application> utility. For more information on installing extra applications, please refer to the <ulink url="help:/kubuntu/add-applications/">Adding Applications</ulink> section.

92.

Once you have <application>bcm43xx-fwcutter</application> installed you can read through a list of links to various drivers for your Broadcom device. To do this open up <application>Konsole</application> (<menuchoice><guimenu>KMenu</guimenu><guisubmenu>System</guisubmenu><guimenuitem>Konsole - Terminal Program</guimenuitem></menuchoice>) and type at the prompt <userinput>zless /usr/share/doc/bcm43xx-fwcutter/README.gz</userinput> and press <keycap>Enter</keycap>. You have the choice of picking a driver from that list, driver CD, or manufacturer's website. The file you are interested in using is the <filename>bcwl5.sys</filename> file. If you have the drivers in a <filename>.zip</filename> format, unzip the files to a local directory. If the drivers are in a <filename>.exe</filename> format, you will need to install <application>Cabextract</application>. With <application>Cabextract</application>, at the command line locate the directory where you downloaded or copied the file to. Once there type at the prompt <userinput>cabextract filename.exe</userinput> and press <keycap>Enter</keycap>. This will extract the file into the directory you are in.
