=== Setup === This section's contents are copied from [http://ubuntuforums.org/showthread.php?t=25683 a posting on Ubuntu forums]. I suspect these instructions '''don't''' work on the Apple Airport Extreme (see WifiDocs/Device/AirportExtreme) 这部分内容引自[http://ubuntuforums.org/showthread.php?t=25683 Ubuntu论坛的一个帖子]。我怀疑这些在苹果的Airport Extreme(见 WifiDocs/Device/AirportExtreme)上是不工作的。 Broadcom wireless cards are tricky to set up in ubuntu, and the forums are full of frustrated users seeking advice. Broadcom provide no Linux support (feel free to complain to your hardware vendor or choose a different card if you haven't yet shelled out your cash), but they can be made to work - and you're in the right place if you want to know how. Broadcom无线网卡在Ubuntu下要谨慎的设置,论坛中充满沮丧的使用者在寻求建议。Broadcom不提供Linux的支持(如果你还没有付费,你可以向你的硬件提供商报怨或者选择其它的卡),但它确实是可以工作的-如果你想知道怎么做,你就来对地方了。 First, you need to find out if this How To is for you. Broadcom wireless cards come under many brand names and, in particular, are used in many Dell and Acer laptops. Look for the drivers supplied with your card (Dell usually store a copy in `C:/DRIVERS/NETWORK/ADDON`); if you have a file called `bcmwl5.inf` or `bcmwl5a.inf` then keep on reading. You won't succeed without following these instructions! 首先,你要明白这个介绍是否适合你。Broadcom无线网卡编入到许多商标名称,尤其是在许多的Dell和Acer的笔记本电脑中,这种情况更为明显。寻找你网卡所提供的驱动(Dell机器通常在C:/DRIVERS/NETWORK/ADDON/目录中保存一个拷贝);如果你有名字是bcmwl5.inf或bcmwl5a.inf文件的话,继续读下去。不看下面的指导,你就不能正确的配置。 * Before you start, clear out any mess from existing failed attempts to use ndiswrapper. Note that you shouldn't use a root terminal to execute the code in this how-to; use a normal terminal session instead. * 开始前,清理掉以前使用ndiswrapper的失败尝试。注意,不要使用root用户终端执行本篇指导中的代码;请使用正常的终端。 <pre><nowiki> sudo modprobe -r bcmwl5 sudo rmmod ndiswrapper sudo apt-get remove ndiswrapper-utils sudo rm -r /etc/ndiswrapper/ sudo rm -r /etc/modprobe.d/ndiswrapper </nowiki></pre> Some of these steps may report errors; just ignore them. 这些步骤可能会报错;忽略出错信息。 * Copy the `bcmwl5.inf` and `bcmwl5.sys` files to your desktop. 拷贝bcmwl5.inf和bcmwl5.sys文件到你的桌面上。 * Follow the advice given at [http://ubuntuguide.org/#extrarepositories How to add extra repositories]. 接下来参看[http://ubuntuguide.org/#extrarepositories 如何添加另外的源]。 * Open a terminal session and enter this code. Note that you need an active network connection for this to work; I've assumed that if you have access to a wireless LAN, you also have access to a wired network as a fallback. 打开终端,输入如下代码。注意,这部分需要一个活动的网络连接;我假定你可以访问无线局域网,作为应急办法你也能访问有线网络。 <pre><nowiki> sudo apt-get install ndiswrapper-utils sudo ndiswrapper -i ~/Desktop/bcmwl5.inf sudo ndiswrapper -m for conffile in /etc/ndiswrapper/bcmwl5/*.conf; do sudo cat $conffile | sed -e 's/RadioState|1/RadioState|0/' > $conffile done </nowiki></pre> * Reboot your PC. On restarting, the light on your wireless card should come on. If not, try entering 重启你的机器。在机器启动的时候,你的无线网卡的灯是亮的。如果不是,请尝试输入 <pre><nowiki> sudo modprobe ndiswrapper </nowiki></pre> * Your card is now working. Open the networking configuration tool '''System''' --> '''Administration''' --> '''Networking'''. 现在你的无线网卡已经工作了。打开网络配置工具 系统-->系统管理-->网络。 * Select your wireless network card (probably `wlan0`) and hit the properties button. 选择你的无线网卡(名字可能是wlan0),点击属性按钮。 * Tick the ''This device is configured'' box, and enter your network name and connection settings. Ask your office network administrator for support if you don't know what this question means, or copy your settings from Windows. 钩选上启用此连接,输入你的网络名称和连接设置。如果你不知道这些问题,从你的网络管理员处得到帮助,或者参照Windows系统下的设置。 * BE CAREFUL entering your WEP key, if you're using one. You're expected to enter this in hexadecimal form; if you don't speak hex, prefix your key with s: 如果你使用WEP,请小心输入你的WEP密钥。你应该输入十六进制格式;如果你不使用十六进制,你的密钥前缀是s: * Click OK. The screen should close fairly quickly; if it hangs, you probably aren't connected properly. 点击确定。当前对话框很快关闭;如果不是,你大概不能正常的连接。 * Back in the Network Settings screen, select your wireless device as the default gateway device. 返回网络设置,选择你的无线设备作为默认网关设备。 * Click OK. Again, the screen should close fairly quickly. 点击确定,对话框快速关闭。 * Enjoy wireless nirvana. If everything works, you can delete the `bcmwl` file from your desktop. 体味无线天堂的乐趣吧。如果每件事情都顺利的话,你可以删掉桌面的bcmwl文件了。 * You might notice that the signal strength applet doesn't work properly. This is a known bug with these cards. 你可能会注意到信号强度工作不正常。这是这些卡的已知错误了。 If you have trouble, try booting into Windows - if you dual boot - and checking that the card is enabled. Some laptops allow the wireless card to be switched off, usually with a special key combination, and I've not found a reliable way to make this work in Linux. 如果你有问题,启动到Windows系统-如果你是双操作系统-检查网卡是否工作。有些笔记本电脑的无线网卡是可以关掉的,通常这是特殊的暗码,我没有找到在Linux下可靠的解决办法。
