我花了几个小时试着让我的无线电话卡正常工作。我把PCI卡从一台工作机器搬到了新的。都运行Ubuntu12.04。这张卡在第一台机器上运行良好,但现在却找不到任何无线网络。我使用的是wl驱动程序,因为它被告知正在使用BCM4321芯片组。我使用这个页面作为安装指南:https://help.ubuntu.com/community/WifiDocs/Driver/bcm43xx#A12.04_.28Precise_Pangolin.29_-12.10.28Quantal_Quetzal.29
我希望有人能给我一个建议来帮助我的痛苦:)下面的细节。
dmesg (BCM4329看起来可疑,因为芯片组应该是BCM4321):

你有三种可能的解决方案
sudo nano /etc/modprobe.d/blacklist.conf,然后添加blacklist b43并从黑名单中删除brcmsmac。然后转到sudo nano /etc/modules并添加wl或brcmsmac。后者在我的电脑上工作。我也有broadcom,但不是同一个。`
