关于Ubuntu14.04.3安装完成后WI-FI驱动（BCM43142）没有的问题 (续,转)

STA - No Internet access

If you do not have any other means of Internet access on your computer, you can install the bcmwl-kernel-source package from the restricted folder under ../pool/restricted/b/bcmwl on the Ubuntu install media.

上面这段意味着你需要一个安装镜像

Note: The bcmwl-kernel-source package depends on the linux-headers packages so you may need to first retrieve the appropriate package(s) from the online repositories. A running LiveCD/LiveUSB environment has these packages (allowing the wireless to work), but an installed system may not. Make sure you have the linux-headers package that matches your current kernel version, plus the appropriate generic header packages so that they are automatically updated on a kernel upgrade. To find out your current kernel use the command:

uname -r

To find what linux-headers packages you have installed use the command:

dpkg --get-selections | grep headers

Systems installed from CDROM can add the install CD as a package source and install bcmwl-kernel-source using apt-get as above. However, if you want to do it manually then the instructions are as follows:

Navigate the install media and install the packages listed below by double clicking OR install the packages consecutively from a Terminal (in the commands below the install media is mounted at /cdrom, but yours maybe different):

可以忽略上面

../pool/main/d/dkms

cd /cdrom/pool/main/d/dkms

sudo dpkg -i dkms*

../pool/main/p/patch

我就是没有找到下面这个叫P的文件夹

cd /cdrom/pool/main/p/patch

sudo dpkg -i patch*

../pool/main/f/fakeroot

这步我失败了,不过我建议你可以按照顺序试试

cd /cdrom/pool/main/f/fakeroot

sudo dpkg -i fakeroot*

../pool/restricted/b/bcmwl

cd /cdrom/pool/restricted/b/bcmwl

sudo dpkg -i bcmwl-kernel-source*
