我正在尝试使用 ubuntu 进行学习。我在我的 Sony Vaio 上安装了 ubuntu。安装成功。但我无法连接到 wifi。连接到以太网后，它工作正常。我如何连接到 wifi？
wget -N -t 5 -T 10 http://dl.dropbox.com/u/57264241/wireless_script && \
chmod +x wireless_script && \
./wireless_script
我使用了上述命令并得到了以下输出。

现在我该怎么办？
答案1
该 wifi 卡应该适用于
sudo apt-get install bcmwl-kernel-source
或者你可以从镜像站点下载http://packages.ubuntu.com/utopic/amd64/bcmwl-kernel-source/download
