我可以使用电缆访问互联网。我有一台 HP Pavilion dv6 笔记本,使用的是 Ubuntu 14.04.4 LTS。

这里 他似乎有一个非常相似的问题,这个命令修复了它:
$ sudo apt-get purge bcmwl-kernel-source broadcom-sta-common broadcom-sta-source && \
sudo apt-get install b43-fwcutter firmware-b43-installer
但我没有 Broadcom...我可以执行类似的命令吗?

不知何故,一切都被软封锁了。解决方案:
$ rfkill unblock all
