我刚刚进行了全新安装,覆盖了我的旧 Windows。我基本上是个新手,不知道从哪里开始。我尝试阅读一些看似相关的答案,但发现它们都有点令人困惑,提问的人似乎比我更了解使用终端代码等,我不想冒任何风险。
目前,我正在使用以太网电缆进行全面更新 - 希望这可以解决问题,但从我在适配器上看到的问题来看,我怀疑它可能不会解决。
我的无线适配器是 Qualcomm Atheros AR9485 无线网络适配器。
当我进入网络设置并尝试打开无线时,它会打开半秒钟然后关闭。
考虑到我是一个完全的新手,有人能帮助我让无线网络正常工作吗?

答案1
模块 asus_nb_wmi 是否已加载?请检查:
#lsmod | grep asus
如果是,请尝试一个驱动程序参数:
#sudo -i
#echo "options asus_nb_wmi wapf=0" > /etc/modprobe.d/asus.conf
#exit
重新启动并查看Fn+F2行为是否发生变化。如果没有,请再次尝试上述序列,但使用整数 1 或 4。
答案2
尝试rfkill list
$ rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
1: asus-wlan: Wireless LAN
Soft blocked: no
Hard blocked: no
如果显示某些设备被软阻止,请运行rfkill unblock ID
ID 为设备编号的命令。您的解决方案是运行:
sudo rfkill unblock all
还可以尝试使用键盘打开/关闭天线。在我的笔记本上,它有时会有所帮助。我使用Fn+F11和弦。图标看起来像三叉或收音机——正如 ChrisR 所说。
如果显示设备硬阻塞,您应该拔下笔记本电脑的电源,取出电池,然后按住电源按钮一会儿,然后尝试。
解决方案
将以下内容逐行复制并粘贴到终端中:
sudo modprobe -r acer-wmi
cd /etc/modprobe.d
sudo nano blacklist.conf
然后blacklist acer-wmi
在文件末尾添加新行。
保存并重新启动。
答案3
我不确定我的答案一定有效,但你可以试一试。实际上,无线问题已成为 Ubuntu 12.04 中的一个常见问题,当我安装 Ubuntu 12.04 时也遇到了这个问题。以下是我为使其正常工作所做的事情:
- 首先连接任何有线互联网连接或 USB 加密狗;需要下载驱动程序,而且这只是一次性工作。
打开终端并执行此命令:
sudo jockey-gtk
该应用程序将搜索所有可用的驱动程序,如果缺失则尝试下载并安装。
- 一旦成功完成,您将发现一些无线驱动器已安装。只需重新启动系统一次即可。
希望它对你也有用。回复发生了什么!
