需要有关 Atheros AR9285 无线网络适配器的帮助

伙计们,我的 wifi 没法用了。我使用局域网工作了很长时间。但是,明天我急需能用的 wifi。救命 :))

我尝试过的事情:

  • 检查 BIOS - wifi 已启用
  • 尝试多次点击 fn + wifi 按钮

我的输出lspci | grep Wireless是:

02:00.0 Network controller: Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express)(rev 01)

命令iwconfig显示我的局域网,但不显示 wifi。

命令uname -r输出:

4.2.0-36-generic

和 ubuntu 14.04 64位。

我在网上找到的建议没有帮助,准备提供任何输出,希望得到您的帮助;)

感谢和问候。

更新: 输出:

lspci -nnk | grep -iA2 net; rfkill list all

答案1

我的联想 G50 有一个飞行模式按钮(F7 键上的飞机图标)。按 Fn+F7 可关闭我的 wifi。这或许可以解释他的 wifi 处于“硬阻止”状态。

答案2

我会首先在软件源设置窗口中检查您的受限驱动程序。然后我会启动 Ubuntu(如果您的系统已升级)或 Fedora 的实时磁盘,看看它们是否能识别您的 wifi 并正常工作。如果两者都不起作用,并且您有一个额外的硬盘和一个 Windows 磁盘,请尝试在额外的驱动器上安装它,看看在安装驱动程序后 Windows 是否可以使用它(更像是计算机商店测试)。

如果以上方法都不管用,而您的 WiFi 确实在某个时候能用,那么您的 WiFi 卡可能有问题。您可以去电脑店,要求试用他们有的任何额外卡(他们有很多),然后购买能用的。不要让他们把卡拿到后面,在柜台上换掉。这样速度更快,而且只要把卡拿到后面,他们就会收取额外费用。

答案3

由于这是使用 ideapad_laptop 模块的联想笔记本电脑,请执行以下操作作为临时解决方案

echo "blacklist ideapad_laptop" | sudo tee /etc/modprobe.d/ideapad_laptop.conf
然后重启

ideapad_laptop 模块存在错误,在某些联想电脑上会错误读取 rfkill 状态。内核开发人员已向模块添加了一个怪癖表,以便 rfkill 可以正常工作。

我可能能够利用以下结果做出更好的解决方案

sudo dmidecode | grep -i version
请编辑您的答案以添加结果
