Yoga Pro 2 Wi-Fi 无法使用

Yoga Pro 2 Wi-Fi 无法使用

我在新的 Yoga Pro 2 上安装了 Ubuntu 14.04,但无线功能无法使用。它从 Windows 8 开始。

网络管理器说 Wi-Fi 已被硬件开关禁用。

我尝试将黑名单文件放入 ect/modprobe.d 中,正如很多地方建议的那样。我将文件命名为“blacklist-ideapad_laptop.conf”,并在文件中写入blacklist ideapad_laptop

我检查了 BIOS 中无线功能是否已启用。确实已启用。

我运行rfkill list all并显示:

0: hci0: Bluetooth
         Soft blocked: no
         Hard blocked: no

2: phy0: Wireless LAN
         Soft blocked: no
         Hard blocked: yes

我运行iwlist wlan0 scan并显示:

wlan0    Failed to read scan data : Network is down

我运行sudo rmmod ideapad_laptop并显示:

rmmod: ERROR: Module ideapad_laptop is not currently loaded.

我运行ifconfig wlp1s0 up并显示:

wlp1s0: ERROR while getting interface flags: No such device.

我运行了“lspci”并显示:

01:00.0 网络控制器:Intel Corporation Wireless 7260(rev 6b)

我运行sudo lshw -c network并显示:

Intel Centrino Advanced-N 7260 没有无线功能似乎正在处理类似的问题。它建议我需要更新我的固件。所以我从英特尔网站下载了 iwlwifi-7260-ucode-23.214.9.0。我将文件“iwlwifi-7260-9.ucode”放在 /lib/firmware 中,然后再次运行“sudo lshw -c network”。它显示的内容与之前完全一样。

将 iwlwifi-7260-9.ucode 移至 /lib/firmware 后,我运行了“sudo modprobe -r iwlwifi”和“sudo modprobe iwlwifi”

安装新固件我还需要做什么吗?

答案1

这只是一个快速的想法,但请尝试以下代码:

rfkill unblock 2

我发现你的无线网络被屏蔽了
