无线 7265 无法在 ubuntu 16.04 + Asus K401U 上运行

我刚买了一台华硕 K401U。除了 Wifi 无法与 Ubuntu 16.04 配合使用之外，这台电脑的网络状况非常好。虽然大楼内有 Wifi，但我的电脑上仍然什么都看不到。

下面，我收集了一些诊断信息：

我会非常感激您的帮助。如果您需要我回复更多信息，我会尽快回复。

也可以看看英特尔无线完全不工作，无法在 Ubuntu 15.10、华硕 ZenBook UX305 上使用英特尔 AC 7265 连接 wifi（似乎没有一个可靠的答案）

答案1

编辑：

  1. 关闭您的电脑，使其进入睡眠模式。
  2. 重新打开它：它将被唤醒并且 wifi 将正常工作。不要问为什么。只需这样做即可。

上一个答案：

好的。rfkill 是你的朋友。

rfkill - tool for enabling and disabling wireless devices

SYNOPSIS
       rfkill [options] command

COMMANDS
       ...

       block index|type
              Disable the device corresponding to the given index.  type is one of "all",  "wifi",
              "wlan", "bluetooth", "uwb", "ultrawideband", "wimax", "wwan", "gps", "fm" or "nfc".

       unblock index|type
              Enable  the  device corresponding to the given index. If the device is hard-blocked,
              e.g. via a hardware switch, it will  remain  unavailable  though  it  is  now  soft-
              unblocked.

因此要软解锁所有：

sudo rfkill unblock all

到硬解锁， 寻找键盘上的按键或硬件开关。对我来说，它是带有飞机图标的 F2。按此键。之后：

$rfkill list 
1: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
2: asus-wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
3: asus-bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: no
4: hci0: Bluetooth
    Soft blocked: yes
    Hard blocked: no

答案2

嘿大家，我正在使用华硕 K501U 和 Ubuntu 16.04。

安装 Ubuntu 后，我发现我的 wifi 被禁用了，这是由硬阻塞问题引起的。

我发现“拍拍电脑并打开”解决方案胡戈尔普兹工作中。

但随着我不断搜索，我发现下面的解决方案也适用于我：

echo "options asus_nb_wmi wapf=1" | sudo tee /etc/modprobe.d/asus_nb_wmi.conf

原始帖子是Asus k501U Wifi 被封
