我的 HP-EliteBook-745-G2 上安装了 Ubuntu 18.04 和 Windows 10 双启动,由于某种原因,我似乎无法通过 WiFi 适配器找到 WiFi 网络,但以太网可以工作(但是,如果我关闭屏幕并返回笔记本电脑,以太网就会停止正常工作,迫使我重新启动笔记本电脑才能使用以太网)。
我做了但没有效果的事情:
卸载内核并重新安装。
尝试使用
rtlwifi.new
作为修复。尝试通过隐藏网络连接不同地方的不同网络。
重新安装了 Ubuntu。
sudo service network-manager restart
因此我想我应该创建一个新帖子来获得不同的视角。
旁注:WiFi 在 Windows 端运行正常,这些问题仅在我的 Ubuntu 启动时存在。
输出结果为lshw -C network
:
$ sudo lshw -C network

编辑:仅对于使用编辑来纠正我的语法的人来说,“I'd”与“I would”相同。
另一项编辑:运行rfkill list all
,结果如下:
$ rfkill list all

Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
2: brcmwl-0: Wireless LAN

然后运行:dmesg | grep wl
生成:
$ dmesg | grep wl

答案1
我在使用 Ubuntu 16.04 时遇到过几次问题,重新启动网络管理器总能解决问题。
所以请尝试
sudo service network-manager restart
答案2
在我们找到确切问题之前,这只是部分答案。随着我们的进展,我将编辑答案以提供进一步的步骤。
首先,不需要 Realtek 驱动程序的 conf 文件;请将其删除:
sudo rm /etc/modprobe.d/rtl8723de.conf
第二,你的/etc/network/interfaces
文件有问题,请修改:
sudo nano /etc/network/interfaces
将文件修改为:
# interfaces(5) file used by ifup(8) and ifdown(8)
auto lo
iface lo inet loopback
保存(Ctrl+o 然后按 Enter)并退出(Ctrl+x)文本编辑器。
重新启动并告诉我们是否有任何改进。

我建议您尝试同样的做法:
