![Ubuntu 16.04 LTS wifi设备尚未准备好](https://linux22.com/image/1147236/Ubuntu%2016.04%20LTS%20wifi%E8%AE%BE%E5%A4%87%E5%B0%9A%E6%9C%AA%E5%87%86%E5%A4%87%E5%A5%BD.png)
我最近安装了 UBUNTU 16.04 LTS,当尝试连接 Wi-Fi 时,它显示根本没有 Wi-Fi 连接,并且显示设备未准备好。我尝试了互联网上提供的很多方法,例如:
sudo apt-get autoremove
sudo apt-get install bcmwl-kernel-source
sudo systemctl restart network-manager
另外,打开或创建/etc/pm/config.d/config
并添加SUSPEND_MODULES="rtl8723be"
,(rtl8723be
用您自己的型号替换)。
然后运行echo "options rtl8723be fwlps=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
并重启
等等,但是它们没有作用。
无论如何,当我连接以太网电缆时,笔记本电脑很容易连接到互联网。所以我假设问题出在 wifi 驱动程序上。然后我尝试此链接,但没有帮助。
我有一台配备英特尔公司双频无线 AC 7265 的 HP ENVY 笔记本电脑,以下是我执行的一些命令的输出:

如果有人能帮助我,那将非常有帮助。非常感谢。

刚好能解决这个问题,希望发布解决方案比删除问题更好。链接(https://ubuntuforums.org/showthread.php?t=2323700)包含答案。即运行
lsmod | grep acer
控制台中会出现几个条目。如果 acer_wmi 在输出中,则输入,
echo "blacklist acer_wmi" | sudo tee -a /etc/modprobe.d/blacklist.conf
然后重新启动。
希望这对某人有帮助。
