不稳定的 Wi-Fi Ubuntu 14.04 LTS

不稳定的 Wi-Fi Ubuntu 14.04 LTS

最近,我安装了 Ubuntu 14.04 LTS,因为不喜欢 Windows 8,在安装 Windows 7 时遇到了麻烦。顺便说一句,我是 Ubuntu 的新手!我的问题是 wifi 连接很糟糕,我根本无法连接!但第一次安装时确实能连接,但之后就再也连接不上了

我试过了:

  1. 删除 wifi 配置文件并重新连接
  2. 重置网络管理器

不知道还能做什么。

答案1

在内核驱动程序设置中添加此选项

$ sudo echo'选项 iwlwifi 11n_disable=1'>> /etc/modprobe.d/iwlwifi.conf

然后重新启动系统,这必须解决 wifi 问题。

答案2

echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf

使用此代码行+重新启动笔记本电脑,现在我的无线网络连接稳定:)
