![不稳定的 Wi-Fi Ubuntu 14.04 LTS](https://linux22.com/image/868454/%E4%B8%8D%E7%A8%B3%E5%AE%9A%E7%9A%84%20Wi-Fi%20Ubuntu%2014.04%20LTS.png)
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:
- 删除 wifi 配置文件并重新连接
- 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:)
