Wifi丢失并重新连接UBUNTU 14.04（Realtek RTL8188）
我刚刚在东芝Satellite C655D上安装了UBUNTU 14.04 LTS。 我的wifi偶尔会掉线，所有我需要做的就是重新连接是禁用我的wifi并从右上角的无线图标启用wifi。 它只是烦人的。
任何帮助将不胜感激，我是UBUNTU的新手，但有兴趣学习linux命令。 幸运的是，一些命令类似于DOS和批处理代码。
我使用的是路由器，目前其他无线设备没有问题，包括另一台运行14.04的笔记本电脑，但它是较旧的Aspire One。
以下是我在论坛上发现的wireless_script的信息：

首先在您的路由器中将802.11bgn更改为802.11bg 。
第二次将wep加密改为wpa2（CCMP）（AES）而不是（TKIP），如果你有这个选项，它将最有效。
第三步将路由器中的无线信道设置为1或11，然后保存路由器配置并重新启动它。
第四步进入屏幕右上角的网络管理器，然后单击编辑连接>无线选项卡并将IPV6设置为忽略。
现在打开终端CTRL + ALT + _T然后一次复制并粘贴以下代码一行以确保准确性：
echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf sudo modprobe -rfv rtl8192ce sudo modprobe -v rtl8192ce
我有同样的问题 – 我很懒，所以我只做了4号
“进入屏幕右上角的网络管理器，点击编辑连接>无线选项卡，然后设置IPV6忽略”
……它有效！ 谢谢
