Jef*_*ith 13 wireless realtek disconnect rtl8192ce 14.04
我刚刚在 Toshiba Satellite C655D 上安装了 UBUNTU 14.04 LTS。我的 wifi 偶尔会掉线，我要重新连接所要做的就是禁用我的 wifi 并从右上角的无线图标启用 wifi。它只是烦人。
任何帮助将不胜感激，我是 UBUNTU 的新手，但对学习 linux 命令感兴趣。幸运的是，有些命令类似于 DOS 和批处理代码。
我使用路由器，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。
这是我在论坛上找到的 wireless_script 的信息：

首先在您的路由器中更改802.11bgn为802.11bg.
其次，将 wep 加密更改为 wpa2 (CCMP)(AES) 而不是 (TKIP)，如果您有该选项，它将最有效。
第三，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。
第四进入屏幕右上角的网络管理器，点击编辑连接>无线选项卡，将IPV6设置为忽略。
现在打开终端 CTRL+ALT+_T 然后复制并粘贴以下代码一次一行，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
