我最近升级到了 14.04，我发现在连接到 wifi 网络一段时间后，我的电脑突然断开连接，我必须禁用 wifi 然后再次启用才能连接。这对我来说是个大问题，尤其是在下载文件时。有什么解决办法吗？除了其他修复方法外，我已经尝试禁用 IPv6，正如一些帖子所建议的那样。请帮忙，我的电脑运行的是 64 位。
以下是运行脚本的结果：

答案1
这个驱动程序有问题，但我们可以做一些事情来帮助它更好地运行。
首先在您的路由器中更改802.11bgn为802.11bg。
其次，将 wpa/wpa2 加密更改为 wpa2 (CCMP)(AES) 而不是 (TKIP)，如果您有该选项，效果会最好。
第三，将路由器中的无线频道设置为 1 或 11，然后保存路由器配置并重新启动。
第四，进入屏幕右上角的网络管理器，单击编辑连接>无线选项卡，并将 IPV6 设置为忽略。
第五，打开终端 CTRL+ALT+_T，然后逐行复制并粘贴以下代码以确保准确性：
echo "options rtl8192ce swenc=1 ips=0" | sudo tee /etc/modprobe.d/rtl8192ce.conf
sudo modprobe -rfv rtl8192ce
sudo modprobe -v rtl8192ce
