我使用 Ubuntu 14.04，并使用系统托盘中的网络管理器连接到 wifi。wifi 工作正常，但 5 分钟后我失去了互联网，但我仍然连接到 wifi，我需要重新连接网络才能再次上网。我从 wireless_script 发送日志。我希望有人能帮助我解决这个问题。非常感谢！

答案1
安装常见的wifi驱动：
sudo apt-get install build-essential libssl-dev linux-headers-`uname -r` linux-firmware-nonfree`
答案2
可能是能量控制问题。请尝试关闭界面上的能量控制：
sudo iwconfig wlan0 power off
更改wlan0为您的实际接口名称。
注意：每次连接到网络时都必须执行此操作。
