我有一台华硕 U56E 笔记本电脑，开机一段时间后会断开无线连接并显示错误。我四处寻找解决方案（例如是否有需要安装的驱动程序），但无济于事。这发生在全新安装的 Ubuntu 16.10 上。
连接有时会断开并出现此错误。或者在启动我的笔记本电脑时，它根本无法工作，我仍然会收到相同的错误。
希望这也能有所帮助：

答案1
添加此内容：
options iwlwifi bt_coex_active=N
到/etc/modprobe.d/iwlwifi.conf。
使用命令sudo gedit /etc/modprobe.d/iwlwifi.conf。
如果此方法不起作用，请尝试运行以下命令：
sudo service network-manager restart
如果这仍然不起作用，请尝试
sudo apt-get purge network-manager
然后
sudo apt-get install network-manager

我在 Intel 8265 上遇到了严重的 wifi 问题。
解决方案是禁用设备上的电源管理。
也许这对你的情况有帮助。
创建：/etc/network/if-up.d/wifi-powerman-off
启用：chmod +x /etc/network/if-up.d/wifi-powerman-off
注意：替换<<接口名称>>使用您的 wifi 设备名称（例如wlp1s0）
wifi-powerman-off：
#!/bin/sh
IWCONFIG=/sbin/iwconfig
WLAN_IFACE=<<interface name>>
if [ ! -x $IWCONFIG ]; then
exit 1
fi
if [ "$IFACE" = $WLAN_IFACE ]; then
$IWCONFIG $IFACE power off
fi
