USB无线网卡重启后NetworkManger列表不出现问题

giveup · **发表于 :** 2016-11-02 12:53

联想Yoga 13本子，使用内置的RTL8723AU无线网卡，系统是Debian gnome sid。启动后NetworkManger列表不出现任何网卡。在命令行下执行wpa_support和DHCP能正常使用。
插入一个rtl8188的外置USB无线网卡，能出现在NetworkManger的GUI列表中，可以选择SSID，连接。如果没有拔掉USB无线网卡重新启动系统，就不再出现在NetworkManger的GUI列表里。
查看syslog，发现NetworkManger正确识别出网卡，但初始化到lo就结束了。systemed何解？

如果是正常的话，应该出现manager: (wlx2016d8570703): new Generic device (/org/freedesktop/NetworkManager/Devices/1)真搞不懂

把下面指令複製貼進終端機執行
1. sudo cat /etc/NetworkManager/NetworkManager.conf
2. sudo cat /etc/network/interfaces
3. sudo nmcli dev show
把結果全部直接選取/複製/貼上來

sudo cat /etc/NetworkManager/NetworkManager.conf

代码:

sudo cat /etc/network/interfaces

代码:

# and how to activate them. For more information, see interfaces(5).

source /etc/network/interfaces.d/*

# The loopback network interface

#iface enp8s0 inet dhcp

sudo nmcli dev show

sudo nmcli dev

代码:

似乎看不出什么东西来。是否因为systemed的udev没有正确执行coldplug?

很感谢。帮助不大。
这个问题在3.16的内核上没有出现。但是xrog驱动在笔记本上不正常，亮度无法保存，经常黑屏。升级到4.x内核，这个问题就出现了。现在只好写个脚本，连接固定WIFI。不是很方便。
