在笔记本上安装了Ubuntu系统,用的是无线联网,可是找不到无线的信号,在网上搜索了很多信息都不管用,发现有个网友提出的方案非常有用,照做后问题解决了,现在分享如下:
先在终端中输入:sudo gedit /etc/NetworkManager/nm-system-settings.conf
把managed=false改为managed=true
重启networkmanage
sudo service network-manager restart
就行。
要是上面的文件打开是空的,可以复制下面的内容进去:
# This file is installed into /etc/NetworkManager, and is loaded by
# NetworkManager by default. To override, specify: '--config file'
# during NM startup. This can be done by appending to DAEMON_OPTS in
# the file:
#
# /etc/default/NetworkManager
#
plugins=ifupdown,keyfile
managed=true
注:联网是大问题,希望能帮助大家解决问题。
