网络管理器状态很可能已损坏。打开文件/var/lib/NetworkManager/NetworkManager.state
。它应该是这样的:
[main]
NetworkingEnabled=true
WirelessEnabled=true
WWANEnabled=true

将 any 从“false”更改为“true”以重新启用网络。如果您首先停止 NetworkManager,它可能会更好地工作:
须藤停止网络管理器
完成后再次启动它..或重新启动
这种情况在 Lucid 醒来后偶尔会发生。在 Maverick 中,这应该是固定的。
尝试这个:
sudo apt-get install rfkill
rfkill unblock all
我希望你的无线能立即工作。我猜你有英特尔无线网卡和惠普笔记本电脑,至少其中之一。
