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:

  • 安装 rfkill -> sudo apt-get install rfkill
  • 在终端中给出这个命令 -> 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。
