HP Pavilion g6。Ubuntu 12.04。内核 3.5.0-39。Wifi/蓝牙突然停止工作

直到昨天，WiFi 都运行正常。突然出现问题 - 我甚至无法在 GUI 顶部菜单上看到“启用无线”选项。

以下是信息：

iwconfig 给了我这个：

eth0      no wireless extensions.

lo        no wireless extensions.

ifconfig 给了我这个：

最近的更新之一是更新的内核版本，称为 linux-image。手动安装驱动程序时，您仅为当前正在运行的内核版本编译它。现在您必须为较新的内核版本构建驱动程序。请打开终端并执行以下操作：

cd Desktop/DPO_RT3290_LinuxSTA_V2600_20120508

...或者您下载并提取最初用于编译驱动程序的文件的位置。

make clean
make
sudo make install
sudo modprobe rt3290sta

您的无线网络现在应该可以正常工作了。每当安装新内核版本时，请重复此过程。
