升级至 12.04 LTS 后出现的问题

升级到 12.04LTS 后我遇到了一些问题。

无线现在无法连接，无线适配器显示为无人认领。

我已经sudo apt-get dist upgrade通过 Ubuntu 执行并更新了驱动程序，但都无济于事。

dpkg -S rtl* | grep /lib/modules/$(uname -r)/kernel/drivers/net/以下是评论中要求的输出：

答案1

以下答案是从我的答案中复制而来的这里。然而，该人仍然没有将其标记为正确答案。

好的，我们必须手动下载您的无线网卡的驱动程序并安装它。

步骤1

下载这并将其保存到您的下载文件夹

第2步

打开终端。要打开终端，请点击Ctrl+ Alt+ T。逐个输入以下命令并按回车键。

cd ~/Downloads
unzip rtl*
cd rtl*

步骤3

输入以下内容：

sudo make

如果此命令的输出给出提及错误的行，如下所示：

make[1]: ***[_module_/home/alaa/Downloads/rtl_92ce_92se_92de_8723ae_linux_mac80211_0006.0514.2012] Error 2 
make[1]: Leaving directory/usr/src/linux-headers-3.8.0-19-generic'
make: * [all] Error 2

...然后就此停止，并让我们知道。但如果它没有给出包含单词“error”的行，请键入以下命令：

sudo make install

步骤4

完成后，输入以下命令：

sudo modprobe rtl8192se

您不应该在这里得到任何输出（如果有，请忽略它）。检查您的无线设备是否正常工作。如果没有，请重新启动您的计算机。
