今天，我为佳能Pixma MG2950安装了打印机驱动程序。因为无法在Linux中设置此打印机进行无线打印，所以我启动了Win8，并使用打印机的CD-ROM将其设置在那里。停下来一小段时间（或类似的时间）...
不知道这是否与我的问题有关，但是从那时起我再次启动freya时，我很快便在桌面上看到了是否有气泡显示“网络已关闭-脱机”。
当我单击WLAN图标时，所有条目均显示为灰色：（<< />
（连接电缆仍然有效，我获得有效的连接）
这是我系统中的一些调试信息/输出http://pastebin.com/ihTej3VL

尝试加载驱动程序，然后重新启动无线网络
> sudo服务网络管理器重新启动
如果重新启动网络管理器无效，请尝试重新启动计算机。

您是否尝试过寻找其他驱动程序？这是笔记本电脑吗？如果是，wifi硬件是否已打开？
