yoga的联网问题，实在是崩溃了

[fox_pro]

我看了一下我的网卡是intel N 7260，但是试过各种驱动都没用，而且只有无线网卡。
网络连接的地方显示的是wifi通过硬件开关禁用，但是我都没有硬件开关啊。
试了firmware-iwlwifi 没用。可能是我不知道怎么激活它?
实验室要用电脑>_<，急求。

核心
3.14+
3.13 +
3.10 +
驅動不同

如果還是沒解決
從終端機
1. lspci
2. sudo lshw -numeric -class network
3. rfkill list all
4. sudo ifconfig -a
5. uname -r
把結果直接複製貼上來

[fox_pro]

第一个链接没有弄明白是要下载哪一个，第二个打不开，第三个安装把backprots--3.11-rc3-1失败了
对于ubuntu的内核的版本没什么概念，不清楚怎么弄。。。

结果是这样

該篇貼文下面的解決方法 能否幫你

[fox_pro]

按贴子上的方法试过了，可是没有什么用，是不是需要外接网卡。。。

[taohunter]

楼主请把机器具体型号提供一下，以下两种方法适用于yoga 2 pro机型，如相符可以尝试。

代码： 全选

sudo gedit /etc/modprobe.d/myownblacklist.conf

在其中添加以下一行，保存文件后重新启动系统，也许就可以了：
blacklist ideapad_laptop

以上方法是blacklist掉ideapad_laptop这个module，不想blacklist掉，也可以直接用下面的命令直接disable掉：

代码： 全选

sudo modprobe -r ideapad_laptop

[fox_pro]

yoga 2 pro 13
ubuntu 14.04
试了好像不太行

[taohunter]

yoga 2 pro 13
ubuntu 14.04
试了好像不太行

第一种方法编辑完重启后，执行以下命令，把输出贴上来：

代码： 全选

lsmod
rfkill list all

硬件开关，试试Fn-F?的组合按键嘛。

[fox_pro]

早就试过了不行- -

[iamg3]

我也是这机器，也是纠结快疯。

[taohunter]

前面楼主隔了两天回复，没看到。按照前面我描述的先禁用掉ideapad_laptop，然后再执行

代码： 全选

sudo rfkill unblock all

应该就行了。下面是lenovo国外网站上对这个问题的详细描述，有能力的话甚至可以自己编译一个驱动彻底解决这个问题：

最后google说有个模块弄坏了,重新编译了那部分内核
