1.OS : ubuntu 12.04 LTS desktop(32bit or 64bit)
H/W: Intel 7260-AC(无硬件开关)
问题: 不能联网
2.依照网上所搜寻到的答案（http://askubuntu.com/questions/331667/no-wireless-for-intel-corporation-7260-version-63）做如下动作
a.下载backports driver及firmware
b.依照指示进行安装driver及加载firmware
结果：Intel 7260-N网卡可以驱动且正常使用，但Intel 7260-AC网卡不能驱动或正常工作
3.以下是一些指令(红色部分)执行结果，请各位帮忙，谢谢！

另外请教一下，如果我想将已载入的driver停止或者卸载的话应该用哪个指令？
因我有使用过sudo modprobe -r iwlwifi希望重新加载别的驱动尝试，结果显示的是iwlwifi已在使用中"FATAL： Module iwlwifi is in use."
使用了rmmod -f iwlwifi指令也不行

使用了rmmod -f iwlwifi指令也不行
試試
sudo modprobe -rfv iwlwifi
參閱
https://gist.github.com/balupton/9891817
http://manpages.ubuntu.com/manpages/tru ... obe.8.html

試試
sudo cat /usr/share/misc/pci.ids | grep c070
溫馨提示
直接複製指令 貼上終端機執行 避免打錯字

沒有抓到網卡 MAC (類似 serial: 7c:7a:91:5f:97:90)
所以沒有分配 wlan0 無線網卡界面
未成功驅動

Supported Devices
The following devices are supported (since kernel version):
Intel Wireless 7260 (3.10)
Firmware
Intel Wireless 7260 iwlmvm 3.10+
無論是 driver 或是 firmware 都必須在 Linux kernel 3.10 以上才能獲得支援

請追蹤這一篇 看看 有沒有網友提供解決方案

建議
升級到 Ubuntu 14.04 以上版本 再試試

===>> 大概公司的网路有限定的因素，您所推荐的以下两个页面无法打开
參閱
https://gist.github.com/balupton/9891817
http://manpages.ubuntu.com/manpages/tru ... obe.8.html

我尝试了您给出的两个指令，执行结果如下：
sudo modprobe -rfv iwlwifi

test@ubuntu:~$ sudo modprobe -rfv iwlwifi
FATAL: Module iwlwifi is in use.

sudo cat /usr/share/misc/pci.ids | grep c070

test@ubuntu:~$ sudo cat /usr/share/misc/pci.ids | grep c070
8086 c070 Dual Band Wireless-AC 7260


另，您提及的驱动及firmware需要Linux kernel 3.10+的支援，这点在Intel的官网上也有提及，但由于某些限定因素，我希望可以在不升级kernel的基础上正常使用
此款7260，因此寻求帮助。而且，从官网中提供的资料，7260-N和7260-AC使用的驱动和firmware应为同样的，既然我的7260-N在同样的系统下使用同样的安装
手法是可以正常使用的，那么理论上7260-AC应该也OK才对

試試
/etc/modprobe.d/iwlwifi.conf
加上這一行在最後面
options iwlwifi bt_coex_active=N
重開機
看看 有沒有改善

藍芽有沒有打開

===>>
/etc/modprobe.d/iwlwifi.conf
加上這一行在最後面
options iwlwifi bt_coex_active=N

没有改善，还是一样的

另，我怀疑和BIOS或者WLAN本体有关，因为我安装的是Win7和ubuntu双系统
在Win7中，虽然WLAN功能是OK的，但却没有BT device

还有，我验证安装了12.04.5版本，Linux kernel是3.13+的，其结果是一样的，可以识别到WLAN，但一样
是无法联网的状态，而且，我发现在设备中查看BT的状态一直是disable的
