重启后intel centrino wireless n 1030无线掉线Ubuntu 14.04

重启后我的wifi突然停止工作

sudo lshw -C network 给这个

我的wifi设备是Intel Centrrino Wireless N 1030（彩虹峰）

我尝试更改iwlwifi.conf，但对网站没有任何帮助，然后我在网站上找到了下载地址https://www.intel.in/content/www/in/en/support/network-and-io/wireless-联网/000005511.html

这些是安装固件的说明：

Copy the files into the distribution-specific firmware directory, /lib/firmware.
If the directory does not work, consult your distribution documentation.
If you configure the kernel yourself, make sure firmware loading is enabled.

请注意，除了iwlwifi-6000g2b-5.ucode文件外，还有其他两个文件不需要复制（一个是许可证，另一个是自述文件），然后又重新启动了

但是几个小时后，wifi掉线时遇到了一个新问题

dmesg | grep iwl提供了以下功能

我还参考了错误报告https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1420935尝试了以下操作创建一个名为：/etc/modprobe.d/wifi_bug.conf的文件

将以下行添加到文件中：options iwlmvm power_scheme = 1 options iwlwifi bt_coex_active = N swcrypto = 1 11n_disable = 1

将该文件的所有权设置为与该文件夹中的其他文件相同。

重启。

工作了一段时间，问题一直存在，直到现在我使用的内核版本是4.4.0-130-generic
