重启Ubuntu 14.04后,intel centrino无线n 1030无线丢弃

我的wifi甚至在重启后突然停止工作

sudo lshw -C network给出了这一点

我的wifi设备是intel centrino wireless n 1030(彩虹峰)


我尝试更改iwlwifi.conf但是没有任何帮助然后在网站上我发现了一个下载https://www.intel.in/content/www/in/en/support/network-and-io/wireless-网络/ 000005511.html

以下是安装固件的说明:

 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,还有其他两个文件,而不是iwlwifi-6000g2b-5.ucode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

然而,几小时后无线网络出现了新的问题

dmesg | grep iwl给出了下面的内容

我已经重新报告错误报告https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1420935尝试了以下创建名为的文件:/etc/modprobe.d/wifi_bug.conf

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,问题仍然存在,因为我现在使用的内核版本是4.4.0-130-generic

从这个答案: 重置WiFi,您可以重新启动后关闭再打开WiFi。 这将模拟物理电源按钮循环关闭和适用于您的笔记本电脑。

需要硬件测试

这是适合我的解决方案
