首次启动无法识别无线网卡

jerry79 · #1

笔记本型号thinkpad t460s，现在的问题是：首次开机通常都无法识别无线网卡，需要重启1~2次才能识别并正常联网。

我去到intel的网站上下载了最新的8260的驱动，解压后得到文件：iwlwifi-8000C-13.ucode，然而在/lib/firmware目录下，已经有了这个文件，甚至有了更新的版本：iwlwifi-8000C-16.ucode，如下图，我也不清楚系统现在使用的到底是哪个版本。
请大神帮忙看看，谢谢！

在“无法识别无线网卡”的情况下，开机后立刻执行以下指令将结果全部复制贴上来

代码：全选

dmesg | grep iwl
sudo lshw -C net
sudo rfkill list all

此为固件。驱动集成在内核中。如欲升级驱动可使用较新的内核。可尝试从 http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.12/ 下载一套 Linux 4.8.12 安装试用。或等待 16.04.2 提供的 HWE 升级包(linux-generic-lts-yakkety)发布。

Linux 4.3+ 均使用固件版本 16.242414.0

您可以考虑升级内核或降级固件。考虑到 Linux 4.1 才对 "Intel Corporation Wireless 8260" 提供初步支持，您应该使用尽可能新的内核以最大化新硬件支持。

jerry79 写了：内核暂时不敢自己升级，如果需要的话，我还是等官方升级吧。

称之为“升级”内核可能会吓到缺乏相关经验的人。不如说成是“安装一个新内核”。
若新内核使用遇到问题，再用老内核启动就是。
当然等待 Ubuntu 16.04 的下一个 HWE 升级(linux-generic-lts-yakkety) 也是可以的。
