使用Intel AC 8260, subsystem 0010
(包含在lspci
下面)。
我昨天ubuntu 16.10
在新的clevo P775DM3-G
笔记本电脑上安装了wifi,并且可以正常工作。好吧,我不得不关闭蓝牙,然后wifi显示网络,连接到其中一个,然后再打开蓝牙,一切正常。
我让机器进入睡眠状态,今天早上,将其重新打开,一切都变得混乱(扭曲的显示和按键无法正常工作),因此不得不进行硬重置,现在wifi不再起作用-无法检测到周围的任何网络。我如何备份它?

编辑1:我绝对认为这与失败的暂停恢复有关。我再次尝试了暂停恢复,它像上次一样冻结了。但是我先按Ctrl-Alt-F1,再按Ctrl-Alt-F7(我以前在14.04上执行过此操作,当时台式机使用Nvidia 860M每隔几个小时便会冻结一次,以使其再次解冻),然后2分钟后, Ctrl-F1屏幕变黑,然后再过2分钟后,Ctrl-F7将其恢复,一切正常,我登录了。wifi已启用并再次检测到连接。为了确认(出于习惯)我暂停并恢复,再次出现相同的问题,先按Ctrl-Alt-F1,再按Ctrl-Alt-F7,但是这次它冻结了,在10分钟后进行了硬重置。现在回到第一个-wifi不再起作用,lshw显示它像以前一样被禁用:(。不知道这是否相关:https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1566302/comments/123
这也是请求的dmesg:http : //paste.ubuntu.com/23625894/
这是我当前使用的图形卡,以防任何人找出问题所在:

编辑2:按照@ chili555的要求下载并安装固件的新副本后,这里是新的dmesg:http ://paste.ubuntu.com/23625981/
(问题仍然存在)
在您的粘贴中,我们看到一个微代码(固件)错误。我们想知道您的固件文件是否已损坏。让我们下载并安装一个新副本。从具有有效互联网连接的终端:
wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.162_all.deb
sudo dpkg -i linux*.deb
重新启动,让我们看到一个新的粘贴:
dmesg | grep iwl
该页面建议内核版本4.3及更高版本的固件为-16版本。您的驱动程序加载-22。让我们通过重命名-21和-22来尝试加载-16,看看是否有帮助。
cd /lib/firmware
sudo mv iwlwifi-8000C-21.ucode iwlwifi-8000C-21.bak
sudo mv iwlwifi-8000C-22.ucode iwlwifi-8000C-21.bak
重新启动,让我们粘贴。
dmesg | grep iwl
