我的 Intel 7260 wifi 卡在运行几分钟后就停止工作了。重新启动后卡又可以工作了,但几分钟后就停止工作了。
我已经浏览了有关此问题的所有帖子,但没有一篇包含对我有用的解决方案。
首先介绍一些背景信息。我很确定 wifi 卡是我主板的一部分,多年来一直运行良好。几周前我从 Windows 切换到 ubuntu,但问题几天前才开始出现。我最近也从 unity/gnome 切换到 i3,但互联网问题在我切换到 i3 之前就开始了。
wifi驱动是iwlwifi,我试过更新它,但是没有解决问题。运行sudo service network-manager restart
也没有解决问题。
以下是在终端中运行一些命令后的结果:
无线上网卡:
$ lspci | grep -i network
05:00.0 Network controller: Intel Corporation Wireless 7260 (rev bb)
Linux 版本:
$ uname -a

Linux 版本也是如此:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu

这些命令都是在 WiFi 停止工作后运行的:
当前连接的 wifi(尽管它实际上不起作用):
$ nmcli -t -f ssid dev wifi | cut -d\' -f2
Torpstubben2.4GHz
(这是我的网络)
可用的网络(无):
$ nmcli dev wifi

尝试扫描网络(我认为):
$ sudo iwlist scan
wlp5s0 Interface doesn't support scanning : Input/output error
enp4s0 Interface doesn't support scanning.
enp3s0 Interface doesn't support scanning.
lo Interface doesn't support scanning.
尝试关闭 Wi-Fi 并再次打开:
$ sudo ifconfig wlp5s0 down
# no return, but it ran successfully
$ sudo ifconfig wlp5s0 up
SIOCSIFFLAGS: Input/output error
省电:
$ cat /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
[connection]
wifi.powersave = 3
这个问题很烦人,原因显而易见,任何帮助解决它的帮助都会非常感激!如果您需要更多信息或我应该提供更多命令的结果,请告诉我。
