求助大神: ubuntu无法自动开启wifi功能!

[pz239]

系统信息:

神舟精盾K480A, Xubuntu 18.04(内核5.0.0-26-generic), xfce 4.12

问题描述:

每次开机后系统无法自动启用wifi(显示'wifi已通过硬件开关禁用'), 必须手动通过"fn+F2"开启后, wifi才可用.
但是一旦系统休眠后唤醒或者重启, wifi又会显示被禁用, 每次都需要手动开启, 非常麻烦. 能否通过配置, 使系统在重启或唤醒后自动开启wifi功能, 而无需手动开启?

ps:

先前在网上查询后, 得知该问题有可能是多个wifi驱动模块冲突所致, 但是通过'rfkill list all'命令查看, 本机上只装有一个wifi模块:

rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: yes

另外, 使用命令:'sudo rfkill unblock all' 解锁wifi, 依然无效!

该问题已困扰我许久, 求各位大神指教!!!!

hard blocked不是rfkill能解锁的了的。

不存在多个wifi驱动模块冲突这种事。只有过针对特定笔记本的驱动错误地关闭了wlan的硬件开关。但你的情况又不大像。

先看看你的无线网卡具体是什么型号。把下面两个命令的结果发上来

代码： 全选

sudo lshw -C network
lsmod

你也可以到bios里去看看有没有跟wifi或电源管理相关的选项，调整一下试试

多谢版主出手相助，以下是我在手动开启wifi后，两个命令的执行结果：

先试一下给驱动加一个配置参数

代码： 全选

echo "options ath5k nohwcrypt" | sudo tee /etc/modprobe.d/ath5k-nohwcrypt.conf

然后重启，看看能否解决。

如果不能解决问题，执行下面命令删掉配置

代码： 全选

sudo rm /etc/modprobe.d/ath5k-nohwcrypt.conf

再看看被hard blocked的时候运行下面命令能否解除锁定

代码： 全选

sudo rmmod -f ath5k
sudo rfkill unblock all
sudo modprobe ath5k

[pz239]

版主大大, 我试了你说的两个方法, 貌似都不起作用...,

我给驱动加了配置参数, 重启后, wifi还是关闭的,然后删了驱动配置, 执行以下命令时报了错误:

pz@pz-Laptop:~$ sudo rmmod -f ath5k
rmmod: ERROR: ../libkmod/libkmod-module.c:793 kmod_module_remove_module() could not remove 'ath5k': No such file or directory
rmmod: ERROR: could not remove module ath5k: No such file or directory
pz@pz-Laptop:~$ sudo rfkill unblock all
pz@pz-Laptop:~$ sudo modprobe ath5k

[astolia]

我看错了，把所有命令中的ath5k改成ath9k，从头重试一下

[pz239]

改过之后试了几次, 还是不行...

先用 echo "options ath9k nohwcrypt" | sudo tee /etc/modprobe.d/ath9k-nohwcrypt.conf 添加驱动参数, 重启后, wifi无法自动开启. 手动开启wifi后, 依然无法连接....., 使用'rfkill list all'命令查看, 发现输出居然为空...

使用 sudo rm /etc/modprobe.d/ath9k-nohwcrypt.conf 删除配置, 重启后手动开启wifi, 连接恢复正常. 然后再手动关闭wifi, 顺序执行 sudo rmmod -f ath9k sudo rfkill unblock all sudo modprobe ath9k 3个命令, 没有任何输出, 且wifi依旧无法开启, 手动开启后连接正常.
