wifi无法连接

wifi输入密码后一直显示无连接。在网上看了一些文章，用RFkill list all 查看了下，发现好像无线网络被soft rfkill禁用了。
但不知到怎么搞？希望会搞的指导下

执行以下指令将结果全部复制贴上来

代码:

uname -a
lspci -knn | grep -iA2 net
sudo lshw -numeric -C net
sudo rfkill list all
cat /sys/class/dmi/id/{sys_vendor,product_name}

先尝试 sudo rfkill unblock all 看能否解除阻塞
若无效，尝试将 hp_wmi 模块加入黑名单

代码:

echo "blacklist hp_wmi" | sudo tee /etc/modprobe.d/hp-wmi.conf

后重新启动计算机。

注意，此操作可能有较大副作用。若如此操作后可解除阻塞，可再将其从黑名单中移除.

代码:

sudo rm /etc/modprobe.d/hp-wmi.conf

后重新启动计算机。
