无线和蓝牙无法正常工作 - Lenovo Y700

我在尝试启用无线网卡以使用 wifi 和蓝牙时遇到问题。我在 Google 上寻找了一些答案，但没有人能解决这个问题。

据我所知，这是硬封锁的问题，这里的问题是我没有物理按钮来打开它。我只有组合fn + F5，但当我按下它时软块变化。

0: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: yes
1: ideapad_bluetooth: Bluetooth
    Soft blocked: no
    Hard blocked: yes
2: hci0: Bluetooth
    Soft blocked: no
    Hard blocked: no

我也尝试过用以下方法解除锁定sudo rfkill unblock all，但没有任何变化

我尝试将其添加到黑名单，但当我这样做时，唯一可用的是2: hci0: Bluetooth

sudo nano /etc/modprobe.d/blacklist.conf 
blacklist ideapad_laptop

这是我的网络控制器

lspci -nnk | grep -iA2 net

使用命令dmesg | egrep -i 'blue|firm'我得到了该消息。

我希望你可以帮助我。

您当前使用的内核不支持您的英特尔无线网卡。为了解决这个问题，我们可以安装反向移植 

sudo apt-get install linux-headers-generic build-essential
wget https://www.kernel.org/pub/linux/kernel/projects/backports/2015/11/20/backports-20151120.tar.gz
tar -zxvf backports-20151120.tar.gz
cd backports-20151120
make defconfig-iwlwifi
make 
sudo make install
wget https://wireless.wiki.kernel.org/_media/en/users/drivers/iwlwifi-8000-ucode-25.30.13.0.tgz
tar -zxvf iwlwifi-8000-ucode-25.30.13.0.tgz 
cd iwlwifi-8000-ucode-25.30.13.0/
sudo cp iwlwifi-8000C-13.ucode /lib/firmware/

重启后 wifi 应该可以正常工作了，因为你ideapad-laptop已经将其列入黑名单了，如果你已经将其ideapad-laptop从黑名单中删除，请将其重新添加
