编辑：
我将监管区域改为美国。然后我更新了固件：
cd /lib/firmware
sudo wget https://github.com/OpenELEC/iwlwifi-firmware/raw/master/firmware/iwlwifi-7265D-21.ucode
之后它看起来仍然是同一个版本

Hard blocked: no
并且：
hp_wmi 16384 0
acer_wmi 20480 0
您的计算机没有两个都一台 Acer 和一台 HP！让我们卸载并列入黑名单宏碁wmi模块。
sudo -i
modprobe -r acer-wmi
echo "blacklist acer-wmi" >> /etc/modprobe.d/blacklist.conf
exit
您的无线网络现在应该可以正常工作，但可能需要重新启动。
答案2
chili555 的答案对我也有效！太新了，无法评论，但我认为让大家知道这个答案对同一台机器上相同硬件的多个人有效很重要。我还尝试了以下方法，效果不错...
sudo -s
pico /etc/modprobe.d/blacklist-ua-acer-wmi.conf
(Add the following content)
blacklist acer-wmi (save and close file)
init 6 (to restart)
