Public bug reported:
acer aspire 4752安装了ubuntu16.04
内核4.4一切正常，升级了18.04，内核4.15，发现无法启动无线网卡，具体问题也是点击“开启wifi”，然后开启后，提示wifi已禁用，用热键开启wifi也不行。
$lspci
网卡型号是：Qualcomm Atheros AR9287 Wireless Network Adapter (PCI-Express) (rev 01)
各种方法都尝试了，最后在一个不起眼的角落里找到了方法，如下：
sudo vim /etc/modprobe.d/blacklist.conf
最后加入一行 blacklist acer-wmi #将acer-wmi驱动加入黑名单
重启即可。。。
