我的电脑也是这个型号,也遇见了这个问题,我试过到4.9还是正常的,之后的版本全有这个问题,另外我用的是 Manjaro
发行版,网上只搜到了这一个报这个问题的地方。blacklist添加后就能打开wifi了。

Title:
  acer电脑无法启动wifi

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  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。。。
