运行 rfkill list all 后还会出现以下内容

ajay@ajay-HP-ENVY-x360-m6-Convertible:~$ rfkill list all

请告知要执行的进一步指示

答案1

您的设备应该支持内核 4.2，Ubuntu 15.10 中已包含该版本。您可以尝试 Ubuntu 15.10（15.04 即将停用），也可以尝试将 14.04 内核升级到 4.2 版。在这两种情况下，我建议使用 Ubuntu 15.10

答案2

14.04 的支持时间更长（5 年），因此如果您要保留一段时间，这可能是一个更好的主意。至于 wifi 适配器，我发现即使无线适配器最初无法工作，如果您安装操作系统并通过以太网更新它，它应该可以解决您的问题。我再怎么强调更新部分也不为过。

答案3

入住：acer_wmi​lsmod

sudo lsmod | grep acer

如果找到它，你可以尝试卸载它：

sudo modprobe -r acer-wmi

答案4

尝试此解决方案；acer-wmi 模块有冲突，所以必须将其列入黑名单。
