mol*_*lhm 7 wireless networking drivers loop-device
我已升级到 ubuntu 16 ，然后我遇到了 wifi 问题，因为它无法正常工作，并在尝试进行开发时给我消息“设备未准备好”
$sudo ip link set wlo1 up
RTNETLINK answers: Operation not possible due to RF-kill
设备被阻止，所以我取消阻止它，然后我收到一条不同的消息
$sudo rfkill unblock wifi
sudo ip link set wlo1 up
RTNETLINK answers: Input/output error
我发现加载模块rt2800pci有问题，dmesg的输出包含该错误
