Как восстановиться, Wi-Fi соединяют интерфейсом с 'wlo1'?

После того, как я установил что-то, мое устройство интерфейса исчезается. Прежде чем я установил, я имел:

$ iwconfig

lo       ...

enp2s0   ...

wlo1     ...

Теперь это только:

$ iwconfig 

lo        no wireless extensions.

enp2s0    no wireless extensions.

Теперь я не вижу Wi-Fi. Как восстановить мое устройство интерфейса или установить другого?

Я использую ноутбук HP, Ubuntu 16.04

Я помню, что установил linux-generic пакет.

Когда я работаю:

$ lspci -nnk | grep -iA3 net; lsusb; dkms status
