Laptop can't use Wi-Fi in Ubuntu 20.04 [duplicate]

My laptop is Lenovo Legion Y530 (i7 8th - 16GB ram - GTX1050). I'm running Ubuntu 20.04 for it and I was had a trouble with Wi-Fi. When I turn on Ubuntu, Wi-Fi doesn't found any modem.

I tried:

lspci -knn | grep Net -A3; rfkill list

This outputs:

The output of sudo lshw -C network is:

Попробуйте, у меня Lenovo 530s с rtl8822be и у меня работает. Вы должны быть пользователем root.

После установки не забудьте выполнить команду sudo apt-get update .

Иногда вам следует установить дважды.

После первой установки, если она не работает, запустите команду ./ make clean и установите снова.
