I have Lenovo Legion y530 laptop. I try to turn on wifi this way:

type lspci -nn | grep Network, see this wireless adapter:

Network controller [0280]: Realtek Semiconductor Co., Ltd. Device [10ec:b822]

and by [10ec:b822] I find this driver on drivers.ru, that's

Realtek 8822BE Wireless LAN 802.11ac PCI-E NIC

but there is no wifi icon in system tray, dispite the fact that network-manager-gnome installed. Okay, I update kernel to 4.19.16 as says here. After reboot, icon appears, but it says wifi off & unawaitable. By loading, log says:

failed to load rtlwifi/rtl8822befw.bin (-2)

okay, I downloaded file rtl8822befw.bin & put it into folder /lib/firmware/rtlwifi, as says here, than reboot. sign about fail to load rtlwifi disappears, but wifi still not awaitable.

What will advice to do after?

UPD: when I typing

lspci -knn | grep Net -A3

terminal returns
