WIFI falls off, where can I find the driver?

Question

mint

The Lenovo B575e laptop is running Linux Mint 19 Xfce 64bit.
The laptop is sharpened for Windows and, perhaps, because of this, it has network problems.
The Internet is constantly lost through wi-fi, on the forums they write that there may be a problem with the drivers.
What can you try to solve the problem? Where can I find the necessary drivers?

Here are two programs, they have all the drivers, although wi fi falls off, and there’s nothing you can do about overheating if the chipset is heating
