[Lenovo G50] WiFi problems in Ubuntu, how to fix?

Question

ubuntu

Hello. There is a laptop, Lenovo G50. It has Ubuntu installed. The problem is that after 1-2 minutes of stable operation, WiFi fails safely. And this problem persists in all distributions based on Ubuntu (eg Elementary OS). Search results on the forums did not give a clear answer. I would be grateful if anyone can help. Thanks in advance.

The driver out of the box also had problems on Ubuntu 14.04 - it worked, but there were strange disconnections and heavy reconnections.
The change of the card driver (rtl8192cu) helped - I installed it from a third-party repository.
Now everything works flawlessly.
