What to do about slow Wi-Fi on a modern Lenovo Yoga 530-14IKB laptop?

Question

WiFi

There is a new laptop Lenovo Yoga 530-14IKB.
Wi-Fi module Qualcomm Atheros QCA9377 Wireless Network Adapter
Windows 10, license, all updates are worth it.
The essence of the problem is that the WiFi speed is several times lower than that of any other device on the same network. Tested many times, on different networks and with different devices.
Connecting an external adapter TP-Link TL-WN822N via USB solves the problem - the speed becomes normal.
Tell me, what and how to replace the existing adapter?

Answer 1

sometimes stupidly reinstalling wifi adapter drivers helped
