Hello. Faced with one curious problem. On one of the Windows 10 computers, the speed dropped sharply to 10 Mbps on the 5 GHz band. Moreover, the download speed is 10 Mbit / s, and the download speed is 160-170 Mbit / s. That is, it was the download speed that dropped. Checked in different browsers. Tariff plan is 150 Mbit / s. It is curious that utorrent works fine on this computer and pumps at a speed of 17 mb / s. Also, everything is fine on a 2.4 GHz network on this computer. When checking a 5 GHz network from other devices (including mobile devices) - the speed is 150 Mbps.
I tried to reinstall the wi-fi stick drivers, updated the firewood of the network card, removed the antivirus, checked the PC for spyware and viruses.
Nothing has helped yet.

Hello. And if you just download the file through the browser, what is the speed? What exactly is the problem, I cannot tell. But I would still try to reset the network settings. Here is the instruction for Windows 10: https://help-wifi.com/reshenie-problem-i-oshibok/sbros-nastroek-seti-v-windows-10/
Since you have a USB Wi-Fi adapter (as far as I understand), you can check it on another computer (laptop, disabling the built-in one). I wonder what speed it will show at 5 GHz. And yet, you can connect this computer to the router via cable and check the Internet speed.
