The speed of Wi-Fi 5 GHz fell on one of the computers
Hello. I have encountered a curious problem. On one of the computers with Windows 10, the speed dropped sharply to 10 Mbps on 5 GHz band. And 10 Mbit/s download speed, and upload speed 160-170 Mbit/s. That is, it was the download speed that dropped. I checked in different browsers. The tariff plan is 150 Mbps. Curiously, utorrent on this computer works fine and downloads at a speed of 17 mbps. Also everything is fine on the 2.4 GHz network on this computer. When checking the 5 GHz network from other devices (including mobile devices) – the speed is 150 Mbps.
I have tried reinstalling wifi stick drivers, updated network driver, uninstalled antivirus, checked PC for spyware and viruses.
Nothing has helped so far.

Hi. And if you just download the file through the browser, what is the speed? What exactly is the problem, I can’t tell you. But I would try resetting your network settings as well. Here are the instructions for Windows 10: /solving-problems-and-errors/resetting-network-settings-in-windows-10/
Since you have a USB Wi-Fi adapter (from what I understand), you can test it on another computer (laptop, disabling the built-in one). I wonder what speed it will show at 5 GHz. Also, you can connect this computer to the router via cable and check the internet speed.
