I stuck it in the laptop, the folder with the driver installer opened. I launched the installer, a progress bar appeared, reached 100% and that's it, the device is working. Before that, you just need to turn off the WiFi adapter built into the laptop in the device manager. A week of active (about 12 hours a day) use has passed, there were no fall-offs, the connection keeps perfectly.
