It's a laptop so it is an option to test wired. Laptops are mobile.
Try it at 10 to 20 feet from the router. The more feet, the more probably you will see WiFi issues.

There are folk that install other protection software and miss that it can cause this.
There's also torrent users which come under attack from the web. I don't write at length because of how much is on the web about that.

The story is incomplete, there's some tests that help a little so try a few things before you call the maker. Get ready for that call because they will have you factory reset the laptop.
