The WiFi on my new PC sucks, but it’s fine on a laptop right next to it

I have a brand new PC that when ran on a speed test for the wifi, it comes back 10MPS, however in the rest of the house we’re getting in the hundreds, and when I put a phone or laptop next to the PC and run the same exact test on the same website, it also comes back in the hundreds. I have photos but it won’t let me post, please help
