When I am playing my PS4 my internet is perfectly fine with no problems. Yet when I go on my PC it takes forever to load pages and I cannot even download a game off Steam. When I try and download it game the download fluctuates from 5mbps to kbps... Yet I run a speed test for my internet and the download speed is at 26kbps. I have a couple years old PC custom built which is quite fast. Why is my internet being so weird? I have a USB wifi adapter.
