A couple of weeks ago, a new Wi-Fi signal started popping up on my computer and other devices, called, "pineapple sandwich." Ever since then, the Wi-Fi in my house has been awfully slow. I've tried multiple things (doing a factory reset, calling the internet company, and even buying a new router), but nothing works. Does this new WiFi have anything to do with my troubles, or is it purely based in my computer itself? Thanks for your time.
Software/Hardware used: Hp Envy, running on windows 10
