So, my internet slowed down after I factory reset my PC. Before the factory reset I was constantly getting ~3mb/s but after I reset my PC to windows 10 (Before Windows creators update) it's been 200kb/s or even lower, I used this tool called driver booster which downloaded most of my drivers. I have tried Ethernet as opposed to USB dongle but that just makes it even worse which didn't happen before the reset, also wifi doesn't change speed when no devices are connected.
