So, I've been having trouble with my internet for far too long now and I'm done with it. Time to do something. I know that the problem can't be the internet itself because it works perfect with everybody else's computers, just not mine. I tested the internet speeds of my brothers pc and mine. I had a download speed of 0.8Mbps and he had 10.8Mbps. My question is why?. He's on WiFi and I have an extender in my room connected with a cable to my pc. Does anyone have any advise to fix this problem?
