I've got a gigabit internet and I can't even reach half of the speed that I'm supposed to get with my pc but my phone can get 800Mbps with wi-fi whilst my pc gets 400Mbps with wired connection. I checked my hardware so that I can be sure my pc can handle a gigabit and it doesn't seem like it's an hardware issue and since I can get 800Mbps with my phone that is connected through wi-fi, it's a software issue?
