I am having an issue thats difficult to pin down. I have Time Warner Cable (spectrum) with 100/10 Mbit/s download/upload speeds. My PC has a gigabit ethernet card and an I7 4790k cpu with a 1070 GPU, so it isn't a hardware limitation on my end, at least I don't think. I am connected via ethernet cable, and never use WIfi. I live in an apartment complex, and every night from around 7pm to 930pm I cant even watch 480p Youtube videos without buffering. It is so bad that I will pause the video, and go walk my dog while allowing it to buffer. All other times of the day and night I can watch everything on 1080p or even 1440p with no buffering. It also seems to affect my in game performance, such as in GTA 5. During those "peak" hours, I see everyone as very laggy and jumping around in game. Not smooth at all, even if my FPS is 60+. If i do a speedtest at speedtest.com during this trouble time, I get the correct download and upload speeds, but it doesn't seem to translate into real life internet use. Time Warner says there is nothing wrong, and that it must be an issue with the servers I am connecting to. I find that hard to believe because as it gets later, everything seems to speed back up. I was considering switching to At&T and paying for gigabit speeds to see if that helps, but I am not sure if that would even fix my issue. I live by myself and do not share my internet, so that shouldn't be an issue either. Any advice or insight would be greatly appreciated. Thanks!
