Ethernet shows higher Mbps to Internet but barely loads anything
After getting a new computer (prebuilt with new specs), my Ethernet barely runs anything. Videos play at the lowest quality and still struggle to play, I can’t play games, etc. Internet speed tests show Ethernet runs at 679.8 Mbps download and 20.2 Mbps upload, while my Internet runs at 227.5 and 13.7 respectively. My Ethernet cable is a Cat6 flat cable and was only bought a few months ago, and ran well on my previous computer, plus it runs through a splitter. If anyone has ideas as to why it runs everything terribly yet displays high speed please let me know, I’m happy to answer questions. Thank you!
Edit: after messing it seems to be more of problem with web browsers and things like discord streams. Only have this problem when on Ethernet, though. Things like YouTube videos CAN run but at a considerably slower level than Internet, as in barely being able to play even while at low graphics, while on Internet videos can run at max quality with no issues. Trying other browsers does not seem to change the issue.
