Hey all-- on wifi, I’m getting 477 mbps down, 330mbps up with a 9ms ping on speed test dot net.

On ethernet, I’m getting double that: 916 mbps down, 882 mbps up with a 4 ms ping.

But those data points don’t tell the whole story. While those results would lead me to believe I’d get better real world performance via ethernet streaming video and browsing social media platforms like X, that’s not what is happening.

When connected via ethernet, videos are buffering and images on X aren’t loading. When connected via wifi, it’s a much better internet experience without the buffering.

What could be the cause of poor real world internet performance on ethernet and better performance on wifi?

Thanks!

    It Sound like paketloss all streaming media uses the UDP protocol that doesn’t have any error control. If the network cable is bad och squeezed it can result in buffering and paketloss. Try change the cable!

    I have a 300 mbps symmetric fiber and my ethernet-connected devices (TVs, PCs, Laptops, PS5, etc.) are working perfectly; I’m not experiencing buffering at all.

    There are a lot of factors that may be causing your problems, such as bad cables, bad ethernet/NIC of your PC/Device, ISP issues (such as Verizon FiOS wherein the Nokia ONT cannot handle malformed IPv6 packets causing issues), etc. If you can give more information about your network topology, we **may** be able to pinpoint what the problem is.

      Thanks u/JuicyCoala. I have fios. I’ve tried 2 different ethernet cables and experience the same issue-- when plugged directly into the Fios router/modem unit and directly to a switch as well.

    Bad cable.

    Tcp works cause of error correction (speed test).

    Udp do not work, cause no error correction.

    You didnt play with values like mtu etc right?
