    Slow ethernet speed after installing Windows 8


    So I just installed Windows 8 on my gaming rig. I gotta say, after being skeptical of this whole OS for a while, installing it fresh and trying it out shows just how useful (and FAST) it can be.

    The only thing about W8 that isn't fast is my ethernet adapter. When connected, downloads are slow, pages take long to respond, videos are constantly choppy and buffering, etc. Looking at the ethernet connection in Task manager, it looks like the connection is being speed capped at 1.0 Mbps. The graph of the speed fluctuates up and down in the low range, but hits a wall at 1.0 mbps.

    This wasn't the case when I had Win 7- I could easily pull 80 Mbps on speedtest.net (Chattanooga fibre optic internet FTW). My WiFi adapter in Win 8 also does not have this problem, but I want to use the wired connection because the campus wi-fi is unreliable. I have already updated the LAN drivers, trying both the Windows- suggested driver and the one from the manufacturer website. No difference. Can anyone help me out here so I can start installing my steam games and not have it take 5 years?

    Wow! That should not happen! I have to assume that Win 8 drivers were available for your hardware LAN and you installed them accordingly. So, Win 8 is perfectly capable of delivering the same speeds you experienced in Win 7; especially over a wired ethernet connection. Now, you may wish to try or ignore my suggestions but the first thing I would do is eliminate the router from the mix by plugging my ethernet connection directly into the modem and retest. However, it is strange that your wifi does not have this issue as well. Also, you said you downloaded drivers from both Windows Update and the manufacturer's website. So, does manufacturer mean the builder of your unknown system or the manufacturer of the LAN component on your motherboard?

    One other thing. Have you downloaded the latest bios update for your unknown system and is it Win 8 compatible/ready?

    You might want to consider adding your system specs if none of my suggestions work. Good luck.

    I can't reset routers or any of that. It's campus internet. Howver, installing windows updates seems to have made it slightly faster.

    Well sounds like you are done with this issue because you haven't provided any specs for your rig so please consider marking this thread as solved because no additional concrete assistance can be provided without those specs. Good luck.
