    Windows 8 Ethernet Driver Causing Slow Download Speeds


    Hey guys,

    I recently put together a new 64-bit Windows 8 Build. Everything is running fine except my Ethernet connection.

    I use the build in my office and my co-workers are consistently getting download speeds of 30+Mbps using speedtest.net. Unfortunately, my speeds were around 5Mbps.

    I narrowed down the issue to a network driver conflict. After downloading and installing the latest drivers from Realtek, my internet speeds jumped to 30+Mbps on Speedtest. The only issue is everytime I reboot the computer, the same problem occurs. I have to fiddle around with device manager disabling/uninstalling the default drivers and/or reinstalling the Realtek drivers.

    Windows keeps reverting back to the signed older driver causing the issue, instead of the newer unsigned version from Realtek.

    Anyone can help?

    My issue is very similar to this:

    But none of the solutions there seem to work

    Windows Update is probably the culprit - try disabling it (Windows key +X > Control Panel > Windows Update > Change settings), restart, and then check the drivers. If that is the problem you can either leave it disabled, which means you would have to update manually (ie., you have to initiate the Windows Update process yourself), or you can change the setting to "Check for updates but allow me to choose whether to download and install them".

    Thanks for the reply.

    Unfortunately, I've already disabled that but the problem persists after rebooting my computer

    Also do the following from a command window: ipconfig /flushdns & netsh winsock reset catalog

    Did you turn it off entirely (ie., Never install updates)?

    yes i did. I also messed around with policy settings in gpedit.msc - that only prevented me from installing the actual needed 3rd party driver.

    Ok here's what you want to do:

    First, (make sure the Windows drivers are loaded, not the Realtek drivers)


    1. Windows Key + X > Command Prompt (admin)

    2. Copy the line below, then place your cursor at the blinking command prompt and rt.click once (which will paste the command)

    pnputil -e

    3. Find the driver (should be under Network adaptors) > then type this:

    pnputil -f -d published name

    whereas published name is the name of the driver

    4. Exit the command prompt and install the Realtek drivers.

    Yes, make sure that the Windows drivers are loaded before you do it because the command will be permantley deleting whatever drivers are loaded at that point.
