  1. Ethernet Suddenly Slow?

    Hi, I was installing my new SSD and I completely wiped my hard drive to start fresh and make it easier to install Windows on my SSD. Along the way, I unplugged everything from my PC to put in the new part. After I installed the SSD everything worked fine (it still is), but I noticed a significant drop in download speeds (10-12 MB/s to 1-3 MB/s) on every platform like Steam, browsers, and other services. A speed test I ran supported this because I had way lower numbers than before. Does anyone know what might be causing the issues?

    I have D-Link Power Ethernet.

    Edit: This is a desktop.

    IP configuration not valid - interference from ethernet adapter?

    Solution 1: No Internet Access In Windows 8.1or Windows 10

    Step 1:

    Go to Device Manager → Network adapters.
    Step 2:

    Expand it (Network adapters).

    Step 3:

    Select your network adapter

    Step 4:

    Right click on your wireless network adapter or Ethernet adapter and then tap “Update Driver Software”.
    (in this case your network adopter is Ethernet adopter so tap your Ethernet adapter)
    Step 5:

    Now on a new window you will need to click on “Browse my computer for driver software”.

    netsh int tcp set heuristics disabled
    netsh int tcp set global autotuninglevel=disable

  3. Cannot connect to ethernet no valid ip configuration

    We appreciate the information you've provided. We'd like to confirm the results after following the steps on the link provided on our previous post.

    Meanwhile, to isolate your concern, we suggest that you check the following:

    • If the Ethernet port is clean.

    • If the end of RJ45 (Ethernet cord) is still intact.

    • If available, test the RJ45 (Ethernet cord) to your other device and check if issue persists.

    We look forward to your reply so we can assist you further.

  4. Ethernet Suddenly Slow?

    Lenovo laptop suddenly slow

    I have a new Lenovo E580 laptop (bought January 2019) which suddenly started to run very slow. I have especially noticed it with build times in Visual Studio and loading times for a local website in IIS.

    I have tried to reinstall Windows 10 Pro by formatting the entire computer but it’s still slow.

    Laptop spec:

    • Windows 10 Pro 64-bit
    • CPU: i7-8550U 2.00GHz
    • 16 GB RAM
    • 512 SSD

    Software where I really notice the slowness:

    • Visual Studio Community 2019 Version 16.3.9
    • IIS to Windows 10

    I have tried to setup an older laptop with the same software installed as the new laptop, to compare the loading times. The old laptop has a very similar spec. (i7-4700MQ 2.40GHz, 16GB RAM, 256 SSD). The load time for a local website on the new laptop is 78 seconds where on the old is 30 seconds. On the new laptop it used to be around 30 seconds as well.

    It’s not just Visual Studio and IIS that is slow it’s the entire laptop. I thought it would be fixed by reinstalling Windows but there were no improvements. I suspect it’s a hardware issue, but I don’t get any errors, and everything looks fine.

    Does anyone have suggestions to what I can try to pinpoint this issue or is it better to contact Lenovo support, as the new laptop is still under warranty?
