    VERY Slow Internet After Upgrade to 10


    Can anybody solve this one?

    After upgrading to Ten, my Internet speed plunged from 18 MBPS down to barely over 1 MBPS. It's specific to Windows 10, and here's I know: I reverted back to Windows 8.1 and my net speed returned to normal. A week later, I upgraded to Ten again and poof -- my internet speed plunged right back down to 1 MBPS again. There's more:

    I have a CenturyLink modem hooked into a TP-Link router, and I also have a Linksys Range Extender. The CenturyLink modem puts out its own wireless signal, and if I connect to THAT, I get my full 18 MBPS net speed, and I get that WITH Windows 10. But when I click on the TP-Link router/Linksys range extender connection, I'm right back down to 1 MBPS again. Always.

    This happens on my desktop Dell XPS 2720 running Windows Ten. I also have a Dell Inspiron 15 laptop running Windows 8.1, and when I connect to the TP-Link router with the laptop, I get full 18 MBPS net speed, at the exact same time that my PC is clicked on the SAME connection and getting 1 MBPS speed.

    So it's not the modem, router or range extender. It's something that happened during the Windows Ten install. Windows Ten isn't getting along with my TP-Link router and/or Linksys Range Extender.

    Here's what I've tried:
    -- Clicked to update my Adapter driver through Device Manager (it says I have the best one already)
    -- Downloaded and installed the newest Realtek Driver through Dell anyway, which says it's Windows 10 compatible.
    -- Unplugged and re-plugged my Range Extender to reset it.
    -- Chatted with Linksys Tech support. They say it has to be the adapter driver.
    -- Stopped all apps from running in the background.
    -- Stopped Microsoft from sharing my bandwidth.
    -- Unstalled BitDefender.
    -- Plus a few other fixes I found online that I can't recall just now.

    It's maddening because it HAS to be a simple, quick fix. I just don't know what it is.

    Yes, I could just connect to my CenturyLink modem signal and get full speed, but that signal is weak (which is why I got the Range Extender). I need that TP-Link connection for my full home network ... and 1 MBPS isn't going to fly.

    To me it looks like have updated Network adapter drivers on Dell since July 31 2015. I would install the latest and also looks like 2 types Intel Wifi and Realtek Ethernet. Correct system ? http://www.dell.com/support/home/us/...ivers/advanced

    Yep. I downloaded and installed the newer Realtek driver, dated Oct. 2015. Sadly, it did not resolve the problem.

    To correct my reply to you, jds63, the new driver was indeed dated July 2015, Version 10.1 etc...

    FYI, I ran a Windows diagnosis on my wireless connection, it found "a problem" with the network adapter and said it fixed the problem. But it did not solve the slow internet speed problem. So I ran it again, and it said it found a problem again, and it said it fixed the problem. Still no change in the slow internet.

    I printed out the long test and diagnosis readout, which I can post if anybody is qualified to understand it all.

    Meaning you are using Ethernet, not WiFi i saw also Intel WiFi there ? Since other systems work fine, resetting the modem will not help.

    No, I am only using wireless. The only wired connection (Ethernet) is between the modem and the router.

    Then looks like need the network adapter driver for WiFi listed on Dell as i believe Realtek was for Ethernet.
    Using any Optimization Software ? Have you installed all the Windows updates that are available
    Spyware and viruses can cause problems.Security software may also cause issues.

    Use this site to test https://www.speedtest.net/
    Is it all browsers or just one, or was your speed noticed by site like the one listed ?

    All browsers. Your speed test gave me just 1.75 MBPS, about the same as the speed tests I run on CNET and others. I'm paying for 20 MBPS, usually get 18 MBPS.

    When I switched to the CenturyLink modem connection, I got a fast 18.1 MBPS on your Ookla speed test, still using my Windows 10 PC.

    So it doesn't seem to be the browser. My desktop browser is Firefox. My laptop has Firefox and Explorer, and I get 18 MBPS on both wireless connections on that laptop, which is running Windows 8.1.
