Windows 10 Update - Wifi speed now limited

Anonymous

Hello there,

I have installed "Version 1809 OS Build 17763.316" recently, and have had wifi speed issues ever since on Windows 10. My wife's macbook is fine, and our cellphones are unaffected by the speed decrease.

I have ran about 30 speed tests today, and I seem to be capped at 5mbps. Three of those times I somehow went up to just under 10mbps. My download speed should be 50mbps.

I have tried both 5ghz and 2.4ghz.

I have tried both my wireless dongle and the built in wireless adapter.

I have updated all the drivers.

I uninstalled and re-downloaded the drivers.

I have restarted my router multiple times.

I did a factory reset of the router.

I did a network troubleshoot, which found nothing.

I did a disk cleanup.

I looked through many similar (older) issues with wifi speed and none of the solutions have worked for me so far. I found this issue a few pages back for a wired connection (also limiting to 5mbps), but his issue was resolved with a simple router reset. So far, this has not been the case for me.

Any insight into this would be great.

    Hi ChrisHass,

    I'm glad you solved it.

    If you had already specified what was the model of your PC, I would have immediately suggested to uninstall SmartByte.

    From Google source:

    "SmartByte developed by Rivet Networks, the company behind the powerful Killer Networking Wi-Fi cards that appear in several Dell and Alienware laptops, SmartByte automatically detects when you're streaming video."

    And Dell:

    NEVERMIND! This has been resolved.

    Franco, I saw another post where you recommended temporarily uninstalling SmartByte. It worked....

    How and why this is affecting wifi speeds all of a sudden is beyond me. But thank you, everybody.

    Hey Franco,

    The computer is a desktop, a Dell Inspiron 3650.

    The built in adapter is "Qualcomm QCA9565 802.11b/g/n Wireless Adapter". Its a 2.4ghz PCIe adapter that comes stock with the computer.

    My wifi dongle I prefer to use is 5ghz, and its a "Realtek 8812AU Wireless LAN 802.11ac USB NIC".

    Again, both drivers are up to date. Both were uninstalled and reinstalled. The speeds I'm getting are the same regardless of the wifi adapter I'm using.

    I'm still getting the good ol' 10mbps upload, though.

    I'll reset everything as a last option this weekend if I cannot figure a better option out by that time.

    Hi Chris, I'm Graeme, an independent adviser here to help.

    From the list of troubleshooting steps you've already tried, there isn't much else that I could recommend as the cause of the issue. Factory resetting the router and reinstalling the network drivers would usually resolve the issue if it's a Windows 10 problem.

    The only two other options I can suggest would be to contact your internet service provider for further troubleshooting support, or to try resetting your PC if you're willing to try that. A reset often fixes issues like this, and if the reset doesn't, then you'll know it's probably a hardware issue, perhaps a faulty network adapter on your PC.

    If you choose to, you can reset your PC just by searching for Reset in Start, and following the prompts. You can keep your files, but you'll need to reinstall your apps.

    Please let me know if you need further support! Thanks!

    Hi ChrisHass,

    Please specify the manufacturer and model of your PC and whether it is a desktop PC or laptop. Also specify the exact model of your wi-fi adapter.
