Laptop: MSI GS65 Stealth-006
- Intel(r) Wireless-AC 9560​
- Driver version: 21.50.1.1​

Modem: Spectrum DOCSIS 3.1 eMTA

Router: Spectrum Wave 2 - RAC2V1S Sagemcom

ISP: Spectrum @ 400 Mbps

OS: Windows 10 Home - Version 1909

My Issue:

Over the last couple of days, my download speeds on my laptop have been pitiful at best (1 - 3 MBps) compared to what they were before (50+ MBps). I can't pinpoint exactly when this started nor can I tell what caused it specifically, I just remember one thing in specific was updating to Windows 10 1909 from 1809, but I don't see how or why that would cause this issue, and I am also unable to go back to the old version of Windows as I no longer have the old.Windows files. I have looked over dozens of forum posts for slow internet and tried many different "fixes" only for none of them to make a difference. I have made sure that my drivers are up to date and have uninstalled, reinstalled, disabled, re-enabled, changed settings, changed them back; You name it, I have probably done it yet nothing has changed. I have removed every device from my wifi network except for my laptop that is having the issue and my cell phone, which is a Samsung Galaxy Note 8.

One thing that is peculiar is that speedtest.net shows that I get roughly 130 Mbps down when I run it on the computer, yet Steam is the only application that seems to be able to take advantage of this full speed (that was before capturing the screenshot, now Steam seems to be downloading greater than what my speedtest shows) whereas everything else I have tried has not been able to (Origin, Firefox), being stuck at the 1 - 3 MBps from before. When I run the speed test from my phone, I get around 350+ Mbps which isn't as high as it should be, but it is still closer to normal compared to my laptop. Both devices are connected over 5ghz wifi and have had flawless signal and connection up until now. I live in a small studio apartment and my laptop is generally right next to the router with no obstructions in the way so I know that the signal is not the issue. Another odd thing is that when looking at the adapter's Wi-Fi Status page in Windows, it shows my connection speed at 866.7 Mbps which is much higher than what I am getting, but this value may be irrelevant, I just don't know.

Any help on this would be very appreciated as I have already contacted my ISP and had someone come out and although they replaced some old cable and wall connectors, it hasn't made a difference and I don't know what else to do. I am unfamiliar with post styling and format, so you can find pictures of everything that I have bolded at the end of the post. Thanks in advance for looking this over and any help that you all may give.

On your laptops network card properties, do you specify a DNS address? If not try to input googles dns which is 8.8.8.8 and 8.8.4.4 and see if your speed improves.

This was something I figured wasn't an issue because my phone which is using my ISP's dns is connecting just fine, but I went ahead and tried it anyways and flushed the dns and if anything it was just a little slower, so no dice.

I have a Dell G5 5590 and here I am being all I would make my laptop run a whole lot better with newer drivers and I checked some latest driver versions on the Dell website and I stumbled upon a new driver version for my Intel Wireless-AC 9560 which is the version 21.50.1.1. After I installed it, I noticed my download speed decreased from 5-6 mbps to 2-3 mbps on steam download. My internet speed is 50 mbps btw.

So anyway I checked with speedtests and really saw the decrease of download speed by at least 50%. After hours of pondering what can be the culprit, I checked other forums and saw smartbyte being the problem frequently and so I did removed it and saw no improvements. Then I realized that my connection heavily relies to the wireless drivers and so I rolled back the driver version from the device manager and my download speed returned to its normal peak performance!

The lesson for me here is don't fix it if it ain't broken"!:LOL::LOL:

By the way, my previous version before the 21.50.1.1 was 21.20.1.1.

So yeah, the version 21.50.1.1 is the problem!
