recently I updated my windows 10 to windows 11. after that my download speed is suddenly decreased my actual internet speed is 25mbps when I check on the speed test also its showing 25mbps but while downloading on chrome or on Microsoft edge it'll be decreased to around 200kbps and even youtube is also the same. I tried resetting the network adapter. please give me some solution.

I ran TCP Optimizer, I got some errors about not having admin rights, but even still my speed improved dramatically. Here's hoping it sticks.

Have you found a resolution yet? I have the same issue (occurs both over wired and wireless connections). If I reinstall NIC drivers, speed is restored, but by the next day it has dropped from 170 Mbps to only 10. Each time I reinstall the NIC driver, the internet speed is restored but never lasts.

@anupbadri Trıed all solution in this entry. Finally find it. If you ever faced with same issue and could not fixed it I hope this will work. I just turned off Bluetooth. And now it works like charm.

@bryandav1965 This was a huge help. Same story as a lot of folks, upgraded from 10 to 11, have 1 Gig internet, was only getting around 30 m down. Used TCP Optimizer, got my speeds back. Annoying bug for sure. Appreciate your insight

Well, did a clean install of Windows 11 and my speeds dramatically improved to over 200 Mbps. But the slowdown reoccurs requiring me to go into device manager, delete the NIC driver, and reinstalling it. I've gotten it down to a science now and it only takes a few seconds but its still a pain in the arse. Microsoft needs to fix this.

What works for me was disabling "Network" optimization from Dell Optimizer tools.
I have a Dell Precision with WIndows 11.
I had a drop in connection everytime I would open Microsoft Teams, and it will persist even if I close the app or the web tab (from 400 Mbps to 0.5Mbps).
I tried everything from :
- updating drivers
- updating dock driver (USB connection to my laptop)
- disabling IPV6
- trying with and without AWS VPN
- tried the web app instead of desktop app for Teams
- Windows Update
- Dell Command Update
- Office 325 Update
- trying Wifi 2.4 and 5GHz
- trying direct Ethernet connection from router
Found out there were artificial intelligence from Dell on the network that was "Give maximum bandwith to the conference app I'm using". I disabled the option and my connection was normal again.

Hello, I'm also having Internet download speeds issues on Windows 11, but in my case this is related to USB3 ethernet adapters, when I use WiFi it works great every time.
Here is more https://superuser.com/questions/1729035/slower-internet-speeds-with-usb-ethernet-adapter-than-card-f... this is driving me nuts... I checked everything I have idea.

@svhelden in my case it does not matter if I have plugged supply or change device power plan, this happen even if I have all set into performance mode. This issue is 100% related to Windows 11 or USB ethernet cards drivers ( funny that with chipsets from Realtek and ASIX is the same problem ). If I run test with Linux USB bootable speeds are awesome with that USB cards... easy & stable over 40-50 MB/s from Internet, normally it starts around 15 MB/s and drops to 4-5 MB/s.
