anupbadri Actually the fix might be a lot simpler. I just chose the "Reset network connections" and when it restarted everything came up perfect. I have a ASRock A520M w/ a Ryzen 5 5600G. The settings for 10 seem to be different in 11, so before resetting your router and Wi-Fi (like I did first) just try the network setting reset.

    I upgraded from Windows 10 to Windows 11 a few weeks ago. Immediately my internet access slowed down considerably, so much it takes at least 60 seconds for a page to load. I have tried all the fixes above and my frustration is beginning to get the best of me. I had a fast, stable, Windows 10 system. In all the years I have used Windows this has to be the worst experience I have ever had. My desktop Dell is only 2 years old and I have a direct internet link with my hub for fast access..

    How can I get back to Windows 10 and get back my decent internet access speed.

      Have the same problem, installed windows 11 on a spare M.2 drive so have dual boot Winndows 11 and Windows 10 on the same PC. All settings for the RealTec ethernet nic are the same.

      Windows 10 gives 398Mbs over RealTec 2.5gb ethernet
      Windows 11 gives 79Mbs over RealTec 2.5gb ethernet

      Which leads me to conclude Windows 11 is still buggy after over a year from launch

      I had to separate 5GHz and 2.4GHz brother as individual networks and it's working again.

        It seems that my Internet speeds keep slowing down after a period of time and I have had to run SG TCP optimizer multiple times.  Based on the one suggestion, I have reset my network devices and now things are back to normal.  I just hope that the Internet speeds remain consistent and do not dip down again.  I also have Eero and do not have the option of separating the 5 GHZ and 2.4 GHZ bands.
