WIN 10 Creators Upgrade drops my internet speed dramatically

Running Win 10..got pop up saying I needed an upgrade..which took place...after this my internet speed dropped from around 75Mbps to around 1Mbp!..If I roll back to previous version of Win 10 the speed is back...I have had 3 lengthy support calls with microsoft whereby they remote accessed my p.c. and updated drivers etc...but to no avail...I know I have the latest drivers installed now but still if I allow the upgrade to take place my internet speed drops to a crawl..so I continue to roll back to earlier version.I have disabled the upgrade from taking place for now..however I would much prefer to have the upgrade in place...any suggestions? Thanks

Have you tried previous version of the network card driver.

Thanks for the reply...yes..one of the first things I did try..no joy

Looks like your computer network card is not compatible with latest version of Windows 10.
You can wait and hope new version of the network card driver will be released soon and maybe resolves the issue.

I was starting to think that way....D Link DWA 171...Windows says best driver already installed..I will look further into it..many thanks for your suggestion.

You are very welcome!

I have the same exact problem. I'm on Verizon Fios and my wireless download speed dropped to 1.7-2 after the update. I think it's the new stricter driver restrictions in the uipdate. (Speed improved after I switched to Google dns service but that is a different issue). Something happened to the graphic video drivers as well as the wireless adapter drivers and who knows what else. They worked fine before the update but both are messed up since then and I cannot update the drivers because W10 refuses to install newer drivers saying they are not certified for my pc (probably because my laptop originally came with W8.1 and was ugraded to W10).

How did you roll back the update? I want to do the same.

Settings...update & security...recovery..revert back to earlier version (if you haven`t waited too long)..then delete the Windows update folder from your pc or it will continue to upgrade time after time!

Thank you. Unfortunately I waited too long.

Just had another Windows update today. I'll see how it does and if it does not help I may restore an earlier image backup.
