This causes the speed to significantly decrease as only some of the data is getting sent/received and has to be sent/received again until it get through to the host or server. The wireless card's drivers installed with windows 10 were actually an older version number than any of the current windows 8.1 drivers.Įssentially what was happening to me was the wireless was dropping data packets over and over. For me it turned out to be a driver issue.

I had an issue with slow wifi on one of my laptops. So it might work to update it first then install windows 10?

But you can't delete the old one because the version for windows that you are running isn't compatible with it so you end up getting a loop of error messages say you can't install this until you uninstall this one and then you can't uninstall this one because you're using the wrong version of windows and repeat. They do have a killer network manager update on their website but you can't install it on windows 10 without deleting the old one first.

I think I'll wait a few months to try windows 10 again.Īlso, from my searching today the wifi bug seem to be effecting most dell computers with the killer network manager. So I went back to 8.1 and all is well again with my wifi. It kept timing out and there was really nothing I could do. Well I tried that and it all when to plan until it wouldn't install the driver. I read on another forum where people were having the same problem to uninstall the network card and then restart and then it will auto detect the network card when you start up and then you reinstall the driver.
