This post will show you how to solve the Wifi issues that you are experiencing. If you want to fix these problems and ensure that your system works at its optimal levels every time, then you need to be able to restore your settings.
If you want to fix Wifi Disconnects in windows is to download a driver for your Wifi device and then install it. Now that you have the drivers, you can then install the Wifi driver on your PC and get your wireless network running properly again.
Sometimes, you will not be able to get into Wifi, for example when you are using an Airport router. If you have one of these wireless devices, and you don't have another wireless device plugged into the back of the Airport router, then it might be due to something else. You can then try resetting your Wifi to see if this improves things.
