I reinstalled my Lenovo Ideacentre K450 to factory, Win 8. All went well except I was not getting a wireless network connection, went to Device Manage and saw a program "wan miniport (network adapter) was onop. Tried updating the driver,no good, googled the problem and was told to uninstall it (by 3 different sources), then to click on the Computer name and click changes made and I did so, still no wireless connection. I am using my network adapter to connect, without it there is no connection. I do not see any wireless network adapters in Device Manager. Any help appreciated.
