I reinstalled my Lenovo Ideacentre K450 to factory. All went wwell 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 threre is no connection. I do not see any wireless network adapters in Device Manager. Any help appreciated.

Does the Wifi adapter appear in Device Manager after installing the chipset drivers? Are there any yellow exclamation marks next to any devices in Device Manager.

 

If after installing the chipset drivers no Wifi adapter is present in Device Manager it's possible the wifi card has failed. The chipset is a Realtek RTL8188EE according to this page. The chipset is not common and is not on Realtek's home page. It's looks like a chipset specifically made for OEM's, HP being one of the OEM's. You may want to pull the card and attach it again. Pull the power, hold the power button down for 30 seconds. Ground yourself on some bare metal of the case before attempting to pull the card.

 

You can either check the card by booting a live linux disk like Mint or purchase a USB Wifi dongle. Because it's a desktop you can purchase a dongle with antenna for better coverage.

Thanks for the reply, tried, did not work. No yellow exclamation marks.

Then I would either try the live linux disk which may require that you disable SecureBoot in your UEFI settings or try the USB dongle.
