We were surprised when we saw that Windows 8.1 seems removed the capability of connect to a wireless network secured with WPA/TKIP Enterprise.

This post will explain you how to connect your windows 8.1 laptop to a WPA/TKIP Enterprise wireless network and how to export the profile (to be able to import it later).

Before starting

Microsoft removed the capability to set up the WPA security wireless and its associated types of encryption (c.-TKIP). While most companies have switched to WPA2 or better, there are still many companies still using WPA/TKIP Enterprise.

Even if Microsoft removed this feature from the wireless configuration interface, they apparently did not remove that capability from the operating system.

Here are step-by-step instructions on how to get your computer or other device running Windows 8.1 to connect to a wireless network running WPA/TKIP Enterprise.
