WPA wireless authentication in Windows 8.1

0) Go to command line, preferably Administrator.

1) C:\Windows\System32> cd \Users\<User>\Documents

2) C:\Users\<User>\Documents> netsh

3) netsh> wlan

4) netsh wlan> show profiles

5) delete profile name='TIST'

Dont close window

6) Right click the connection icon in lower right corner > open Network and Sharing Center > Set up a new connection or network > Manually connect to a wireless network

7) Try to create a profile, and try to get as many details to correspond with your requirement. The rest we'll edit in command line, so let's make it as easy as possible.

8) Do the same at the next screen. Edit Network settings > change all the parameters that you can, to match the requirement. My university tech support has a detailed document listing the options to choose, usually for windows 7, or even windows 8. get as many of them as possible.

9) Finish. Move back to your netsh terminal
10) netsh wlan> show profile TIST

netsh wlan> set profileparameter name=TIST authentication=wpa 

netsh wlan> set profileparameter name=TIST encryption=TKIP

netsh wlan> set profileparameter name=TIST authMode=PEAP
