Setting Up WLAN in Windows XP SP2 (Secured WPA2)

Pre-requisite:

  1. Wireless LAN adapter must support WPA2. Please refer to respective manufacturer.
  2. Prior to this setup attempt, user system has been known to be authenticated successfully with NTU domain via LAN network. A user profile is created automatically upon successful authentication via LAN.
  3. Windows XP SP2 native does not support WPA2. You need to download Update for Microsoft Windows XP (KB917021) from http://www.microsoft.com/downloads/details.aspx?FamilyID=2726f32f-d52b-4f84-ace8-f7fc20195769&DisplayLang=en  

    Restart the Windows XP after completing Microsoft Windows XP (KB917021) update.


Advantages:

  1. Wireless traffic is encrypted and is more secured compared to that of Open web-authentication (i.e. SSID: NTUWL). Strong encryption (AES) is used to ensure high data security in network traffic over the air.
  2. WPA2 has a stronger cipher than WPA and conforms to 802.11i standard. Therefore, WPA2 offers higher security and interoperability than WPA.
  3. User will need to login once to his/her system without the needs to re-enter credential to access Internet.
  4. User systems will be able to roam and join the NTU wireless network automatically whenever his/her systems are in the wireless coverage range without the hassle of manual re-login.
