I am planning to strengthen my WiFi security from WPA to WPA2.
Here's what I have: . Notebook PC (WinXP Home SP2) with Intel 2200BG WiFi card . Desktop PC (WinXP Pro SP2) with Linksys WUSB54G USB WiFi card . Linksys WiFi access point/router WRT54G v3 with latest firmware (supports WPA2)
Notebook Intel WiFi driver GUI shows an option to configure WPA2 Personal or Enterprise. Desktop Linksys WiFi driver GUI does not show any option to configure WPA2 Personal/Enterprise (it only shows WPA Personal/Enterprise configuration options). On both computers, I am using the vendor's WiFi graphical interface instead of Windows WZC.
If understand correctly, to get WPA (not WPA2) to work, the following condition must be true (feel free to correct me if I'm wrong):
- WiFi card and WiFi access point must support WPA encryption
- OS must support it too (WinXP SP2 later versions support WPA but older versions do not)
and here's what I am not sure about:
- Is WPA2 encryption OS related or WiFi driver related?
- Does WinXP SP2 need KB893357
- Will it work fine without KB893357 patch if WiFi driver already supports WPA2 (for example, my notebook PC WiFi)?
Hope I explain that clearly. Anyone?
