wev_exclude_list_reason_802_11_auth_failure error on Wireless or WiFi Window7 inspiron 14z n411z

Wireless Card/Adapter: Intel Centrino Wireless-N1030, 1x2 bgn (2.4GHz) + Bluetooth

Microsoft Window7

It has taken me long hours and days to find a workaround for this problem.  There are only few citations for this type of error or problem on the INTERNET.

This  problem has been tested to repeat when I connect to multiple WiFi Access Points / Wireless Routers.  Hence it is not an isolated case to a single router or model.

Possible reasons:

• The driver does not support WPA2 wireless encryption

Workaround:

1. I have changed the wireless security setting on the router to WPA from WPA2 (AES/TKIP)
2. Then this error disappears

Question:

1. Why doesn't the driver support WPA2?  If it does, why does this error occur.
2. How can one use WPA2 on this driver and hardware.  Since WPA2 is superior and more secure than WPA.
