Error or Problem: WEV_EXCLUDE_LIST_REASON_802_11_AUTH_FAILURE
Wireless Card/Adapter: Intel Centrino Wireless-N1030, 1x2 bgn (2.4GHz) + Bluetooth
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.
I've seen a few people posting with issues about older Intel drivers lately. Intel came out with a new version of most of their drivers, including one for the N1030.
You didn't list whether your Win7 is 32-bit or 64-bit versions but here is a link to the driver downloads for the Intel N1030 card. You can select the correct version you need and download / install.
A lot of people have seen various issues resolved by updating to the newer 17.xx version of the drivers for their Intel cards. Try it and see if it helps you.
Let us know how it goes.
