Why does Wireless Connections drop when using a secured network?


This issue has been bothering me for awhile now.
My wireless NIC, Intel Pro 3945 ABG, is able to scan networks and connect to them.

It can maintain a stable connection when the network is unsecured. I can browse the internet for days without losing connection.
However, the connection to a secured network, WEP/WPA/WPA2, will drop within the first 1~2 minutes of accessing the internet. I can reconnect almost immediately after the connection drop, but it would repeat itself within 1~2 minutes.

It has been tested on both the drivers Toshiba provided and the latest Intel drivers, and I was able to reproduce the same results.

Can an expert point me in the right direction?

Forgot to mention, I am on Vista 32bit Enterprise.

Thanks in advance.
