unable to connect using wireless connection

Since successfully restoring my laptop to factory settings I have been unable to connect using my Intel PRO/Wireless 3945ABG Network Connection.

Initially it worked, but after a while it stopped. I have completed several system restores, and the wireless connection works for a few days. On the last occasion (after installing windows updates) I received the dreaded blue screen and have been unable to connect.

On Saturday, my wireless connection suddenly starting working, 24 hours later it stopped.

I am not sure if it is related to installing new windows updates as prior to restoring to factory settings I had no issues with my wireless connection.

I am able to connect using the ethernet cable and I am currently able to connect using Pluscom wireless usb adapter.

I would be grateful for any suggestions as its driving my insane.
