I purchased a new NetGear MA401 Wireless PC Card for my son's laptop one month ago. Everything was up and running fine until he told me a couple days ago, it wouldn't connect to the internet. Everything I have checked seems fine, but the icon indicated "poor link quality 0%". I am sitting right next to the router! The system recognizes the card when I take it out and put it back in, but the light on it flashes, and it never find the connection. The driver is the most current. Any thoughts?
