Thanks!
I contacted Sager the other day (3rd time was a charm, and begging helped) and they told me to download the 4760 drivers. Which funny enough was the same USB300 driver I had at the beginning of all this. What I didn't realize is that I have to configure the driver down to a T! From channel, Wep Key, infrastructure, SSID all manually. Once I did that it has worked ever since. Never had to do that before, except obviously the WEP Key. At any rate, I am good to go finally.
