This is an odd brand I've never dealt with before. My suggestion would be to take the back panel off and locate your wireless card (hopefully it's a card) and determine the actual manufacturer of the wireless solution. Then we can probably help you locate a suitable driver.
Sorry the computer brand and WiFi card brand are just very foreign to me, and I had no luck as well looking for a driver. For as cheap as WiFi cards are, maybe consider replacing it with one that is compatible with Windows 7?
I did find a datasheet for you card that only mentions Operating System support up to Vista-64. I'd say finding a replacement card would be much easier. Just make sure to get one that does Bluetooth as well, as it looks like your current card provides Bluetooth for your laptop (if you care about Bluetooth).
