i have installed the drivers successfully, and the computer recognizes the device. i am running windows 7-64 bit. the problem is i cant get a steady connection with the internet. bounces back and fourth from connected to cable unpluged. the ethernet cable is good, have tried it on multiple computers. is it a software or hardware problem?

also i cant get a steady green light on the adaptor
