Hi, My idea is to buy a usb air card and plug it into my desktop along with the cat5 network cable which provides network and Internet service from the company. When I want to get on the web for personal use I'll switch to the air card, and when I want to access the network or Internet for office use I'll use the network connection. Can this be done? How do I set it up in windows 7? I'm a novice so please be as explicit and complete as possible. Thank you very much for your time and consideration.
