I would like to connect my DirecTV satellite box to the internet using my household wifi. This would allow me to program the box remotely and download movies late at night. A wireless ether-net adapter (won't accept usb) will cost about $100, which I'd rather not spend. It's on another floor so wiring would be a real hassle. I have an old, but functioning, 802.11b wireless router. How do I set it up to behave like a wireless adapter so it would connect to my main wireless router (802.11b/g)?
