A Wireless network adapter has a wifi antenna that connects wirelessly to the router and an ethernet port that you connect to something that is non-wireless, thus connecting it wirelessly to the router.
I still don't get it - you have to plug the 360 in via ethernet? So what's wireless about it?
Not sure what you mean by a wireless bridge for non-wireless stuff. How does that work? My 360 is connected to my router by a discrete ethernet cable. Don't you need to buy a wireless adaptor to make any wireless stuff work on the 360?Basically, you plug the 360 via ethernet and it acts as a wireless adaptor
