Sorry if this has been asked before, but I have been looking for a while and I didn't find any information. I have a dual band airport extreme that I use as my main wireless point for my 2 n-enabled macbooks pro and I got and old emac hookup by Ethernet cable to the same base station (everything on the second floor of my house) , and I'm trying to connect an old airport extreme "UFO" to my xbox (first floor of my house). Can I extend my "g" network if so, how do i do it (I need step by step help)???how do i recognize the old base station??what will happened with the speed on the house??will it be affected??? Thanks.
