i have an airport extreme and I'm trying to install the software for it onto my new iMac. When i plug the adapter into the wall, there aren't any colored lights (amber and green), only white, so i think i have an old airport. so is the software still compatible? what's going on? my internet provider currently is wild-blue and i have a satellite that send the internet to the modem connected to my desktop computer. so do i plug the ethernet cable from the modem to the airport? or from the airport to my desktop. i want to get wireless internet onto my MacBook Pro laptop.
