Hi Steve, not sure I understand the question so please bear with me. I have TWC with AE via Ethernet. New devices connect automatically. Nothing was required. I have XP and Win 7 as well as iDevices and Macs on the network. The only slight issue for me is the current version of Airport Utility for Mac does not support my vintage AE. I use an old Mac or PC to administer AE.
I downloaded Airport Utility from Apple's site on each PC.
Hope that helps. Don't worry if it doesn't. Someone who actually knows all about wireless networking will post soon.
Enjoy your new computer!
Thanks, Susan. Pretty much, I'm asking for the procedure for when one buys a new pc to replace an old one, with the intent of keeping all existing connections to a properly functioning aebs the same (and in my case, an express used to extend my network). All I want to do is swap out the computer and determine ahead of time what I need to do to connect my existing aebs to the new pc. Thanks!
Thanks again, sounds like the settings are saved onto the AEBS then, and when I plug it into the new PC via ethernet, all will be the same. Yes, I would def download the airport utility to be able to manage my settings going forward. I guess I just wanted to make sure nothing else was required (e.g. factory reset, start all over again as if I bought a new AEBS, etc.). thanks very much.
