Hi all, I am trying to set up our airport extreme with our new service. We had comcast before, and have comcast now. We have a macbook and a mbp The modem they sent me is working, I can connect it to our macbook directly. The modem into the airport extreme, then connect by ethernet to the macbook works fine. So to my knowledge, the airport extreme is working? I set the airport extreme up with the same password as before. Both the macbook and mbp see the signal, and there is a green light on the airport extreme, however neither computer can connect to the wireless signal (even when I am sitting right in front of it with a computer). Any ideas on what the problem may be? The mbp can not read the ethernet line from the airport express (which I think is totally weird since the macbook can). I thought I had everything set up the same, but clearly something is different.... Any help would be appreciated!
