My Airport Express stopped working after I did my software update for my Airport EXTREME the other day. It lost the connection to my Airport EXPRESS and so I did a hard reset and tried to redo the whole profile but after many, many hard resets, I still can't make it work. Airport Setup Assistant shows that the setup is complete and everything is fine. But if I select "Extend my wireless range", after the setup, my Airport Express won't even appear anywhere. If I select "Join my wireless network" then it will appear with a 169.xxx.xxx.xxx IP address under my Airport Utility. It will also show up on my iTunes but I can't open it using Airport Utility and iTunes spends a long time searching for it and then gives up. In all the above cases, the amber light remains flashing and the green light never comes on. What else can I do to fix this??
