Unfortunately, Mountain Lion does not officially support your older version of the AirPort Express.
Some users have had success by using a special utility to create an "unofficial" installation of the product on Mountain Lion.
See this article for more details:
It works fine for me, but I cannot say whether it will work for you.
Thanks for your reply and the link to try. I will see it that works, otherwise I will have to buy a new one (& probably a new base station as well since they r both at least 4-5 years old). Ugg.
How do you feel about the TimeMachine/TimeCapsule one?(if you know anything about it that is) or do you think it is a waste of money? I'm not that savy when it comes to this stuff and the guys at the apple store talk to me in all of these words that is like a language from Mars or something, ha, and then when I ask them to just tell me what to get that is going to be EASY for ME to set up they say that can't really give me a specific item because "it all depends on what I'm doing!" AHHHH, it make me want to scream because all I want to do is go on the Internet, have my pictures backed up automatically (I've had TWO Apple hard drives completely crash on me & then I lost thousands of pictures from over the years because NO ONE told me I should be backing up my laptops to an external hard drive) work in iPhoto, iWork, etc. VERY basic stuff! I'm not a "Gamer" as they say so I don't really care about all the amazing color graphics, etc. I just want to be able to sync my iPhone, iPad 4, and my MacBook Pro (which I'm returning & getting the NEW iMac Desktop if it ever comes out!) all seamlessly and automatically backed up.
Thank you for taking the time to respond to my question earlier and if you have any thoughts or opinions on what I should purchase/get to make my technological life easier, that would be Absolutely AMAZING!!
