I purchased an eMac off of Craigslist and didn't know the model. It turns out it is the original model that will only work with the original AirPort card. My network currently has 3 5th Gen AirPort Extreme base-stations and is running on the 5 GHz band. Do I need to get an original AirPort base-station to run this eMac, or do I just need to turn on the 2.4 GHz band?

Thanks.
