I bought an airport express on ebay and set it up in my house to connect the printer in the office to the network. My airport express base station is 802.11g. But I'm going to build a Mac Mini media center around the base station and suppose that I should have the base station on 802.11n (it's faster, right?). So before I have to go out and buy a new 802.11n base station, I thought I'd try to figure out whether the airport express I got on ebay is "n" or "g." But I can't figure out how to get those specs on it. Thanks so much if you have a suggestion.
