My daughter is moving into an apartment that provides "free" wireless internet. The problem is that she has a 2009 Mac Pro tower that we've always used directly wired to the modem via an etherrnet cable. I have checked with the Apple retail store, and there is no Wifi card available to install nor any type of USB doggle that will work. I called the tech number for the apartments, and the adviser suggested I purchase an Airport Extreme, connect it to the Mac Pro via USB, and it would pick up the wifi signal. That sounds too simple, especially since no one Apple suggested that. The tower is running the latest version of OSX with 8GB or RAM. Can anyone confirm that the Extreme set-up as described above will solve this issue - or offer any other suggestions? Thanks. Wm.
