What must have a base station for Internet access with a MacBook or can you just use a wifi hub?
I'll get a MacBook, or has and wifi hub but something told me it needs a base station, right? My other question is how a MacBook come with 'Airport' or you have to buy / download (specify which) thank you very much
Most come with a MacBook AirPort wireless card already in them. Just check if it was acquired. A Mac is connected to any wireless network, so if you have a wireless network that is working for your PC, Mac access it without any problem. A base station (airport) is what you need to connect your modem to a wireless network if you do not already have one.
