Apple has a range of wireless networking options going under the Air Port moniker, and the Air Port Express Base Station is the entry-level model. Air Port models compared It's an interesting device.It had a refresh last year and in terms of styling now looks somewhat like a white Apple TV.
One thing that you need to note is that the Air Port Express Base Station, as with its larger brethren the Air Port Extreme and Time Capsule, doesn't act as a modem.
So you can't use it to replace a dial-up broadband router (the type that typically provides your internet).
So you need to connect the Air Port Express Base Station to your current router, which these days is probably already providing you with a wireless connection.
