Does the airport capability mean that you can use your apple macbook to normally browse websites in any room at your home. Net speed is actually as fast as if connected with ethernet cable ??
Example: your "airport modem" can be in different room(connected to net cable) all the time and you can download files with the macbook from another room fully wirelessly?(until battery runs out of course)
So the files move in the air LOL??
Yes. You can browse from anywhere in the house, provided the signal strenght is good enough. Distance, walls, and other wireless networks can degrade signal strength.
As for speed, I (for example) have a 4Mbs Cable Modem connection. This is piped into a wireless router. I am at the other end of the house and upstairs. The wireless network is running at 54mbs. Thus it is the speed of the internet connection that is the limiting factor (actually, it is the speed of the server you are accessing that is often the limitiing factor once you get a fast connection).
With three computers on the wireless network (more are possible - but the cable contract says three is the limit), all of them can use the internet connection at the same time. However, the bandwidth will be used by all connected machines and can cause a bit of a slow-down. Only an issue if you are streaming lots of media over the web.
Last year I was using a 804b router. Even that was faster then the 4mbs internet connection. The new 804n routers are masive overkill unless you want to be running something like an Apple TV and surf at the same time...
Of course you don't need a router or even an internet connection if you neighbour has not secured his network
Note - Always secure your home network. Change the default admin password of your router! Use encryption! Set up a list of trusted MAC addresses! Say no to free-loaders
