Using airport as a wireless transmitter

[SirSquishie]

I just bought my first iMac a little while ago, and I've seen it used as a wireless network transmitter to give another iMac access to the internet without being plugged into any kind of modem.

My question is how is this done?

And could it be used to allow my Wii to connect to the internet without buying a $30 adapter to plug it in?

It is called internet sharing. It is in your Sharing Preference Pane, in the Internet tab. Just select from Built-in Ethernet to AirPort and you should be ready to go, just set the connecting computer to use DHCP and connect to your new ad-hoc wireless network.

As for using it for your Wii, I'm not sure. I tried using it on my 1st Gen AirPort with my DS buy I didn't send the 2Mb/s signal only the 11Mb/s. I'm not sure if the Wii uses the full 11Mb signal or require the 2Mb signal. Your best bet would be to actually buy an AirPort Express to supply wireless signal to both your computer and the Wii (and it is only twice the cost of the LAN dongle for the Wii).
