Over the holidays I got an iPod Touch and so far I’ve been really enjoying it. The one thing that annoyed me was the fact that so much of the iPod Touch’s stuff relies on wifi. My bedroom is a long way away from the wifi base station.
I really wanted to be able to use the internet on my iTouch so I did some Googling and found out about Internet Sharing – a really useful thing built into every mac.
Internet Sharing allows you to use the Internet from one interface (ie Ethernet) and transmit it out another interface (ie wifi).
What you do is you go into System Preferences >> Sharing. If you go into the Internet sharing options you can set out up.
First, you set where you want to get your Internet from and then you can set the interface(s) that you want to broardcast your connection. The interfaces that you can transmit out on are Airport, Ethernet, Bluetooth PAN and FireWire.
For the transmitting over Airport, you actually create your own network that your Mac broadcasts. You also have some extra settings that you can use. You can give your network a name, password, set which band to use etc.
The way that I have it set up is that I have my MacBook transmitting a wireless network using my Macs Ethernet connection. The network is called iPod Touch and I have a password set up.
I find internet sharing really useful and it means that I can acctually use my iPod touch. If you are having troubbles with poor wifi signal in your home or office, before you go out and buy a booster take a look at Internet Sharing.
