    I'm moving to uni in about a month, and there is no wifi there, only an ethernet cable in my room.

    My question is - can i plug the ethernet cable into my macbook and broadcast a wireless network from it? I know you can make a wireless network on a macbook, i've done it before, but i want to broadcast the internet over it. I want to be able to use my iPhone on wifi, cos I don't wanna go over my allowance (damn o2).

    Thank you for any help.

    I don't get it, yes it will work as Hellhammer advised, however Ad-Hoc wireless doesn't have the greatest of ranges so you're more likely to be getting it in the same room the MacBook's in, so why not just use that for surfing instead of the phone?

    Internet sharing works fine, I use it when I'm working abroad to share my wireless usb modem to my iPhone.

    As you will at Uni for some time, I would advise that you just get a wireless access point like this one , it's only 20 quid and will save you having to have your macbook on all the time to use your iPhone. Internet sharing also drains your battery faster.

    Also your macbook will work off this wirelessly so it's a win-win!

    I wanted to facetime with my family while i'm away. It's only a small room, so range doesn't matter massively.

    To add.

    You might want to take a look at an Airport Express. Connect to the Ethernet cable and it provides a WiFi hotspot.

    It also provides the following convenient functions:
    - USB port for a printer
    - Audio port out for your stereo
