    Hi,

    I have a MacBookPro that I use in my room connected through ethernet. I am at university and they have only allow one machine to connect to their wi-fi that is available across campus, through mac address filtering. I also have an iPhone which I would love to use wi-fi on, at least while I am in my room lounging around and such.

    Anyway, the point being, can I use my MBP (connected through LAN) to act as a router so that my iPhone can connect to it? Essentially create a wireless network, so iPhone would find it and I could go online on it via wi-fi?

    I tried going on Airport and clicking on "Create a network" (w/o a password), but I get an error saying "There was an error creating our Computer-to-Computer network.". It doesn't say much else -- is there a better way of doing this?

    Many Thanks,

    Simple solution.
    Assuming you are on leopard.
    Go to sharing in system preferences and enable internet sharing.
    If your mac is connected via ethernet then you can set up the airport to allow other machines to "share" the connection.
    make sure you use a password though under airport options.
    Hope this helps

    many thanks -- that worked brilliantly!

    one more question -- When I set up a "router" through my macbook in this fashion, can only other Mac's connect to it? Or can I also have a Windows laptop that can connect to it? I see one of the options on the sharing mentioning "Airport" as the source to connect.

    My iPhone connected to it nicely, but i wasn't able to connect a windows laptop to it.. any ideas?

    Thanks,

    "Airport" is just Apple's name for 802.11 wifi. Any standard wifi device can connect to it (I've done so with various non-Apple products).

    As the previous poster mentioned, you should be able to connect any compatible wireless device.
    Make sure you are using the same type if WEP encryption on both devices.

    You could also group together with neighbours and buy an Airport Express, allowing them access to Wifi etc.

    Were you trying to connect both the laptop and the iPhone at the same time? That isn't possible. Your MBP can only accept 1 (one) connection at a time, so it's either your other laptop or your iPhone, but not both simultaneously.

    Well I'd like to point the fact that even when you use WEP, your wifi network will be unsecure. WEP is known as weak an can be hacked in some seconds.

    Yes..Be your own wifi hub

    Yes, you can, I connect to the internet using my cell phone as a modem, (legally, through my cell company), on my G4, tiger, I then share my connection with internet sharing with my husband, (on a PC) or anyone else who happens by.

    I second the router suggestion. A cheap router offers better security and your MBP does not have to be on for you to get WiFi. Not to mention now you can sit on your bed (or wherever) and get internet. You can just clone the MAC from your MBP to the router. Colleges usually dont care that you have a WiFi network as long as it is for personal use.

    Most routers have this function.

    I have read most of the post but still unable to do it. Could some one help me please?

    I have a MBP running on leopard.
    So far I have enabled the internet sharing and checked the airport box.
    Like so:
    [​IMG]

    I went to network to set up a new connection name "Bacon". But when I try to connect to my "Bacon" network using my iPhone, it doesn't work. All it says is
    "airport has a self assigned IP address and may not be able to connect to the internet", like so:
    [​IMG]

    Could someone help me please? I don't know what I have done wrong.
