    So i was searching through the posts about the Airport express as i was hoping to get wi-fi for my room so i could use it for my iPhone. When i went to the store they said i could use the express to plug into the wall ethernet jack and it would create the wi-fi from my wired internet modem downstairs.

    But my brother has a new imac less then 50 feet from my room...can that create a wi-fi signal if its plugged into the wall? I didn't really understand what was going on when i read this in another thread so many someone can tell me if i can save some cash and just have the iMac run the wi-fi or if i its smarter to get the express if i want continuous wi-fi in my room.

    I dunno if having the iMac create the wi-fi means you can't you use it? etc...
    Just concerns i need addressed. Thanks

    Go to System Preferences- Sharing- Internet (tab)- and set this up using the Airport option. This will create a network using your iMac as the router (origin of the signal).
