Hello, I'll be buying an iMac in October and need to find an internet solution for me and my sister. Currently I use a PC, with a DSL modem which sends signals to my USB adapter attached to my PC. My sister, who owns a Macbook, who bought it one and a half years ago, has a long cable running underground from our modem to her Macbook in her room, as the USB device I use with my PC doesn't work on her Macbook. Once I buy my iMac, I'll need to find a way to access my internet connection, and I don't want to have a several meter cord running from our modem to my iMac. To try and solve this, I've been thinking about buying the Airport Extreme Base Station. Now I'm pretty sure if I connect this to my modem, it'll send signals to my iMac, right? (I've never used a router before.) The problem I have here though is it may work on my iMac, which is great, but I'm not sure if the router will send signals to my sister's Macbook, because I don't know if she has the settings required built in, like I will have with my iMac (which I was told numerous times). Is there anyway my sister can make the Airport Extreme Base Station send signals to her Macbook? May be a stupid question, I ain't so smart at these things. Thanks for taking the time to read this, Mikey.
