I have a DSL modem at home, which is connected to my phone line (where the service comes in from) and which then goes out to my iMac through a Ethernet wire. I needed to buy a router now so that I can share my internet connection with both my iMac and the MacBook, namely because the Internet Sharing option is so slow when sharing through Airport. I was looking at the Airport Extreme, but I noticed that there's nowhere to put the incoming phone cord, which is where I get my service from. There's Ethernet ports, but wouldn't I need to connect the phone line to the Airport Extreme in order to send out the signal? Or am I just erasing the DSL Modem from the equation when it needs to be there? I can see connecting the Ethernet from the DSL modem to the Airport Express and then using that to broadcast the internet signal? Sorry for the confussion.
