im not too technically gifted, but i was hoping i could get some clarification. is it possible to use the time capsule (or air port extreme really) as a wireless router without a modem. by this i mean do you just plug in the phone line direct to the device and then go or do you HAVE to add you own modem. the apple website says you need to plug in your modem to time capsule to make it work, but it didnt elaborate. any comments would be much appreciated.
