I am considering buying it, but have some doubts and questions about it. 1- I currently have ADSL internet, but the wireless router I have right now is pathetic. Would I be able to use the AirPort Extreme as my new router (connect the internet cable directly to it)? Or would I need to bridge them? 2- It says it has an incredible range, but how much distance does it covers? All the walls in my house are made from concrete, not sure if this makes the signal weaker. 3- I have a Core Duo MB, so I don't have the new "n" technology, would it still be worth it? I want to be able to use it to back-up, but I don't want it to be painfully slow. Any other recommendations would be greatly appreciated. Thanks, Roco.
