Hello, Please pardon my noobishness.. I have just bought an Airport Extreme assuming it is a wireless modem like my old Netgear DG834G.. I have tried plugging in the cable that comes from my telephone line into the internet WAN port with no recognition from the Airport Extreme.. Am I correct to say that the Airport Extreme is NOT a modem like the DG834 or is it? Will it mean I need an external modem to connect me to the internet? Right now its working flawlessly with the WAN port connected to an ethernet port to the DG834.. It's freaking fast! Reno.
