Either router should play well with your FairPoint DSL. The Netgear has all the bells and whistles of a dual band router with GB switch if you need the capacity. Personally running a Netgear DGN2200 and it handles a Roku and an OBI110 running Voip.ms and GoogleVoice with no problem whatsoever. Either the X2000 or DGN3700 is a huge upgrade over the Westell FP provided.
I am currently using a verizon westell 6100 so I'm sure any newer modem would be better. I like all the bells & whistles that the DGND3700 offers, but it might be a bit overkill, and X2000 seems like a good choice, if the X3000 was available I'd probably grab one but not available in NA yet. Thanks for your reply BY
