"I'm happy with this Modem."5.0 starson by mburnstein
Pros: I'm not very technically oriented. I saw a significant speed increase over my 6 year old Linksys modem/router.
Cons: I could not make it work with Apple's Airport Express. Even after finding many posts detailing the "fix" I still could not do it. But I bought a Netgear router to go with it and the system is purring now.
Summary: I bought a new Macbook pro (9/2012). When I did my Internet access slowed noticeably. I figured the newer technology in the Macbook must not like the older technology in my modem. The new modem arrived -- I called Comcast and in about 10 minutes they had it set up. I plugged in my Airport Express (previously purchased) and could not make it work. Lots of blogs online about this. I struggled for about 3 hours. Finally gave up, went to Best Buy, bought a Netgear router, and in 10 minutes my Internet access was faster than ever. I use citrix at home for work. With my prior modem I would get "punted" every 10 minutes or so. Turns out it was my modem. Now citrix works great. I am writing this review because I am impressed with the modem and the netgear router. I spent about $150 combined. Definitely worth it.
