Summary: Dual band with cable modem with 300MBps is great. 2.4GHZ has great range . 5GHz has medium range but clean channel. 2-Ethernet ports were kind of lower than standard 4. But I needed only one to begin with. Docsis 3.0 cable modem makes sure it's supported by most cable providers. Very easy setup.
Summary: I have owned NetGear routers before and had very good luck with them. This modem routers is no exception. Excellent routers for the money. Very fats and the signal is really strong. Much better than the one I was renting from the cable company, and it saves me the cost of the monthly rental.
Excerpt: Connected to Comcast. Comcast activation website popped up on computer right away. Once activation was done, Internet service worked just fine. Tweaking wifi and other settings wasn't hard either.
Summary: With the Uverse equipment I was forced to rent and use, I was barely getting 12Mbps download(paid for 18Mbs) on wifi and I had a lot of disconnects/buffering issues. I made the switch to cable and bought this modem and now I'm getting 30Mbs download via 2.4ghz band and 60Mbs download via 5ghz band.
