    Excellent modem, if you are with Comcast though it doesn't make much of a difference. I blame Comcast though, the modem is top notch

    Don't rent your modem from the cable company! This is the exact same modem that Comcast uses and then charges $10 a month. I bought this device and hooked it up. 90+mps right out of the box without a single outage in months. Very rugged and easy to install. Save yourself a ton of money and purchase one instead of renting.
