Purchased this modem in 4/20/2015. Spent several hours online with cable company and then Motorola to determine it was faulty and needed to be replaced. Motorola not good company to deal with! Yes, they will replace but still waiting for call back with return info. After this is done they will send me replacement if I pay $15. Then I have to pay to ship broken one back, another $15! Not good customer support. This could mean 5-7 business days without internet. Not something I could recommend. 8/7/2015
